【摘要】 介绍一种由电荷灵敏前置放大器、主放大器、甄别器、成形电路所组成的一体化电路。该仪器主要用于计数测量中,它主要适应于高灵敏度的3He中子探测器,同时也可以用于其他重离子探测器,该仪器的输出脉冲可直接与CMOS或TTL逻辑电平兼容。它有功耗低,体积小,灵敏度高,便于野外使用等特点更多还原

【Abstract】 A hybrid circuit consists of charge sensitive preamplifier,main amplifier,discriminator and shaping circuit was described.This instrument has characteristics of low power consumption, small volume,high sensitivity,potable and so on,and is convenient for use in field. The output pulse of this instrument may directly consist with CMOS or TTL logic level.This instrument was mainly used for count measurement,for example,for high sensitive 3He neutron detector, mean while also may used for other heavy ion detectors.更多还原
