CSR LDRD March 19 2015

Presents

  David Douglas, Alicia Hofler, Yves Roblin, Chris Tennant

Agenda

1. Update on Current Progress
   1. Longitudinal Match and parametric studies (Chris)

1. 1. LDRD budget refactoring (Yves)

We presented the new plan early march at the CASA meeting. The slides are attached. Basically, one will refactor the LDRD to allow for money to be spend to buy

a 96 CPU computer to run extensive GPT simulations for exploring the injector parameters.

Presents:

David Douglas, Alicia Hofler, Yves Roblin, Chris Tennant.

Agenda

1. Status update
   1. Longitudinal match and parametric scans (Chris)
   2. LDRD budget refactoring (Yves)

List of tasks

1. Yves:
   1. Produce spreader/arc match for the “good” and “bad” ARC.
   2. Check with Rui about Cheng Ying availability to calculate microbunching gain
   3. Investigate ability to do transverse tomography in spreader 2nd step and recombiner 2nd step.
2. Chris:
   1. Send the lattices, see whether or not they match the actual ARC1 layout
   2. Extend the parameter scan to higher emittances, incorporate spreader
3. Alicia:
   1. Review the injector simulations, maybe produce longitudinal dt/dp with more points
   2. Transverse phase space parameters for the simulation, which charge was it ?
   3. What is the max charge we can produce with existing setup (laser, etc..) regardless of transport
   4. Send higher charge per bunch simulations of injector to Chris (transverse em., bunchlength,bunch charge, e spread after ¼)
4. Geoff:
   1. Ability of linac to transport short bunch with high charge. What are the limits on either side (short or long)?
5. David
   1. Unearth documents about nuclear physics bypass.
