Hello,
I have this gps macro file and I want to make some changes and I do not know how.
I would like to have a uniform beam with 65 mm radius. And in that to have to photons with distance between them from 100 microns until 2 cm. So the distance between them to vary from between these two values for each event: 100 microns < d < 2 cm.
How can I define this distance etc?
Can I also have square beam?
Thank you very much in advance!
Whatever help is very much appreciated.
