用于精密时间记录的单片时间展宽器

A Monolithic Time Stretcher for Precision Time Recording

Gary S. Varner, Larry L. Ruckman

摘要:

在粒子物理探测器的典型米长尺度上,识别只包含上/下夸克(π介子)的轻介子和包含奇异夸克(K介子)的轻介子需要能够测量飞行时间的仪器,分辨率为20 ps。在过去的几年中,大量的廉价,多通道时间数字转换器(TDC)芯片已经成为可用的。这些器件通常具有数百ps范围的定时分辨率性能。提出了一种技术,它是一个单片版本的“时间拉伸器”的解决方案,采用了贝尔飞行时间系统,以解决分辨率需要和内在的多击中TDC性能之间的差距。

英文摘要:

Identifying light mesons which contain only up/down quarks (pions) from those containing a strange quark (kaons) over the typical meter length scales of a particle physics detector requires instrumentation capable of measuring flight times with a resolution on the order of 20ps. In the last few years a large number of inexpensive, multi-channel Time-to-Digital Converter (TDC) chips have become available. These devices typically have timing resolution performance in the hundreds of ps regime. A technique is presented that is a monolithic version of ``time stretcher'' solution adopted for the Belle Time-Of-Flight system to address this gap between resolution need and intrinsic multi-hit TDC performance.
