This cavity was restored on 04/21/2026 with CWVF and KRRP onset at 11.8 Mv/m so I lowered the ODVH to 10 Mv/m and it was having problems after 4 days and GSET 0 by the operator who stated a Large Detune Angle when trying to OLT it. Going to set the ODVH to 6 Mv/m and try to recover it as soon as we are back into Permit to try RF again. Leave GSET 0 until RF can look at it and restore.
