David Douglas
Previous two weeks (Oct 30-Nov 10)
- At Daresbury and in UK for entire two weeks
- Talks on Overview of ERLs and tech challenges,
tutorial on magnetized beam transport, seminar on PERLE at
University of Liverpool
- Worked with Peter Williams on SRF linac/SRF-ERL architectures;
generated draft accelerator (top level) requirements for a
system with numerous potential applications. Thought a bit
about implications of ISR on compressors in such systems.
- Came up with a way to make a GERBAL symmetrical, shorter, and
use the same spreader/recombiner at all four corners. Yes,
that's a "symmetric asymmetrical linac".
- Worked through an example calculation with Kirsten showing
details on what happens to a magnetized beam if you apply a
solenoid to it. Writing it up.
- Got information about CSR modeling at magnet transitions
("CSRdrift", in Elegant) suggesting some aspects of this
Elegant feature (Stupakov model) may require caution when used
and interpreted. Communicated this to Chris, who I think will
probably talk to Rui.
Next two weeks (Nov 13-Nov 24)
- More of the same in Daresbury
- Return to JLab, pick back up on cooler design work and follow
up on Daresbury connections
Rui Li
Previous two weeks (Oct 30-Nov 10)
- Organized joint impedance meeting with RF, engineer people and
Kirsten (gaining momentum)
- Meeting with Salvador on coupled bunch instability issues
- Continue with thesis committee organization work (with APS
complications)
- Reviewing fundamentals in impedance theories for baseline discussions
- Participate Bas’s seminar and discussion session about GPT CSR
- e-cooler design meetings
- EIC seminar and R&D meeting
Next two weeks (Nov 13-Nov 24)
- Start reviewing thesis one by one (5 thesis are to be read
through and given scores, and I plan to distribute the thesis
reading time over the next two month)
- Continue with going over impedance theories, simulation and
impedance budget studies in existing machines, and start to
prepare slides for the next impedance meeting
Ed Nissen
Previous two weeks (Oct 30-Nov 10)
- JLEIC: Compile gear-change experiment ideas, give presentation
RHIC and DESIREE seem to be reasonable options, following up with
RHIC personnel with Jiquan Guo
- JLEIC: Reading up on Booster design history, negative momentum
compaction lattices and related nonlinear dispersion issues
Next two weeks (Nov 13-Nov 24)
- JLEIC: Determine feasibility of negative momentum compaction
nonlinear dispersion correction, start redesigning Booster with
new cells and to accommodate new top energy
Chris Tennant
Previous two weeks (Oct 30-Nov 10)
- GPT immersion therapy (Bas visit)
- Bmad parameter scans (running CCR arc, varying CSR code-related
quantities, shielding height, #particles, etc.)
- elegant parameter scans (turns out one of elegant's csrdrift
models may have a sign error, using other models, doing
multi-turn tracking)
- retrieving data from old (broken) laptop HD and backing up
current data!
Next two weeks (Nov 13-Nov 24)
- continue with analysis of CCR simple arc and summarize results
in TN
