Jan 13 2017JLEIC Ion Integration Meeting
Parameter Updates
- Yuhong presented a strong cooling parameter update at the Jan 12 2017 JLEIC R&D Meeting.
- This included some substantial impacts on a broad set of parameters for JLEIC.
- Rui is also starting to develop a work and priority plan for impedances/instabilities this calendar year.
- Discuss and set out objectives for next few months:
- Parameter updates at the baseline parameters wiki page
- Include derived quantity spreadsheets for input to impedances/instabilities, c.f. ion linac parameters spreadsheet.
- These can be placeholders/skeletons as we start filling in things, but will identify parameters that we need to define.
Ion Source R&D at LBNL
- Mike was at LBNL for an 88-inch cyclotron ops review this past week
- Link to review slides etc.
- One item worth noting is their ECRIS ion source R&D for VENUS and MARS.
- We will briefly discuss any possible implications. Note that Amy came to us from LBL!
AOB
- Last meeting we noted: Yves is working with Rui and others to start developing an impedance budget -- progress?
- This partly uses ZAP for some calculations, but some calculations (e.g. IR region beampipe) require calculations with approximate expected geometry.
- Todd is also concerned about BPM designs for the collider ring with long and short bunches (before and after splitting).
- Vasiliy noted that Roman Pots in the ion collider ring at <math>\approx 10\sigma</math> may also have significant impedance impact.
- Tim notes that an engineering team is starting to assemble to evaluate integration needs, e.g. power supply/magnets. BPM and instrumentation design may be part of this.
