A start to end simulation of the laser plasma wakefield acceleration experiment at ESCULAP

We present a start to end (s2e) simulation of the Laser-plasma Wakefield Accelerator (LPWA) foreseen as the ESCULAP project. We use a photo injector to produce a 5MeV 10 pC electron bunch with a duration of similar to 1 ps RMS, it is boosted to 10MeV by a S-band cavity and then compressed to 74 fs RMS (30 fs FWHM) by a magnetic compression chicane (dogleg). After the dogleg, a quadrupole doublet and a triplet are utilized to match the Twiss parameters before injecting into the subsequent plasma wakefield. A 40TW laser is used to excite plasma wakefield in the 10 cm plasma cell. An optimized configuration has been determined yielding at the plasma exit an electron beam at 180 MeV with energy spread of similar to 4.2%, an angular divergence of 0.6 mrad and a duration of 4 fs.
