Hi Tom I am forwarding this to the OPAL mailing list. Can you also add a fully working example?

Cheers A

Subject: OPAL treatment of travelling wave structures

Date: 20 September 2022 at 11:02:52 CEST

To: "Adelmann Andreas (PSI)" <andreas.adelmann AT psi.ch>

Dear Andy,

 

I am looking at the OPAL manual at the section of the travelling wave structures: http://amas.web.psi.ch/opal/Documentation/master/OPAL_Manual.html#sec.elements.travelingwave

 

Using this method we achieve a nice TWS field however on the edges of the fringe field and middle cells we have a discontinuity which needs to be smoothed for the derivatives. May I ask how this is smoothed inside OPAL?

 

Best,

Tom
