VL04 Replaced RF module
HL10 Replaced RF module
HL11 Found jumpers and no connection to BPMsVL11 Found jumpers and no connection to BPMs
HL12 Replaced RF module
HS12 New BPM , Replaced RF module, Changed gain and offset on frontendVS12 New BPM , Replaced RF module, Changed gain and offset on frontend
HS23 It still has issue.
BPMs which didn’t work after shutdown

Aperture scan analysis: offline to online
*Comparison has to be done with two software.

Plan
Redo scans at 20 – 23.
Measure beam size with MW.
Fix BPM HS23.
Move magnet
