Notes
Participants: A Kurup, K Long, J Hughes, T Descalu, J Parsons, G Hicks, HT Lau, O Ettlinger, R McLauchlan, W Shields, C Whyte, J Matheson, C Hardiman.
Apologies: J Pasternak, G Schettino.
- Capture -TD
- Looking to simulate the electron cloud in the Gabor lens and look at plasma instabilities. Issue with getting access to the VSIM code on the SCARF cluster.
- KL: do you run VSIM at Strathclyde? CW: Yes.
- CW:
- Now having weekly meetings.
- Document on dimensions of initial design.
- Bob will run some simulations to investigate diocotron instability.
- Will try to look at how an e-beam can be used to fill the lens.
- Simulation
- Stage 1
- TD: replacing solenoid in the BDSIM simulation with Gabor lens fields.
- Implemented transfer matrix and an idealised electric field map in BDSIM.
- Issue with difference between ideal electric field map and the transfer matrix.
- AK: Could this be due to the integrator?
- WS: the matrix integrator will always be used for an r-matrix element.
- HTL
- Want to look at improving the input beam used in tracking simulations., i.e. look at using Smilei.
- TD: replacing solenoid in the BDSIM simulation with Gabor lens fields.
- Laser-target simulations.
- OE: Previous 2D distribution came from a simulation of TNSA using a thin foil using EPOCH.
- OE: Resolution of a 3D simulation will be poor, 2D will be better resolved.
- Discussion on generating 2D versus 3D.
- GH: Documentation in the group to get Smilei up and running. Smilei can output at a different resolution than the simulation which EPOCH can't.
- AK, OE, GH, HTL and TD to continue discussing details of how to proceed after this meeting.
- Space charge
- AK: would be good to investigate GPT algorithms (verify performance) and look at other algorithms/codes.
- HTL: Would like to do this, depends if there's time.
- KL: Is there still a plan to implement space charge in BDSIM?
- WS: Yes but not immediately.
- Stage 1
- AOB
- Publication: deadline for comments is Monday and then will be finalised.
- Future meetings.
- AK: Need to think about other activities that can be progressed given the lockdown situation.
- KL: Radiobiology?
- JPar: Clatterbridge is still in lockdown. Maybe could get back in June.
- Can keep everyone updated on ongoing analysis of previous experiments.
- Discussion on how to coordinate this.
- JPar to email regarding fixing the best time for regular meetings on radiobiology.
- JPar: Clatterbridge is still in lockdown. Maybe could get back in June.
Action items
- AK, OE, GH, HTL and TD to continue discussing details of how to proceed with the laser-target simulations.
- JPar to email regarding fixing the best time for regular meetings on radiobiology.
