  2. 27. EuPRAXIA electron beam parameters
    Paul Andreas Walker (DESY)
    11/10/2016, 13:55

    The talk will introduce the current study concept of EuPRAXIA. It presents much of the outcome of discussions and meetings over the last year, condensed into flow diagrams and technical tables. These will define the preliminary study version of EuPRAXIA. Input from the PAEPA workshop will be incorporated into these tables and diagrams at the end of the workshop, to include HEP user cases in...

  3. 28. Medical imaging applications at innovative radiation sources
    Alberto Bravin (ESRF)
    11/10/2016, 14:30

    X-ray imaging has been the most important and widespread diagnostic tool in medicine over the last century. Despite its success, for example in imaging bone and dense structures, X-ray diagnostics reaches its limits in the examination of soft tissues, such as small tumours in healthy tissues, or in imaging lungs, vessels, or articular cartilage. Moreover, medical diagnostic imaging requires...

  4. 29. Prospective use of laser-driven sources for X-ray phase contrast imaging
    Alessandro Olivo (University College London)
    11/10/2016, 14:45

    X-ray phase contrast imaging (XPCI) methods have emerged that can potentially transform all areas where x-ray imaging is used - medical and not. XPCI is historically associated with stringent coherent requirements which means it has been mostly implemented at synchrotron facilities; however, the use of laser-based plasma sources could transform this. Although there are now totally incoherent...

  6. 31. Plasma Accelerators as a source of fs X-rays for probing Matter Under Extreme Conditions
    Stuart Mangles (Imperial College London)
    11/10/2016, 16:00

    The betatron oscillations of the electron beam inside a laser wakefield accelerator have been shown to produce bright X-rays with some unique properties: namely they are both broadband and have a femtosecond duration. In this talk I will outline future applications that will use these unique properties to perform time resolved X-ray spectroscopy of matter under extreme conditions.

  8. 33. Inverse Compton scattering from plasma wakefield acceleratedbeams
    Paul Scherkl
    11/10/2016, 16:35

    Generation of hard photon pulses from inverse Compton scattering with plasma wakefield accelerated electron beams is presented. The high beam quality in terms of energy spread and divergence ensures low radiation bandwidth on the order of a few percent within fs-scale pulses. This scheme gets extended to decoupled and yet synchronized multicolor radiation pulses that enable unique control of...

  10. 35. Embryonic thinking of possible EuPraxia vs medical applications synergy
    Marc Verderi (Centre National de la Recherche Scientifique (FR))
    11/10/2016, 17:20

    Electron beams in the 1 - 5 GeV range seem hard to be used for what is regarding medical applications thought as "patient treatment". But it can be that some of the instrumentation techniques developed in the medical may be considered for EuPraxia and, reciprocally, that this new platform may help in providing the medical field some testing and development opportunities. Under the convinced...

  11. 36. Microbeam Radiation Therapy
    Alberto Bravin (ESRF)
    11/10/2016, 17:35

    The intense X-ray beams available at large scales facilities and, in the near future, at compact sources, are also well suited for radiation therapy. A flagship development in this field is microbeam radiation therapy (MRT), which uses very high doses of microscopic beams delivered to tissues in a fraction of a second. These microbeams are very well tolerated by normal tissues while tumoral...

  12. 37. Terrestrial reproduction of space radiation electrons using Plasma Wakefield Accelerators
    Panagiotis Delinikolas
    11/10/2016, 17:50

    Space radiation poses a major hazard both for astronauts and spacecraft electronics, especially during prolonged mission periods. High energy protons and electrons, originated from the sun or deep space, are trapped into the Earth’s magnetic field, forming radiation belts and act as main contributors regarding astronauts’ radiation dose and electronic malfunctions. In this study, the...

  16. 41. Enhancing the efficiency of laser and plasma based accelerators using bichromatic driver pulses
    Mihaly Andras Poscay
    12/10/2016, 10:15

    The importance of the laser and plasma based accelerators is well known. The tuning of the laser and plasma parameters is the crucial point of this technology. Earlier we already have done numerical simulations to determine the beam parameters of a laser driven plasma based electron accelerator, i.e. the parameters of both the laser beam and the victim electron bunch [1]. In a latter study, we...

  21. 46. Search for dark photons using high energy e beams and other applic's
    Matthew Wing (UCL)
    12/10/2016, 13:30

    Given a clean high energy electron beam, new and improved fixed-target or beam-dump experiments are possible. An example is the NA64 experiment which is searching for hidden sector physics such as dark photons using the secondary SPS electron beam at an intensity of ~10^6 e-/s. With the expectation of being able to increase this rate by at least a factor of 100 to 1000, sensitivity to new...

    Nicolas Delerue (LAL, CNRS & Université Paris-Sud)
    12/10/2016, 14:10

    Coherent Smith-Purcell Radiation encodes information about the longitudinal profile of a relativistic beam. We had a succesful measurement campaign at FACET in the US recently and we are now working on accurately mapping the emission in the SOLEIL linac. I will present recent results obtained recently, current work and Research that could be performed with a new versatile test beam facility.

    Ian Bailey (University of Liverpool)
    12/10/2016, 14:25

    The aim of this talk is to give an overview of current and planned positron source technologies. Such sources include electron beams incident on amorphous conversion targets or crystalline targets, as well as gamma-ray positron sources using either Compton back-scattering or undulators to produce gamma-rays which are then incident on thin targets. Currently achievable fluxes and emittances are...

    Gianluca Sarri
    12/10/2016, 14:45

    The generation of high-quality relativistic positron beams is a central area of research in experimental physics, due to their applications in a wide range of scientifi
    c and engineering areas, ranging from fundamental science to practical applications. There is now growing interest in developing hybrid machines that will combine plasma- based acceleration techniques with more conventional...

  30. 55. Beam transport and environment simulation, a biased view.
    Marc Verderi (Centre National de la Recherche Scientifique (FR))
    13/10/2016, 10:00

    The novel acceleration technique of EuPraxia does not seem to induce new problems for what is regarding the simulation. Once the electrons are accelerated, their energy is typical of the "high energy physics" field, and simulation tools used there can be a priori be applied to EuPraxia. Invitation to discuss the first statement of this abstract will be made ; and beam transport tools as well...
