This system consists of high pressureionization chamber detector filled with Xe gas, 8051 single chip control unit and low current measuring amplifier.
The optimum parameters, such as electron current and voltage for ionization, acceleration voltage, retarding voltage, gas inlet pressure, were determined by experiments.
通过实验确定了最佳参数，其中包括：离化电子电流和电压、加速电压、阻止电势、供气压力等。
