The OPAL Discussion Forum

["Adelmann Andreas (PSI)" <andreas.adelmann AT psi.ch>]

Hello Simon, in case your particle exits the domain where, the field is

defined by the map, OPAL will throw an exception.

I myself set the length on the element to the length of the field map,

no sure if we have a diagnostic that checks the consistency. 

Cheers A

Dear OPAL-team,

(I hope, I did not overlooked the answer to that question it in the manual. If so, I am sorry!)

If I load an external fieldmap, e.g. for a solenoid.
Are the element options "APERTURE" and "LENGTH" affected by the dimensions of the fieldmap or vice versa?
E.g. the fieldmap extends from 0 to 0.1 and I say L=0.05.
Or: APERTURE="circle(0.02)" and the 2D-fieldmap goes from r=0 to 0.002
[All dimensions in meter]

Best regards
Simon
