Max Bruker
Previous (Mar 16 - Mar 27)
- Started writing the PRAB article about the IMP experiment. Some questions are still unresolved, but the quality of the
results is starting to look convincing nonetheless.
- Remotely attended the first UITF training session
Next (Mar 30 - Apr 10)
- Continue and hopefully finish my part of the article. There is not much left to do as far as the longitudinal and transverse
profile data are concerned, but I'd like to understand what happens to the synchrotron frequency. Also, I'm getting the
impression that nobody quite knows what our objective/conclusion is supposed to be. I hope we'll figure it out along the
way.
- Attend more UITF training and hopefully the communication seminar that keeps being postponed.

Joe Gubeli
Previous two weeks (Mar 16 - Mar 27)
- Isotope Experiment –Ran several thermal analysis of both the solid hBN and graphite blocks using a FLUKA power distribution
from Keith W. The analysis results showed that graphite is by far a much better material to use to from a thermal as well as
electrical standpoint. The thermal distribution additionally showed that the side cooling plates need to be extended. Ran
five additional analysis of a gallium filled graphite crucible at both 1kW and 5kW with various thermal contact resistances.
These analysis used FLUKA power distributions as inputs. Unfortunately the geometry used in the FLUKA simulations were
incorrect and the both the FLUKA and my thermal analysis will need to be redone. I sent the correct geometry to Keith W.
- Halo monitor – A new CRADA was sent to Radiabeam for signatures.
- ARDDOT –Completed the initial mechanical design of a new SLM for 1A09. This design will be loaded into ZEMAX for
verification of the correct optical design.
- HPWS -A NCE contract was sent to Radiabeam for signatures that will move the end date of the CRADA to September 30th due to
the CODVID-19 telework.
Next two weeks (Mar 30 - Apr 10)
- ARDDOT –Verify the optics of the new SLM1A09 mechanical design using a non-sequential Zemax model.
- Isotope Experiment -Use the corrected geometry FLUKA results of the absorbed power as well as a new raft side plate design
to create several thermal analysis of the gallium filled graphite crucible. Work with Kevin J. on a the extended side plate
design.

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.
