[Gate-users] How to define a Sodium 22 source.

[J.J.M. Kouwenberg]

Dear Andrea,

If the energy type of your isotope is not in the preset list, you'll have the define the energy spectrum of the positron yourself.
Below an example of my Galium 68 source:

/gate/source/addSource G68
/gate/source/G68/gps/particle e+
/gate/source/G68/gps/energytype Arb
/gate/source/G68/setActivity 1000000 becquerel

/gate/source/G68/gps/histname arb
/gate/source/G68/gps/emin 0.0 MeV
/gate/source/G68/gps/emax 2.921 MeV
#                                 MeV      Yield
/gate/source/G68/gps/histpoint    0.00     0.00
/gate/source/G68/gps/histpoint    .1947    0.0351
/gate/source/G68/gps/histpoint    .3895    0.0588
/gate/source/G68/gps/histpoint    .5842    0.0797
/gate/source/G68/gps/histpoint    .7789    0.0964
/gate/source/G68/gps/histpoint    .9737    0.1079
/gate/source/G68/gps/histpoint    1.168    0.1134
/gate/source/G68/gps/histpoint    1.363    0.1127
/gate/source/G68/gps/histpoint    1.558    0.1059
/gate/source/G68/gps/histpoint    1.753    0.0936
/gate/source/G68/gps/histpoint    1.947    0.0770
/gate/source/G68/gps/histpoint    2.142    0.0576
/gate/source/G68/gps/histpoint    2.337    0.0374
/gate/source/G68/gps/histpoint    2.532    0.0190
/gate/source/G68/gps/histpoint    2.726    0.0054
/gate/source/G68/gps/arbint Lin

Subject: [Gate-users] How to define a Sodium 22 source.

Hi all, I want to define a Sodium 22 (positron emission) source.

This is my code:

/gate/source/addSource Sodium
/gate/source/Sodium/setActivity 10000 becquerel

/gate/source/Sodium/gps/particle e+
/gate/source/Sodium/setForcedUnstableFlag true
/gate/source/Sodium/setForcedHalfLife 82078747.2 s
/gate/source/Sodium/gps/energytype Sodium22


/gate/source/Sodium/gps/type Plane
/gate/source/Sodium/gps/shape Circle
/gate/source/Sodium/gps/radius 0.5 mm
/gate/source/Sodium/gps/angtype iso
/gate/source/Sodium/gps/centre 0. 0. 0. cm



/gate/source/list



Is that correct?

Thank you!
