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...

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...

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...

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...

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...
