利用多道分析器作多定标操作,可以简便地实现一些时间分析测量。如可以用来测量反应堆内中子随时间的几率分布,也可以采用脉冲中子源法,利用这种装置来测量反应堆内控制棒或毒物吸收中子的当量(即引入反应性的大小),即测量中子脉冲在连续的、相等时间间隔(如4096个间隔)内的计数分布等。 随着堆物理实验的进一步开展,要求作反应堆内的多点同时测量,以了解反应堆活性区内不同位置上在相同的时间间隔内中子脉冲的分布规律。这一功能可以由多路多定标转换器作为4096道分析器的一个接口来配合完成。另外,利用它还可以对多个样品的短寿命同位素作半衰期的多路同时测量等工作。 该装置主要采用P-MOS中(小)规模集成电路,具有轻便、灵活的优点。具体电路请见文献[4]。
The use of multi-channel analyzer for multi-calibration operation, you can easily achieve some time analysis and measurement. If neutrons can be used to measure the probability distribution of neutrons in the reactor over time, a pulsed neutron source method may also be used to measure the equivalent of neutron absorbed by the control rod or poisons in the reactor (ie, the magnitude of reactivity introduced) Ie measuring the distribution of counts of neutron pulses in successive, equal time intervals (eg 4096 intervals). With the further development of physical physics experiment, it is required to make simultaneous multi-point measurements in the reactor to understand the distribution of neutron pulses at different positions in the active region of the reactor at the same time interval. This feature can be done with a multiplexer and multi-scale converter as an interface to the 4096 analyzer. In addition, the use of it can also be a number of samples of short-lived isotope half-life multi-channel simultaneous measurement work. The device is mainly used P-MOS (small) scale integrated circuits, with light, flexible advantages. See the specific circuit [4].
