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.

Previous two weeks (Mar 16 - Mar 27)
- Continued work on the H- intrabeam stripping estimates. Conversion of TRACK output for comparison with PyORBIT estimates.
Both PyORBIT and TRACK outputs indicate that the loss rate due to H- intrabeam stripping in the JLEIC ion linac a couple of
orders of magnitude higher than that in the SNS superconducting linac. This results in integrated power loss of about the
same order, even though the beam power in the JLEIC linac is much lower. Working on checking the calculations because this
seems high, but the power loss rate is still lower than the threshold for which intrabeam stripping losses is considered to
be dangerous.

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 16 - Mar 27)
- The last two weeks have been spent trying to get used to working from home. I think I am getting there!
- For the EIC, I attended two meetings of the RF team, I wasn’t much use. I did spend a fair amount of time to look into the
idea of reducing the vertical emittance in the EIC proton ring, either by emittance exchange or coupling. For the emittance
exchange,I am now certain that the “traditional” method of transverse-longitudinal coupling will not work for 25 GeV
protons. I do believe that a transverse emittance re-distribution might be possible, either in the transfer line or in the
Yellow Ring. Of these, the transfer line would be best. I also think we could look into slow extraction from the AGS
followed by horizontal stacking in the Yellow Ring.
- For the Isotope Program, I have been involved in suggesting directions for calculations which are proceeding well (Joe
Gubeli and Keith Welch, aided and abetted by the NMT students). I have prepared a new set of milestones and sent it round
for comment - so far it is an anechoic chamber out there! I also sent around information on the upcoming FOAs and got a
positive response from Jamal at VCU, but Doug Wells has been offline for weeks. I suspect he has been dragged into
organizing teaching online, a massive task!
- I attended a videoconference on PERLE which is starting up again. I wrote up a brief report fro upper management, with
positive response from Andrei.
- The ALCC is now considering writing a short White Paper to submit to the Snowmass meeting November 4-6, 2020 in Fermilab. I
will probably get involved editing that.
Next two weeks (Mar 30 - Apr 10)
- Continue with EIC work, hopefully collaborating more closely with Dave Douglas.
- I will need to finalize the Isotope Milestones and send them to Ethan Balkin. I also need to write the Isotope Quarterly
Report, due around April 24.
