------------------------------------------------------------ Date: Fri Aug 11 16:44:33 2000, Shift: 08:00-16:00 Supervisor: RD, with: ZIS Log book#4 pages 49 - 55 Shift Summary: ------------------------------------------------------------ 1. DEAD 2. run 2188 ZDC LED before work run 2196 ZDC LED after work 3. Today we looked at LED response in ZDC to identify a possible gain shift. The result of the study is that there is no shift. The single neutron peak became more difficult to see in the ntuple plots because of additional background that must be related to tune of the machine. During this work we checked DC offfsets of sum circuits, and made the Camac ADC gate for the unattenuated signal 10 nsec earlier. The Forward spectrometer has been moved from 8 to 5 degrees. ------------------------------------------------------------
