Gabor Lens meeting: 21May20; 16:00 BST

Present:

Notes

1. Introduction, notes and actions: KL/All
   • JPo: Provide TSD with the geometry of the present prototype Gabor lens
     • Stands. Still seeking the dimensions of the present Gabor lens.
   • KL/RB: Take a look at the Bingham et al paper on laser-driven accelerator for medicine
     • Stands.
   • TSD: Provide beam envelope as a function of distance along the beam line for CW to plot
     • Done.

2. Updates on the calculation of instability: RB
   • With design in hand, RB can prepare a calculation of the instablisities.

3. Electron injection simulations: CW
   • Get electrons on axis by shaping electron emitter.
   • RB: optimise to get electrons on axis to limit diocrotron instability.

4. Updates on the particle generation: HT
   • Dose-rate calculation.
   • Has run a simulation with SMILEI and is now beginning to unpack it

5. ERC proposal timeline: KL/discussion

6. Discussion of plasma simulation code - CST vs VSIM: All
   • Some experience at Strathclyde; CST has recent upgrade.
   • We discuss possible ways forward and conclude that we take a practical approach. Use VSIM from DF for now. Look at CST as we go.
   • TSD thinks VSIM more powerful that CST. So, happy with parallel approach.

7. AoB
   • None.
