CLS extends shutdown to repair electron gun…

July 30, 2018

On June 27, the facility's electron source failed, resulting in loss of beam. Several malfunctioning components were identified in the main electron gun’s power supply. After initial repairs, CLS staff members determined that the power supply’s transformer needed to be replaced. We regret the impact this outage will have on affected projects, and CLS staff are doing everything possible to resolve the problem. In order to complete the repairs, the CLS has had to cancel user shifts until November. Additionally, the CLS will not be opening the August call for new proposals.
