ion chamber reading 0.
Mcc called asking us to fix the beamline ion chambers. This system was installed by Dan Dotson of the accelerator radiation control group. Dan was contacted by mcc, but he thought the problem was not in his equipment . Accelerator AES group changed an ADC board in a crate located in the mcc computer room, but they called us back to verify that we need the ion chambers operational for our run. We confirmed this. It seems that the ioc in which the ion chamber adc resides is historically difficult to reboot. When rebooting, we may regain the ion chambers but lose other accelerator instruments.
