SSG will perform this task on Tuesday 11/2/2026.

A planned repair of this Credited Control device was screen through Safety Concern Form SC-2026-1102.

Even though we don't anticipate a need to remove credited shielding surrounding this component, we've contacted RadCon informing them about SSG work near the shielding.

The permit is on issue.

Important items are staged.

Tomorrow's work will focus solely on removing the current amplifier installed in the rack (this is the one SRF lent to us). No one will be running RF in the SL for the next few weeks, and the work on Friday Nov 6 will take the MO down (sitewide) anyway.

Once (and while) the amplifier is out (over the next few weeks), RF will coordinate measurements we cannot perform with the system in its normal state.
