        The ILC/CLIC common issues for the positron sources 30m
        For unpolarized e+, the ILC is developing the conventional source, as the auxiliary source while CLIC is developing, as its baseline, an hybrid target source composed of a crystal-radiator, where the channeling process takes place, followed by an amorphous target where positrons are generated. For polarized e+, the ILC study considers the Undulator option as the baseline while the Compton schemes are alternative options. The CLIC study considers the Compton schemes as the baseline while the Undulator is an alternative option. Independently of the options, many common issues need a careful study: thermal and mechanical effects in the e+ targets, capture systems (Adiabatic Matching Devices and RF systems), remote handling, (pre)damping rings acceptance, reliability, cost estimate, ... In November 2008, an "ILC/CLIC e+ generation" working group was set-up at Chicago, in order to develop the synergy between the ILC and CLIC e+ studies. A review of the common technical issues and studies will be presented including the existing technical and tests facilities where further tests could be performed.

        Polarized gamma-source based on intra-cavity Compton backscattering. 30m
        This scheme employs Compton backscattering from a 4 GeV linac’s e--beam inside a CO2 laser amplifier cavity. The scheme relies on commercially available lasers and does not require positron stacking. The required number of positron per bunch is produced in every laser shot at 50 Hz repetition rate. The essential features of this scheme are: using a mid-IR CO2 laser that provides 10 times more laser photons per Joule to compare with a solid-state laser, and the most energy-efficient back-scattering geometry. This allows attaining the gamma-ray production of 1 photon per electron, Ng/Ne-=1, as has been demonstrated in the experiment.The conversion efficiency of the polarized gamma photons into polarized positrons is expected to be about 2%. Therefore, every positron requires, as precursors, fifty gamma photons. With Ng/Ne-=1, and 5-10 nC/bunch delivered from the electron linac, correspondingly ten-five consecutive Compton IPs will be required to accumulate the gamma flux for the 1-nC positron bunch production. Intra-cavity positioning of the interaction point (IP) allows laser energy recycling to compensate for optical losses inside the cavity (assumed here 2-5% per round trip). The linac’s electron beam is formatted into: trains of ~300 bunches at ~5-12 ns spacing and 50-150 Hz repetition rate. This matches the optimum regime for the energy extraction from the laser. The 1-nC positron bunches, produced on a target by the Compton-scattered gamma-photons, will be injected into a dumping ring were reformatting into bunch separation required for ILC or CLIC will be achieved. Simulations and experiments on laser pulse injection and train production inside the Compton cavity are in progress at BNL.

        Status of experiment with 2-mirror cavity at KEK-ATF 30m
        We performed a photon generation experiment by laser-Compton scattering at the KEK-ATF, aiming to develop a Compton based polarized positron source for linear colliders. In the experiment, laser pulses with a 357 MHz repetition rate were accumulated and their power was enhanced by up to 250 times in the Fabry-Perot optical resonant cavity. We succeeded in synchronizing the laser pulses and colliding them with the 1.3 GeV electron beam in the ATF ring while maintaining the laser pulse accumulation in the cavity. As a result, we observed 26.0+/-0.1 photons per electron-laser pulse crossing, which corresponds to a yield of 1E8 photons in a second.

        Present roadmap for the CLIC positron sources 30m
        In a first stage, the CLIC baseline assumes unpolarized positrons using the enhanced photon yield in an axially oriented crystal due to channeling process. The generated photons are sent, a few meters downstream, to an amorphous target where e-/e+ pairs are produced. This set of targets, so-called hybrid target, is followed by a classical Adiabatic Matching Device and a pre-injector linac working at 2 GHz, accelerating e+ up to 200 MeV. In a second stage, the CLIC source assumes polarized positrons. The latter requires polarized photons which can be produced by a Compton process. The photon flux coming out from a Compton process is not sufficient to obtain the requested charge and a stacking process is required in the Pre-Damping Ring (PDR). Three options are under study: i) Compton backscattering taking place in a so-called “Compton ring”, where an electron beam of 1 GeV interacts with circularly-polarized photons in an optical resonator; ii) Compton Energy Recovery Linac (ERL) where a quasi-continual stacking in the PDR could be achieved; iii) "Compton Linac" where a CO2 laser interacts with a high current electron beam inside several optical cavities and which would not require stacking. A positron source based on undulator scheme is also investigated as possible alternative option. Finally the roadmap should include an e+ source for a CLIC machine working at 500 GeV but with a doubled bunch charge.

        Analytic Study on Compton Rings 30m
        Compton ring-based sources of polarized positrons have some advantages but suffer from a large energy spread of circulating electrons. One of the methods to overcome this limitation is to employ the double-chicane insertion. The report presents results of an analytic study on the Compton rings with double chicanes. Ability of such a ring to operate in the continuous regime due to reduction of the spread is demonstrated. Simulations verify the analytic results.

        Recent results from the Compact Light Source 30m
        Past research at SLAC introduced a new x-ray source concept, a miniature synchrotron light source [1]. This research led to the formation of a corporation, Lyncean Technologies, Inc. to develop the Compact Light Source. The prototype development of the Compact Light Source (CLS) is now complete [2]. The CLS, as reformulated at Lyncean, is a near-monochromatic, tunable, homelab-size, hard x-ray source with beamlines similar to the x-ray beamlines at the synchrotrons--but it is about 200 times smaller than a synchrotron light source. The compact size is achieved using a “laser undulator” and a miniature electron-beam storage ring, in other words--inverse Compton scattering in a miniature storage ring. This presentation will introduce the principles of the Compact Light Source. Next, the design and the testing phase will be discussed. The second “Beta CLS” developed for the “ATCG3D” is being commissioned now [3]. Hardware from both the CLS prototype and the Beta CLS will be shown to illustrate the scope of the effort. The presentation will include the Beta CLS commissioning status and latest experimental results with protein crystallography. Finally, we present recent results from the development of new imaging techniques using the CLS [4]. References [1] Z. Huang and R. D. Ruth, "Laser-Electron Storage Ring”, Phys. Rev.

        Polarized electrons for polarized positrons 30m
        While a polarized positron beam offers a significant probe at a collider facility, it is also an important tool for the study of nucleon structure at a fixed target facility such as Jefferson Lab. For instance, a model independent extraction of the generalized parton distributions from deeply virtual Compton scattering requires both polarized electrons and polarized positrons. The feasibility of a polarized positron source based upon the CEBAF polarized electron source will be presented. In this scheme, the longitudinal polarization of the electron beam is transfered to positrons via intermediate elliptically polarized photons generated in a suitable conversion target via electron polarized bremsstralhung. This talk will discuss recent developments and status of a suitable polarized electron source, and progress for the characterization of a polarized positron source for a hadronic physics program.

        Low energy polarised positron source for the SuperB project 30m
        The SuperB project is a new project of flavour factory that takes into account a luminosity in the ordrer of 10Exp36. This very ambitious goal is achievable thanks to a new colliding schem, the crab waist, successfully tested in DAFNE, Frascati. In this framework the possibility to dispose of both polarised electron and positron beams is extremely attractive since this will allow an increasing of the physics events rate without increase the detector noise. Fiorst consideration on a possible scheme for a polarised positron source for the SuperB project will be presented.

        Study of an hybrid source using channeling 30m
        The CLIC study consider the hybrid source using channeling as the baseline for positron production. Basically, the hybrid source uses a few GeV electron beam impinging on a crystal tungsten radiator. With the tungsten crystal oriented on its <1 1 1> axis its results intense relatively low energy photons due to channeling radiation and coherent bremsstrahlung. Those photons are then used to impinge on an amorphous tungsten target to produce positrons from e+e- pairs creation. In my presentation I will describe the study of the positrons variation yield and the peak energy deposition density in the target according to the distance between the crystal and the amorphous targets.

        Low energy e- driven e+ source for ILC 30m
        An electron driven positron source for ILC is studied. The electron energy is relatively low, 2.2 GeV. In such energy, the production target can be thinner than that for high energy case; The thinner target causes higher positron yield per electron normalized by its energy. On the other hand, higher intensity electron beam is required to recover the real positron yield (un-normalized by its energy) due to the low electron energy. Lithium lens capture optics increases the capture efficiency and compensate this intensity issue. As target, a liquid Pb system is assumed. Liquid Pb and BN window may have very high performance limit on the positron generation, but Pb boiling is a possible problem. An optimization by considering those facts is made.

        The 300 Hz generation option of ILC positron source 20m
        The 300 Hz generation option is a conventional positron source driven by a electron beam. The beam has the characteristic multi-bunch structure. ILC requires tremendous number of positrons in a pulse. This makes positron production in ILC very challenging. However, the repetition of the ILC, 5 Hz, is rather slow. We have 200 m sec interval between two pulses. In the 300 Hz option, we produce positrons in rather long time, 30 m sec, in order to make target issue easy.

        The computer simulation code PPS-Sim has been developed to provide a user friendly framework for modelling a polarised positron source for a next linear collider. The program is based on Geant4 and can calculate yield and polarisation of produced positrons, beam parameters (beam size, emittance, mean energy), and energy deposition in source components. The simulation includes polarisation transfer in the positron production target, and depolarisation effects, as well as spin precession in the electro-magnetic field of the capture optics. The source layout can be configured using a graphical user interface based on Qt. An internal analysis package allows the immediate evaluation of the results, which can also be saved as ROOT files. PPS-Sim is freely available from the web page (http://pps-sim.desy.de).

        Analysis of circular polarization of - quanta with energy 10-30 MeV using Compton-polarimeter. 30m
        Recently the proof-of-principle experiments were carried out where a circularly polarized beams of -quanta with energy MeV have been produced in order to generate longitudinal-polarized positrons [1, 2]. In [1] the circularly polarized -beam was obtained via Compton backscattering of circularly polarized laser photons by an electron beam with energy 1.28 GeV.For real positron sources a required intensity of a laser flash may lead to significant contribution of a non-linear Compton process that leads to deterioration of polarization of a resulting -beam. The direct measurement of a -beam circular polarization will allow not only to estimate a validity of theoretical calculations, but also to use the obtained information for simulation of polarization characteristics of positrons. We offer to use a Compton polarimeter for this purpose where the recoil electrons from a circularly polarized -quanta scattering in a thin iron magnetized target are detected. We have performed simulation of Compton-polarimeter using CEANT4 code. For the 0.2 mm target thickness and 20 MeV photons we obtained the electron yield from Compton and pair production processes. Calculations show that energy-angular selection of the outgoing electrons corresponding to the acceptance of the polarimeter allows to suppress a contribution from pair process down to a few percent level. For the photon polarization error as low as 10% it is necessary to detect ~ 10 electrons. 1.Omori T., Fukuda M., Hirose T. et al. Phys. Rev.

        Polarimetry at the Positron Source of the ILC 30m
        With the ILC baseline design polarized positrons will be delivered. To optimize and control the positron beam, also the polarization measurement close to the creation point is recommended. Taking into account the positron beam parameters at the source, possible methods for polarimetry include a Compton transmission polarimeter (directly downstream the capture section) and a Bhabha polarimeter (operated at few hundred MeV). Alternatively, the polarization can be measured using a Compton polarimeter after positrons passed the damping. Fast reversal of positron helicity is recommended but not essential for polarimetry at the source. However, it is decisive for precision measurements at the IP and will be discussed shortly.

        Lithium Lens Simulation for ILC Positron Source 30m
        The Lithium Lens (LL) is one of the possible candidates for positron collection optic elements of an ILC positron source. The collection efficiency of positrons after the conversion target is a key issue of the source design. The LL has been simulated using Geant4-based application (PPS-Sim) that allows to simulate the production of polarized positrons and their tracking in electromagnetic fields. In order to get highest positron yield and polarization, the optimal lens parameters are determined for the base-line ILC positron source. The efficiency of LL is compared with others schemes of positron capture as Adiabatic Matching Device and Quarter Wave Transformer.

I will present a capture section and pre-accelerator design for the CLIC positron source, in the baseline configuration (non polarised positrons), together with simulation results of the captured beam.

        Compton Ring for Nuclear Waste Analysis 30m
        Compton storage rings at maximal energy of electron beam about 350 MeV is promising intensive source of hard photons for analysis of nuclear waste. Two lattices of such rings are discussed. Dynamics of electron bunches circulating in a storage ring and interacting with high-power laser pulses is studied by simulation. Parameters of both electron and photon beams are presented.
