1 ELI PARAMETERS SPACE FROM ANALYTICAL MODEL C. Ronsivalle ELI meeting

2 KEY FIGURES OF SERAFINI ANALYTICAL MODEL Assumptions with

3 ELI SPECIFICATIONS 1212 From requirement #2

4 INPUT DATA FOR THE MATLAB PROGRAM Laser pulse energy U=1 J Laser photon energy h =2.4 eV  = Collision angle  =0 Electron beam energy=360 MeV (first ELI ip)  t=4 ps  t=5 ps HYBRID scheme FULL-C band Wp1 point Q=250pC,  /  =0.6*10 -3

5 Q=250pC,  /  =0.6*10 -3  t=4 ps E=360 MeV Max SPDopt values  x values for max SPDopt SPD is per shot

6 E-BEAM PARAMETERS SPACE: ISO SPECTRAL DENSITY CURVES The red point ( ) corresponds to wp1 for the hybrid scheme Contour lines plot for Q=250 pC and  t=4 ps. The iso spectral density curves correspond to the peak values on the curves SPDopt vs  x. For frip=100 Hz and SPDmax=10 4 The region below curve 100 defines the parameters space for nrf=1 The region between curves 100 and 50 defines the parameters space for nrf=2 and so on……. nrf=required number of bunches

7 E-BEAM PARAMETERS SPACE: ISO SPECTRAL DENSITY CURVES The red point ( ) corresponds to wp1 for the hybrid scheme Contour lines plot for Q=250 pC and  t=4 ps. The iso spectral density curves correspond to  x=20 µm 23 means nrf=5
