[Gate-users] Curved Scanner for CT simulation

[Karl Spuhler]

Hello fellow GATErs,

I am in the process of writing some CT simulations and the examples all
make use of flat panel detectors. My group is interested in geometries
utilizing curved detectors. I am having trouble finding support for this
feature but have written the following, I was just generally wondering if
anyone has any recommendations for improvements:


/gate/world/daughters/name CTscanner
/gate/world/daughters/insert cylinder
/gate/CTscanner/setMaterial Air
/gate/CTscanner/geometry/setRmax 80 cm
/gate/CTscanner/geometry/setRmin 79 cm
/gate/CTscanner/geometry/setHeight 15 cm
/gate/CTscanner/geometry/setPhiStart 65 deg
/gate/CTscanner/geometry/setDeltaPhi 50 deg
/gate/CTscanner/placement/setTranslation 0 0 -40 cm
/gate/CTscanner/vis/forceSolid
/gate/CTscanner/vis/setVisible 0

/gate/CTscanner/daughters/name module
/gate/CTscanner/daughters/insert cylinder
/gate/module/setMaterial Air
/gate/module/geometry/setRmax 80 cm
/gate/module/geometry/setRmin 79 cm
/gate/module/geometry/setHeight 15 cm
/gate/module/geometry/setPhiStart 65 deg
/gate/module/geometry/setDeltaPhi 50 deg
/gate/module/placement/setTranslation 0 0 -40 cm
/gate/module/vis/forceSolid
/gate/module/vis/setVisible 0

/gate/module/daughters/name cluster
/gate/module/daughters/insert cylinder
/gate/cluster/setMaterial Air
/gate/cluster/geometry/setRmax 80 cm
/gate/cluster/geometry/setRmin 79 cm
/gate/cluster/geometry/setHeight 15 cm
/gate/cluster/geometry/setPhiStart 0 deg
/gate/cluster/geometry/setDeltaPhi 0.25 deg
/gate/cluster/placement/setTranslation 0 0 -40 cm
/gate/cluster/vis/forceSolid
/gate/cluster/vis/setVisible 0

/gate/cluster/daughters/name pixel
/gate/cluster/daughters/insert cylinder
/gate/pixel/setMaterial Lead
/gate/pixel/geometry/setRmax 80 cm
/gate/pixel/geometry/setRmin 79 cm
/gate/pixel/geometry/setHeight 0.1 cm
/gate/pixel/geometry/setPhiStart 0 deg
/gate/pixel/geometry/setDeltaPhi 0.25 deg
/gate/pixel/placement/setTranslation 0 0 -40 cm
/gate/pixel/vis/setColor cyan
/gate/pixel/vis/forceSolid


# REPEAT MODULE
/gate/module/repeaters/insert ring
/gate/module/ring/setFirstAngle 65 deg
/gate/module/ring/setAngularSpan 50 deg
/gate/module/ring/setRepeatNumber 190

# ATTACH TO SYSTEM
/gate/systems/CTscanner/pixel_0/attach pixel

# ATTACH LAYER
/gate/pixel/attachCrystalSD
