2. Issues: BPM got tuned at 9 AM. Then beam went down for 4 hours to fix the Hall B/C seprator. beam back around 13:30 PM totally bad. Extremly high counts on the US halo counter. Contacted MCC and then found that the seprator had issues that might caused the high rates. magnet power supply problem on the accelrator.
