Question How to define multiple sources intensities from the beam power with GPS

Hello,

I'm simulating a photon shutter on a synchrotron accelerator, and I'm a little stuck on defining multiple sources with GPS.

I have two sources. One is an X-Ray source (100 keV photons) with 200W, and the other source is of bremsstrahlung radiation (3 GeV photons) but with 2.513E-3 W.

My question is how to define both sources in the same run. I tried the following, but not sure on the intensities:

# beam #1

/gps/source/intensity ??

/gps/particle gamma

/gps/ene/type Mono

/gps/ene/mono 100 keV

/gps/pos/type Plane

/gps/pos/shape Rectangle

/gps/pos/rot1 0 0 1

/gps/pos/rot2 0 1 0

/gps/pos/halfx 0.015 mm

/gps/pos/halfy 0.15 mm

/gps/pos/halfz 0.15 mm

/gps/pos/centre 0. 0. 50. cm

/gps/direction 0 0 -1

# beam #2

/gps/source/intensity ??

/gps/particle gamma

/gps/ene/type Mono

/gps/ene/mono 3 GeV

/gps/pos/type Plane

/gps/pos/shape Rectangle

/gps/pos/rot1 0 0 1

/gps/pos/rot2 0 1 0

/gps/pos/halfx 0.015 mm

/gps/pos/halfy 0.15 mm

/gps/pos/halfz 0.15 mm

/gps/pos/centre 0. 0. 50. cm

/gps/direction 0 0 -1

Thanks a lot!
