Max Bruker
Previous (Apr 13 - Apr 24)
- We finally know that the profile monitor at IMP does what it should, it just stores the time information wrong
because of a bug in their implementation. I pointed out what they need to do to fix it in case they should need the thing
again, but they don't seem particularly interested. Because it's impossible to infer the correct time scale from the
metadata and the logbook entry doesn't correspond to the data in any physically reasonable way, we are now working under
the assumption that there was a communication error in the control room that caused the logbook entry to be different from
the actual setting, which we in turn infer from the data as we've been proposing for a few months now.
- The results part of the article is close to being finished. I'm sending out the current version today.
- Communications seminar was good.
- APS meeting was good, too, and surprisingly so. Not only because of the circumstances, but also because I'm used to the
German counterpart, which is so appalling that the only reason to ever go there is to drink beer with old friends.

Andrew Hutton
Previous two weeks (Mar 30 - Apr 10)
- A lot of thinking about EIC including a detailed evaluation of the pCDR luminosity optimization (presented at the JLab EIC
meeting). I also continued on my quest to understand coupling. I took part in the RF frequency discussions; I would be
happy if the choice was 400 MHz, but not 394 MHz. Haven’t we learned anything about the advantages of standardization?
- We have made a lot of progress on evaluating the isotope experiment and future design (Joe Gubeli and Keith Welch). I need
to get my act together to collate it all. I had a video conference on PERLE and wrote a brief report to Andrei, Mike and
Todd. I contacted the Chair of the VCU Mechanical Engineering Department who put us in touch with Hooman Tafreshi, their
heat transfer expert. The discussion was not that useful directly, but it did serve as a catalyst for us to start thinking
about the problem of the 50 kW crucible.
- I took Ethics Training because I am on VNECA, which officially advises the Virginia Governor, so every two years I have to
listen to a one hour ethics lesson!
Next two weeks (Apr 13 - Apr 24)
- Continued working on coupling and wrote a presentation to get everything in one place. Dave Douglas was very helpful. I
will continuing this and involve others when it seems reasonable.
- For the isotopes, we had a brainstorming session on the design of a 50 kW target. Some good ideas, but video doesn’t work
as well for brainstorming. I had Dave Meekins on the line, but was not aware of that since you can’t share the screen and
see the participants.
- Isotope Quarterly Report due on Friday, April 24.
