Hi Wei Hou,

I cannot help with you reference particle question, but a comparison between OPAL, ASTRA and GPT using the AWA photoinjector was done a couple of years ago and the agreement was good.  See Nicole Neveu's conference paper:

Subject: [Opal] Reference particle in OPAL
 
Dear OPAL developers,

This is Wei Hou TAN, graduate student working with Prof. Philippe Piot in the Northern Illinois University.

I would like to learn OPAL, starting by cross-checking its results with ASTRA.

In my toy example, I simulated a rf gun with both ASTRA and OPAL.
However, I am having problems getting same results in OPAL.
I have checked that both ASTRA and OPAL have the same distributions, same RF phase.

I suspected that OPAL has a different definition of reference particle but I could not find any documentations on it.

What is OPAL convention of reference particle ?

Thank you.

Regards
Wei Hou
