回顾了我们在FOPI-TOF升级项目框架内开发带状阳极MRPC的情况。对于计数器读数,我们开发了一种快速FEED(前端电子设备),在高带宽(α∼fδ1000 MHz)下提供高增益(∼200)和一种新的σt⩽15ps内部分辨率的TAC数字化系统。为了优化信号形状的变化,研究了条带/节距结构和间隙数目。
The status of our development of strip anode MRPCs in the framework of the FOPI-ToF upgrade project is reviewed. For the counter readout we have developed a fast FEE (front-end-electronics) offering a high gain (α∼200) at high bandwidth (δf∼1000MHz) and a new TAC-digitization system with an internal resolution of σt⩽15ps. In order to optimize the signal shape variations, strip/pitch configurations and number of gaps have been investigated.
