摘要:

Mu 2 e电磁量能器是由两个由SiPM读出的未掺杂的平行六面体CsI晶体盘制成的。在一个磁盘中有674个晶体,每个晶体由两个SiPM的阵列读出。读出电子学由两种类型的模块组成:1)前端模块承载整形放大器和高压线性调节器;由于一个前端模块与一个SiPM接口,因此整个量热计总共需要2696个模块; 2)波形数字化器提供进一步的放大水平,并且以12- 15的采样频率$200\ \text{M}\text{Hz}$数字化SiPM信号。位ADC分辨率;由于一个电路板数字化从20个SiPM接收的数据,因此总共需要136个电路板。读出系统的工作条件是恶劣的:电离剂量的$20\ \text{krads}$,中子通量的$10^{12}\ \mathrm{n}(1\ \text{MeVeq})/\text{cm}^2$,磁场的$1\ \text{T}$和真空水平的$10^{-4}\ \text{Torr}$。报告的读出系统和鉴定测试的描述。

英文摘要:

The Mu2e electromagnetic calorimeter is made of two disks of un-doped parallelepiped CsI crystals readout by SiPM. There are 674 crystals in one disk and each crystal is readout by an array of two SiPM. The readout electronics is composed of two types of modules: 1) the front-end module hosts the shaping amplifier and the high voltage linear regulator; since one front-end module is interfaced to one SiPM, a total of 2696 modules are needed for the entire calorimeter; 2) a waveform digitizer provides a further level of amplification and digitizes the SiPM signal at the sampling frequency of $200\ \text{M}\text{Hz}$ with 12-bits ADC resolution; since one board digitizes the data received from 20 SiPMs, a total of 136 boards are needed. The readout system operational conditions are hostile: ionization dose of $20\ \text{krads}$, neutron flux of $10^{12}\ \mathrm{n}(1\ \text{MeVeq})/\text{cm}^2$, magnetic field of $1\ \text{T}$ and in vacuum level of $10^{-4}\ \text{Torr}$. A description of the readout system and qualification tests is reported.
