- Coordinate JLEIC impedance meeting: good progress in the IR chamber design (Mark wiseman)
and EM modeling (Frank Marhauser), and heated discussion about Gunn Tae Park's presentation
about harmonic kicker impedance analysis. Also interesting discussion with Dan Wang of LBL
who participated the meeting via bluejeans
- Literature studies on impedance theories
- Family vacation for most of the 2nd week
Next two weeks (May 20 - May 31)
- Impedance studies
- Bunch spectrum for JLEIC bunch pattern and its impact on coupled bunch instabilities
- CSR effect studies (Georg Haffstaetter visit to discuss CSR effects in CBETA)

- Completed IPAC2019-poster and submitted paper.
- "CASA BeamBeam"
- Revised, optimized and accelerated “Crab Kick” of “CASA BeamBeam” codes by using the High Performance Python Compiler,
Numba. Based on JIT(Just in Time), Numba translates part of our “Crab Kick” Python functions to optimized machine code
at runtime using the industry-standard LLVM compiler library.
- Performance of “Crab kicking”
- Simulations have been down for the JLEIC parameters again. For example, for the case CM Energy 21.9GeV, comparing with
previous job, the “Numba” based “Crab Kick” codes can save 1/5 time than the old code for 4000 turn in a collider ring.
- 3 Particles Spin Tracking
- For Snakes 0o, 3 particles spin tracking was carried out again via revised “CASA BeamBeam”.
Next two weeks (May 20 - May 31)
- pyFMM will be under investigation.
- Continue spin tracking study.
