Subject: EZL PS replaced. Test 

EZL checked. OK @ 5kV

BIAS PS issues.

2.3kV on screen. Read back on PS 3kV. Direct measurement reads 5.8 kV

Readback does not increase with the controls. Stops at 2.4kV & the current climbs very quickly.

Tuesday, March 26, 2019, 11:00: EZL PS routed to TS BIAS, but still controlled via EZL controls. EZL line grounded.

Brought up to 20kV, no sparks. 

New EZL PS confirmed ok. BIAS PS has issues.
