摘要:

衰变$K^+ \to π^+ν\barν$的分支比对新物理很敏感; NA 62实验将测量到它在10%以内。为了从具有终态光子的通道中排除占主导地位的背景,大角度否决(LAV)必须在非常大的能量范围内以优于1 ns的时间分辨率和10%的能量分辨率检测粒子。我们的定制读出板使用与TDC耦合的超阈值时间转换器作为满足这些要求的简单解决方案。2010年夏天,读出系统的原型与ANTI-A2大角度否决模块一起在CERN进行了广泛的测试。

英文摘要:

The branching ratio for the decay $K^+ \to π^+ν\barν$ is sensitive to new physics; the NA62 experiment will measure it to within about 10%. To reject the dominant background from channels with final state photons, the large-angle vetoes (LAVs) must detect particles with better than 1 ns time resolution and 10% energy resolution over a very large energy range. Our custom readout board uses a time-over-threshold discriminator coupled to a TDC as a straightforward solution to satisfy these requirements. A prototype of the readout system was extensively tested together with the ANTI-A2 large angle veto module at CERN in summer 2010.
