[Gate-users] Gaussian Beam

[zahra ahmadi]

Hello every one

I want to define a Gaussian sourcein my program. When I add the comments related to the Gaussian beam:

/gate/source/ positron/setSigmaX              3.0 mm

/gate/source/ positron/setSigmaY              3.0mm

 

 I have an error: 

Comments not found

 

This is my defined source:

/gate/source/addSource                                         positron

/gate/source/ positron/gps/particle                              e+

/gate/source/ positron/gps/energytypeUserSpectrum

/gate/source/ positron/gps/setSpectrumFile                      Spectrum.txt

/gate/source/ positron/setActivity                               100 becquerel

/gate/source/ positron/setForcedUnstableFlag                     true

/gate/source/ positron/setForcedHalfLife                         11 s

/gate/source/ positron/gps/angtype                               iso

/gate/source/ positron/gps/shape  Cylinder

/gate/source/ positron/setSigmaX              3.0 mm

/gate/source/ positron/setSigmaY              3.0mm

/gate/source/ positron/gps/halfz0.25 mm

/gate/source/ positron/gps/radius  0.0 mm

/gate/source/ positron/gps/centre           0.0 0.0 0.0 mm 

/gate/source/list

 

 

Thank you in advance
