Research of a charge sensitive device for the search of the time reversal symmetry violation using kaon decay

TREK实验是一项利用介子衰变寻找时间反转不变性的实验，计划在日本质子加速器研究综合体(J-PARC)进行。研究了高速信号到数字的转换方法以及充电信息和定时信息的读取方法。并利用Trek实验开发了实用的读出模块。在本研究中，我们了解到一种使用闪存ADC的方法是有效的。并研制了具有足够的电荷分辨率和时间分辨率的闪光模数转换模块。

TREK experiment is an experiment of the search for the time reversal invariance using kaon decay, planned at Japan Proton Accelerator Research Complex(J-PARC). We researched the high speed signal to digital conversion methods and the reading the charge information and the timing information. And we developed the practical read-out module to use TREK experiment. In this study, we understood that a method using the flash ADC is effective. And we developed a flash ADC module which has the sufficient the charge resolution and the time resolution.
