Max Bruker
Previous (Jan 20 - Jan 31)
- DC cooler discussion at Fermilab
- For results & outlook, see tech note: JLAB-TN-20-003
- Continued analysis of IMP experiment
- It seems we finally agree on the transverse profile monitor time scale; awaiting confirmation from IMP. We probably have 400 ms of
transverse data during cooling, which is not nothing but not optimal either.
- Tried out different sample-based and fitting-based models to extract trends from transverse and longitudinal data. The methods
work but have been giving somewhat inconsistent results so far.

- Longitudinal Schottky signal analysis for December 2019 IMP bunched beam cooling experiments. Evaluating the full width at half maximum
of the central peak in the beam spectrum over the 2 seconds during which the pulsed electron beam is cooling the ion beam. This analysis
resulted in the conclusion that the resolution of the data is not sufficient to estimate the cooling time.

Andrew Hutton
Previous two weeks (Jan 20 - Jan 31)
- After months of effort, Steve Benson, Joe Gubeli, Kevin Jordan, Keith Welch and I finally got Beam Authorization for the 1X line. This
was immediately followed by the discovery that the FL02 cryomodule was producing virtually no gradient (stuck tuners) so we had to
postpone our first isotope production run for two weeks to allow the module to be warned up. This was immediately followed by the
announcement by MCV that Jamal has to quit his lab in the hospital and decamp to the university. This means that his hot cell will be
out of action for months. Decidedly, someone up there doesn’t love me!
- I received an email from Jehanne indicating her desire that the LERF become an isotope Production Facility. I sought guidance from
Stuart and have spent time seeking out a commercial accelerator that would do the job cheaper and better. Apparently, the new, high
energy Rhodotron costs $7M as a turnkey accelerator.
- And I have also been peripherally involved in the discussions on our EIC future.
Next two weeks (Feb 3 - Feb 14)
- The Module is being warmed up in the FEL, tuners appear to be unstuck.
- I have spent this week looking into ferrite tuning for the harmonic kicker, which has morphed into looking into in situ plasma
processing of the CEBAF cryomodules; all of this with Max and Sarah.
- I have also been participating in the discussions on the Engineering White Paper, rewriting the “ask” so that we actually ask for
something!
- Next week, I will be continuing with tuners, plasma cleaning, and EIC.
