Dispersion worsens between 14 and 15 July, C and D lasers

1 day 5 hours ago
Log Number: 4528891Logbook(s): Entry Makers: kpriceBody: 

Comparing FOpts a little under a day apart, it looks like large differences in dispersion surface between C and D lasers. Differences start as early as 1L, becoming significant by 2S -> 2A. We don't have a good comparison of FOpts between C and D since the C pass change so differences are a bit difficult to track down. Either way, vertical dispersion is well out of spec by 2R.

Hall C limited to 55 uA from BLA trips

Working on finding what is causing the issue, it may be coming from early on in the machine. Loss on IDX is different than it was yesterday. At the moment we will try to find the cause of the loss rather than do another BLA cal.
