Subject: [SLR-Mail] No. 711: Message from Kunming From: Wang Wu, Kunming > ******************************************************************************** SLR Electronic Mail 2000-12-21 17:20:00 UTC Message No. 711 ******************************************************************************** Author: Wang Wu, Kunming Subject: Message from Kunming Dear colleagues, Our SLR system has some troubles since Dec.15. The power output of the discriminator was not normal, so it affected the discriminator output. >From Dec.16, the MCP-PMT was not normal too. We first repaired the power of the discriminator, and then changed the C-SPAD as the detector on Dec.18, but forgot to set the SR620 correctly. The data of these days has a large bias. After a check on Dec.19, the system has recovered normally with the new detector: C-SPAD and the new ground target data. Merry Christmas!
