报道一套轻重离子焦面探测器系统。该探测器系统是以四个矩形正比管和一个电离室堆积而成。工作气体为70％Ar+30％CH_4。桌上试验结果为,位置灵敏探测器分辨约0.95mm,积分非线性好于0.2％。在北京HI-13串列加速器上,以66MeV~(12)C束流、工作气压
A light and heavy ion focal plane detector system is reported. The detector system is based on four rectangular proportional tube and an ionization chamber stacked. Working gas is 70% Ar + 30% CH_4. The table test results show that the position sensitive detector resolution of about 0.95mm, the integral nonlinearity better than 0.2%. In Beijing HI-13 tandem accelerator to 66MeV ~ (12) C beam, working pressure
