Hi Cantwell

The multipacting mode is only available in OPAl 1.6. So after cloning the master,
change to the 1.6 tag with:

% git checkout OPAL-1.6

Chuang Wang in the cc can help you to get the parallel plate test running. This is 
First thing you should do, the results are documented in 1208.6577 . We are about 
to finalise this paper.

For running something like:, you would need to have a geometry. Also here Chuan is 
The right person to ask.

Dear Cantwell, 

I haven't ever used the multipacting feature of opal and I don't know in what state the relevant code is. Unfortunately I also don't have the time to look into it in depth: I work for a funding agency and I can't work on opal during office hours. 

I hope Andreas and Achim can help you with your problem.

Dear Christof,


My name is Cantwell Carson and I am hoping you can help me.


We are making multipaction suppression coatings and I want to create the multipaction susceptibility zone maps for V vs I would like to use OPAL but am having trouble compiling OPAL and running the demo. I have installed OPAL 1.6, but this is incompatible with the 1.9 code on master branch. I have been using a virtualbox and installing opal on SL7 and will try installing the opal nightly on a clean install. This would be the latest in several tries to get the simulation working, and I thought I would ask you for any advice that you might have.


Could you help me get the simulation running on OPAL 1.9 on a clean installation of SL7?
