1Generation of high energy laser-driven electron and proton sources with the 200 TW system VEGA 2 at the Centro de Laseres Pulsados显示文摘The Centro de Laseres Pulsados in Salamanca,Spain has recently started operation phase and the first user access period on the 6 J 30 fs 200 TW system(VEGA 2)already started at the beginning of 2018.In this paper we report on two commissioning experiments recently performed on the VEGA 2 system in preparation for the user campaign.VEGA 2 system has been tested in different configurations depending on the focusing optics and targets used.One configuration(long focal length F=130 cm)is for underdense laser-matter interaction where VEGA 2 is focused onto a low density gas-jet generating electron beams(via laser wake field acceleration mechanism)with maximum energy up to 500 MeV and an X-ray betatron source with a 10 keV critical energy.A second configuration(short focal length F= 40 cm)is for overdense laser-matter interaction where VEGA 2 is focused onto a 5 μm thick Al target generating a proton beam with a maximum energy of 10 MeV and temperature of 2.5 MeV.In this paper we present preliminary experimental results.L.Volpe R.Fedosejevs G.Gatti J.A.Pérez-Hernández C.Méndez J.Apinaniz X.Vaisseau C.Salgado M.Huault S.Malko G.Zeraouli V.Ospina A.Longman D.De Luis K.Li O.Varela E.García I.Hernandez J.D.Pisonero J.Garcia Ajates J.M.Alvarez C.García M.Rico D.Arana J.Hernandez-Toro L.Roso 2019High Power Laser Science and Engineering2019,7,2:0
