Checklist for GPT/IBSimu simulations and benchmarking ionization routine
Done
- Centering electron bunch through 1.5m
- Ion production rate benchmarked
- Using Maxwellian distribution for ion energies
- GPT writeremove custom element: outputs data for particles that leave the simulation - can be plotted using Mathematica to see where electrons/ions hit the beampipe, e.g.
In Progress
- Space charge routine benchmarked against analytical theory for GPT simulations (works specifically for spacecharge3D routine)
- DC and bunched e-beam simulations
- Benchmarking secondary electron production
To Be Done
- Create (simple) simulation for benchmarking using everything (ionization, gun E-field, real B-field values, vacuum conditions, same initial distribution, etc.)
- For GPT:
- Use local vacuum data in ionization routine (instead of assuming constant gas density)
- Derive approximation for SEDCS for gas species other than H2 and He
