The Power Calculator is used to determine the Power, Current, or Energy given the other two (and the Duty Factor). When using it for the Injector, one works in W & keV. I've found that when inputting a leading decimal point, it is ignored, which leads to an erroneous answer. (If one enters a leading 0 first, or adds a leading decimal point after entering a number, it works.)

In today's first ramp up cycle we noticed HVPS current baseline increased at 206 kV, and went back to normal level during ramp down at 100 kV. In the 2nd ramp up cycle we noticed the onset of baseline shift appeared earlier at 140 kV. This indicates some current leakage in air side. Next, we will inspect the gun HV ceramic and the cable joint, and also remove the resistor tank and inspect the joints. After reconnection of gun HV cable, we will continue evaluation.

L-Tubes were removed from 1L06 and 1L07 return transferline locations. Guard vacuum connection was disconnected from 1L06.

1L06 RT valve motor was found spinning. This is likely an issue with the belt (stripped, broken). This will be repaired before PR U-Tubes are installed.

No other issues were encountered.

Work completed for now. Rotated the polarizer back to a horizontal polarization orientation. Check the optics and found both the inseratable mirror and window coating strip off in a band. This is caused by high energy synchrotron radiation. This was anticipated and will not fundamentally change how the SRI operates.
