IPM1L04 - IF card replaced (https://logbooks.jlab.org/entry/4551346)

Swapped out the IF card for 1L04. Set the jumpers for the correct channel location. Powered up the crate but the last four channels came up as "Hardware Disabled".

After troubleshooting the card and crate, discovered the GIF communication cable was damaged.

Replaced the cable, performed a "check VMIC " and all the BPMs were enabled.

Signal injected the IF directly at 45Mhz at -60dB and -50 dB. Channels looked balanced and the gains looked even.

A great scope walkthrough today with Vince and Dave from the machine shop and Jessica, Marcy, Shukui and me. The job is nominally planned for Monday morning, there will be a PJB for the crew before the job begins. Shukui is managing the WCD's.

We have a good plan, here are some of the remaining pre-jobs:

1. Shukui will work with RadCon to acquire a second rad-vac so we can collect aluminum wall shavings/debris both inside and outside the laser room and will coordinate with Onish to turn off the magnet racks so correctors and solenoids are unpowered.

2.

from Cryo e-mail:
Yesterday, we put 1L07 on a purge rig to start a cleanup flow. We are flowing through the module and will continue to do so until we install U-Tubes for the module cooldown.

SRF has requested to cooldown the module on Monday, November 2nd, which we are able to support. This makes the U-Tube schedule as follows:

Monday 11/2: Install primary supply and both shield U-Tubes (L-Tube for primary return is already installed with purge rig)

Wednesday 11/4: Swap L-Tube for primary return after a successful cooldown and additional soak time
