根据宇宙线物理实验的要求,我们研制了一种双宽CAMAC插件,它装有九路恒比定时甄别器。各路的幅度一时间移动(也称时间步移)均小于±100ps,而其造价仅相当市售单路者。 所谓恒比定时,是取前沿上 高度相当于脉冲幅度固定比例的 点作为定时瞬间的定时方法。此 方法的特点是,定时瞬间几乎与 脉冲的高低无关。通常,恒比定 According to the requirements of the cosmic ray physics experiment, we developed a double wide CAMAC plug-in unit, equipped with a nine-way constant ratio timer discriminator. The magnitude of each movement over time (also known as time-step) are less than ± 100ps, and its cost is only a considerable market alone. The so-called constant ratio timing, is to take the height of the front edge of the pulse amplitude is proportional to the fixed point as a timing method of instantaneous timing. The characteristic of this method is that the timing moment has almost nothing to do with the pulse level. Normally constant
