Investigation of a gas catcher/ion guide system at the Warsaw cyclotron

NESTER ACC; The properties of a gas-catcher/ion guide system, connected to a mass separator at the Heavy Ion Laboratory of Warsaw University, were investigated by using the α-decay recoil products 219Rn and 215Po, obtained from a 223Ra source. The “plasma effect” was studied by using a 14N beam with intensities ranging from 7 to 64 particledot operatornA, which correspond to power depositions between 1.6 dot operator 1016 and 7.2 dot operator 1017 eV/s for helium pressures of 75 and 380 hPa, respectively.
