Accelerator R and D (Y. Zhang)
Computational Physics (Y. Roblin)
- Last week vacation
- Before this:
- working on PRL referee report (submitted today)
- reread articles on gear changing, trying to reproduce Hao Paper with BB3D
- modifying BB3D to do gear changing
- Interviewed candidates for #11807.
- Worked on cooling simulations for DC cooling scenarios where one reuses the b. beam cooler.
- Conclusion is that one can cool after filling the booster at 8GeV. 30 meters of solenoid, 3A of e- current and about 10 minutes of cooling time.
- interview panel for #11807
- working on user interface for JSPEC
- working with summer student.
