Some excellent high order calibration pulse waveforms of the spectrum characteristic are obtained by theoretical analysing and computer scanning.However we compare them with step pulse generally using at home station network.The calibration preiscion for the short perodic band pass is greatly improved.Meantime,those above mentioned are compared with the second and third order pulse using at abroad,we found that they are of a characterstic of the response waveform.The calibration precision for the band pass of the long period is not only improved,but also its precision is not decrease.On the other hand,they are easy to generate and apply.

A method adopting the charge analog digital conversion technique to calibrate a current scintillation detector is described. Each pulse charge produced by a single particle is collected and recorded. Calculating the mean current, the sensitivity of the detector is measured. The results agree with the measurement presented by the traditional direct current method within ±8%. This new method can get higher accuracy, subtract background easily and it does not depend on the intensity of the radiation source. By applying time-of-flight method, it is capable of particle discrimination. It can separate the pulse charge produced by neutron from that produced by gamma in a neutron-gamma mixed field. The sensitivity of current detector to each type of particle can be measured separately. This method is appropriate to calibrate the sensitivity of the pulse current detector when the single charge pulse has high signal-to-noise ratio.

采用电荷模数转换记录单个脉冲电荷的方法,标定了单能射线在电流型闪烁探测器中产生的平均电流,从而得到其灵敏度。标定结果与传统的电流法在±8%的范围内一致。该标定方法准确度高,扣除本底容易,对标定源的强度要求也大大降低。加上飞行时间法,还可对粒子进行甄别,能在中子γ射线混合场中将中子和γ射线的电荷贡献分开,得到探测器对每种射线单独的灵敏度。该方法适用于在单个脉冲电荷信噪比较高的场合下标定脉冲电流型探测器。
