Beam and energy changes continued over the weekend. The ICR reports that things are going swimmingly, and that the users are happy. Scaler counts are up some 30% or so from Tuesday. All good. A source and line touch-up Wednesday (Remembrance Day) morning and a tuning effort following an energy change during the day on Wednesday produced strong and stable beam running.
Attached is a stripchart of the last day or so of running. The thick blue trace is the DRAGON scaler. The fine green trace is a source collimator, representative of total beam from the source and its stability. The spikes are periodic Faraday cup readings. |
