Reseated card. Channel looks okay. We will keep an eye on this channel to see if we need to swap card with a ready spare.

While cleaning contacts in the 2L18 interlock panel for the recent HPA Not Ready HV drops, the South Linac was inadvertently dropped to lockdown when a lug came loose, interrupting the off/safe signal. Lug was reinstalled and work stopped until the segment gets back to Power Permit.

33MeV in the NL. Highest I've seen yet this run!
69MeV in the SL.

And I've just been made privy to handy gradient reach over time plotting suite. Thanks Jerone! Figure 2.

According to the suite, 36MeV in the NL and 96MeV in the SL.

36MeV in the NL makes sense if you aren't reserved 4MeV for lock headroom, which Figure 1, i.e. LEM, does.

96 vs 69 MeV in the SL doesn't quite square, however, so examining the suite to ensure its analysis is correct.
