We have complete the installation of the Radiabeam Corrector
Magnet in the Injector.
We installed (2) 10 ohm 50w resistors in parallel with the
(2) 15 ohm 25w resistors that were already in the junction
box, to give us a 6 ohm limited resistance on the magnets.
We cycle both MCR2I01H and MCR2I01V magnet and did a
Scott Higgins has updated the software for these magnet in
the CED and EPIC.

Larry and I took the tube from #1 IOT (Pass 2) and replaced
it with the spare. Today we attempted to operate the IOT
but discovered problems with one of IOT 4's two bypass
switchs and problems with loose and damaged wires in the
bypass relay logic. One bad switch is replaced and the
loose wires are fixed. We plan to attempt to operate/test
IOT 1 with the spare tube again on Monday. This test will
not be induce RF into a cavity but into a load.
Just doing a daily check on the Function Generator for the 30hz Switcher System and I found it in a bad state. It looked as if it had been power cycled (viewed from the Expert Screen). I took a ride over to the MCC and took a look at the unit. It was in remote mode but something just did not look right. I turned the GPIB controller off line and then power cycled the Function Generator and set it up manually with 60hz Freg, 0vdc output and Square wave selected for output waveform. I then turned the GPIb controller back on line and waited for the PC104 device to boot up and make connection.
Sam, Leo and I installed the necessary jumpers in the Cross Connects @ 1L07B12 and 1L07B14 equipment raacks to allow RF to be generated in the replacement Cryomodule.
We will continue check out Monday..
It is possible that the diagrams we are using has a typo on one of the locations we will verify tghis Monday.
Thanks Leo and Sam for the help!
CHL Cooling Water Pump Motor 3 requires a replacement of the power cable. Facilities is preparing to repair or replace Pump 4 in addition to replacing cable for Pump Motor 3.
