[Gate-users] How to create this - slant hole in a plate

[Cui, Yonggang]

Thanks, Marc.  What I am looking for is the shape shown below (I hope my sketch is clear):

Hello,

I am not totally sure about the geometry you want to create for the hole but I added the following
volume in Gate v6.2 which is an Elliptical Tube. You might try it and see if it suites your needs.

See the User's guide:
http://wiki.opengatecollaboration.org/index.php/Users_Guide_V6.2:Defining_a_geometry

and

http://geant4.web.cern.ch/geant4/G4UsersDocuments/UsersGuides/ForApplicationDeveloper/html/Detector/geomSolids.html  (G4EllipticalTube)

and

http://mathworld.wolfram.com/CylindricalSegment.html

Don't know if it will help.

As far as I know, this is not possible with the current geometry features of Gate.

However, since Gate is open source, you can add the feature yourself!

If you look at the source code, you'll see that the volumes that Gate supports are Geant4 volumes. A look at the Geant4 source code reveals that it supports many more volumes than Gate. There might be one or more volumes that suit your need in there. You just need to implement it in Gate (using the current source code as a template). It should be relatively straight forward... but your geometry need is a bit complex...

Good luck!
Marc
