COMMENT ON CMTF forward and reflected kpower calibration
Continuing calibration of the system found 5Vdc power distribution box had been impacted by the LCW leak from the nearby Waster Port Load. This caused a loss of power to 5 RF Sensors. Box has been removed and taken to the Fab Shop for repair. All 4 Klystrons DC trip level parameters have been calibrated. Techs: D. Gelhaar, T. Davis and S. Holben

COMMENT ON Remove/reinstall Injector bpms 2I01 thru 0I02 in support of Injector Upgrade for 2020 SAD
This beam line configuration has had many bpm name changes for the New
Injector beamline. Here are the Injector bpm names starting at the beginning
of the injector and ending at IPM0I05: 2I00, 2I00A, 2I01A, 1I02, 1I03, 1I04,
1I05, 1I07, 0I01 and 0I01B. All the SEE bpm RF modules for these bpms have
been retested and adjusted in my office. Today I returned these modules back
downstairs in the Injector to their almost original locations but with new
names.
