keyword=New HV settting on Preshower18 of RHRSI changed the HV of Preshower18 of RHRS (7th channel, slot 11 in HV gui) from -990 to -1030 to increase the gain. This is applied on the production run 20643 only, shown in figure1. It looks the gain is still a little small. So I increase HV from -1030 to -1090 and it is applied from 20644, shown in figure2. Now I think it is fine.
