FLUKA team,

I've read all references to SPECSOUR and SDUM SYNC-RAD that I could find in the manual and release notes. Unfortunately, I can't find any references to SYNC-RAD, which is making it difficult to properly implement the SPECSOUR card. I have a few questions about the following screenshot.

1. I have 2 equal magnitude, opposite direction magnetic fields I wish to see synchrotron radiation from (a turn from +z to +x, and then from +x back to +z, each 90 degrees). Will I need 1 or 2 SPECSOUR cards?

2. Are Bx and By actual field values, or Pythagorean values? i.e. if my entire field for turn one is positive y-axis, does By=1, and then for second field By = -1 or is it By = 0.793388 (Tesla) and negative for field 2?

3. x2, y2, z2: "Coordinates for possible second path". Is this the declaration of the entrance to another magnetic field of same orientation, or something to do with the next step in the electron's track? I don't understand this portion of the card.

4. Cosx2 & cosy2: I think the answer to question 3 will help me understand these entries.


Kindest Regards,
