The OPAL Discussion Forum

Hi Nicole

I am a new user of OPAL, and I've been simulating photoinjectors. When I first started it was a great help to look at the PITZ gun file that Steve Russell passed along. 

Great, I hope you had success !

Now, I would like to simulate a thermionic gun. I think making the switch would mainly consist of adjustments to the beam distribution, and of course new field files. I have a good idea of where to start based on chapter 11 of the manual, but it would be great if I could see an example input file. Do you guys know of anyone who has simulated thermionic guns in OPAL? 

No I do not know if anyone simulated a thermionic gun. Would that be a DC gun? What are the parameters? Basically you are right you need to come up with a realistic

beam distribution, OPAL can not simulate the emission process.

Cheers Andreas
