  1. Design of High Gradient Laser Plasma Accelerating Structure (WP3)Update B. Cros (CNRS), ZulfikarNajmudin (ICL) 19th November 2018

  2. Overview and work repartition REMINDER • 1st stage: stronggain, 2nd stage: control, filtering and stabilityduringacceleration • Scientific and technical challenges related to stability and synchronisation WP2 WP4 WP4 WP3 WP3 WP5 B. Cros, EUPRAXIA November 2018

  3. WP3 : all taskscompleted B. Cros, EUPRAXIA November 2018

  4. Plasma targetcharacteristics have been compared B. Cros, EUPRAXIA Mid-Term Review B. Cros, EUPRAXIA November 2018

  5. Main conclusions on plasma targetdetermination • Plasma stability and laser qualitywilldetermine the stability of the electronbeamfrom LPI and LPA • Gascellmost stable and suitable for densitytailoring of short plasma (injector) • Plasma channels more suitable for guiding in the QL regime (accelerator) B. Cros, EUPRAXIA November 2018

  6. Targetedparameters for electronbeamgenerated by LPI • Energy 150 to 400 MeV, 1 GeV B. Cros, EUPRAXIA November 2018

  7. LPI and LPA parameter range • LPI similar for 150MeV to 400MeV, Gascell • LPI at 1GeV, guidingneededchannel • LPA in QL regime, guidingneeded • Use of 2 stages allows for electronselectionwith transport system and beamshaping B. Cros, EUPRAXIA November 2018

  8. LPI + LPA conceptual design < LPI 1. Gascell 2. Cap discharge 3. Gaz jet LPA Plasma channel Cap discharge / Laser generated B. Cros, EUPRAXIA November 2018

  10. SAC recommendations for WP3 Rec 9: LPI & LPA selected Joint Exp in preparation for stabilitystudy of LPI Rec 10: plasma diagnostics described MS Rep 3.4 Laser/e- alignt and synch : to do, interaction WP4 & 5 thisweek Rec 11: to do Need 10Hz facility for testing prototypes (currentoperation at 0.03 Hz) Rec9. SAC recommends decreasing this number [of configurations under investigation] in the short term with appropriate metric and thereafter to perform tolerance studies for the main parameters. Rec 10. SAC recommends detailed evaluation of plasma & laser diagnostics, laser beam/electron beam alignment and synchronization for the CDR. Rec11. SAC recommends performing a thermal study of the plasma cell considering the significant increase of laser average power and to prototype the plasma cell according to final design for any activity following the design study.
