Restart of PSC and APS U Mode 0 and 1 Electrical Work

• Due to recent electrical incidents, upcoming experiments require an additional level of review including walk-downs through the experimental stations before they can be approved to begin.

• These requirements take additional time to perform, therefore users should submit their experimental safety approval forms well ahead of their beam time, and allow for extra time for safety staff to come to the beamline for review.

• Please contact your beamline contact to ensure that everything is on track for your scheduled experiment, particularly for experiments requiring sample preparation before start of actual beam time.

• Questions or concerns should be sent to

User-Supplied Equipment

• Inspections of equipment that require electrical power have resumed. 

• Please consult with your beamline contact if you plan to bring equipment for an experiment, to ensure that it can be safely utilized.
