Dear All,


Thank you for your kind assistance with this. Chuan, I will be reinstalling OPAL-1.6 on a fresh install of SL7 in a VirtualBox. If there is a different distribution that I should use, let me know. Enjoy your trip!


Thank you again, Andreas and Christof for referring me to others who can help.

Dear Cantwell
I am on a trip now and I will look into the problem in the weekend.
As said by Dr. Andreas, version 1.6 is the latest version that contains the multipacting mode.
Best regards

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?
