摘要
ALICE/PHOS实验控制单元由RCU升级为SRU,实现更稳定的远距离点对点控制读出以及每块前端电子学板20MB/s的读出速率。结合新研制生产的90块前端电子学板在SRU系统下的测试结果,着重分析了SRU读出控制方式以及电子学板信号链路的测试结果,评估了基线漂移的影响并由大量测试结果表明,现行设计的前端电子学板满足电子噪声小于5MeV的能量分辨率要求。
Upgraded from Readout Control Unit in ALICE/PHOS experiment, the Sealable Readout Unit has more stable point to point readout and up to 20 MB/s readout rate per Front - end Electronic Card. Based on the test results of newly designed 90 FECs in SRU system, analysis focused on readout control mechanism, the results of testing signal chain of FEC and evaluated the influence of pedestal shift. Energy resolution of FEC was proved under 5MeV by plentiful test results.
