两个装有不同数量裂变材料（浓缩90%的铀-235）的裂变室已被制造出来，用于热核聚变装置中的中子通量探测。在热中子源中验证了中子信号的特征及其与其它信号的区别，以及阳极和阴极之间的高压平台。在加速器快中子源上标定了两个裂变室在七个能级上的能量响应，结果与模拟结果符合得很好。
Two fission chambers with different amounts of fissile material (enriched 90% uranium-235) have been manufactured for neutron flux detection in a thermonuclear fusion device. The characteristics of neutron signal and its discrimination from other signals, and a plateau of high voltage between the anode and cathode have been validated in a thermal neutron source. The energy responses of the two fission chambers at seven energy levels have been calibrated in an accelerator fast neutron source and the results agree well with the simulations.
