Modes of operation at E3 Single shot operation: No major radiation issues expected High rep. rate targets: Long term radiation activation monitoring Pulsed power device High voltage Target fabrication and storage considered: Storing of potentially flammable materials Beryllium will be used, safety measures need to be taken Activation issues taken into account: Low Z (Al materials) preferred for all equipment Replaceable parts like screw hole insets Geometry and direction of shooting considered for each experimental setup in order to minimize radiation issues E2 betatron might be moved to E3 (temporalilly): All concerns with high energy electrons might arise Beam dumps needed Prealignment desktop station outside chamber to be used for more complicated crystals Warm dense matter is an intermediate state between solids and ideal plasmas. It is readily created in laser experiments, ICF implosions and common place in astrophysics, in particular inside planetary cores. It is a difficult regime to describe theoretically since at the temperatures between 1 and 100 eV and solid densities the electron degeneracy is significant and the ions are strongly coupled, so the quantum effects and inter-particle interactions cannot be ignored making the theoretical description of WDM very difficult. The experimental measurement of state variables including temperature, density, pressure and ionization in WDM are of an upmost importance for verification of equation-of-state models.

Targets at P3 Proton heating target Focusing magnet Types of targets expected: Gas jet (low and high density jets) – H, He, Ar, Ne, N, Xe, O2, doped with high Z elements Mass limited targets Simple foil targets for backlighting and particle acceleration (some activation concerns) Low density foam targets Liquid crystals (for ultrathin film formation for particle acceleration) Solid Composite complicated targets with higher Z shielding – more serious concerns Rasters for high rep. rate operation – both simple and ha Potentially cryo targets A priory no target is excluded Proton heating target Focusing magnet Warm dense matter is an intermediate state between solids and ideal plasmas.

High repetition system Large rasters of solid targets (potentially complicated) planned for high rep. rate operation There are already some programmes working on high rep. targetry for ELI facilities: EUCALL – coordinated between EU XFEL, HZDR, – WP6 (HIREP) – coordinator: Danielle Margarone ELI TRANS – ELI Beamlines coordinator: Michal Smid – dedicated full-time position (not yet assigned) Main issue: replacement of rasters/cartriges without breaking vacuum – robotic arms?

Robotic replacement systems Robotic arm or 4-axis atumatic manipulator considered for target raster replacement Fanuc robot: Manufacturer: http://www.fanuc.eu Considered for Apollon for high rep. rate targe replacement UR robot: Manufacturer: http://www.universal-robots.com/ More compact and lighter than Fanuc Remote manipulator (MSM – Master-Slave Manipulator): Similar at operation at JET tokamak and nuclear facilities Not vacuum compatible, extra expense for development Not very high precision movement and positioning TIM insertion mechanism: Foreseen in the future, but mainly for diagnostics Not fast, very expensive Safety related challenges: Vacuum compatibility, robotic arm tests planned Activations, not a major concern as most robots have major part made of light materials, some electronics cannot be avoided, not in constant operation, so shielding option is considered Warm dense matter is an intermediate state between solids and ideal plasmas.
