This example describes a rf-photo injector, as part of the Argonne Wakefield Accelerator (AWA). The model based on the paper by N.R. Neveu et al., and benchmarks three codes: GPT, ASTRA and OPAL.

Goal

Here we will run the rf-photo injector (OPAL_t)

Preparation

If you do not have already access to OPAL, you can visit the download page. In case OPAL is on your cluster please check with the administrator how to use. PSI user please click here.

Needed Input Files

For this project we need input files, that you obtain by clicking on links below:

1. Inputfile RFphotoinjector.in
2. Two solenoid field maps: M_440.T7 and BF_550.T7
3. RF gun field map DriveGun.T7

Run the Photo Injector Simulation

For this calculation the initial conditions are all set in the input file. Run OPAL with

opal RFphotoinjector.in | tee RFphotoinjector.out

For postprocessing visit here. The results for the case with a 32^3 mesh and 1E5 macro particles are shown in the following figures:
