摘要
A multi-anode transverse-field gas ionization chamber (MAIC) for heavy-ion identification at the Radioactive Ion Beam Line in Lanzhou (RIBLL)[1] was developed (as shown in Fig.l). It consists of cathode plate, Frisch grid and four anode plates (20, 40, 80, and 136 mm wide respectively). The MAIC works at 104 Pa of flowing gas P10 (10% CH4+90% Ar). A three-component a-source was used for determining the energy
