MCC operators delivered 10uA unrastered beam on our dummy Al target for about 2 or 3 minutes! According to the target spec sheet, this target requires a rastered beam at all times. We need this target this evening for our background measurements. This type of operator error is unacceptable under any circumstances. Our shift leader told the operator we were doing a raster size check and asked for 10uA. MCC operators need to refer to the target spec sheet at all times for safe delivery of beam to target.
