SCT Module geometry using GeoModel

1
SCT Module geometry using GeoModel

• SCT Module geometry is made up of 16 elements.
• A passive volume inherits a class named
  SCT_ShardComponent.
• A sensitive volume inherits a class named
  SCT_UniqueComponent.

2
Structure of the geometry

• This geometry is divided into 3 components.
• SCT_InnerSide and SCT_OuterSide inherit
  SCT_UniqueComponent.
• SCT_DetailBaseBoard inherits SCT_SharedComponet.

3
Structure of the geometry(2)

• A class named SCT_OuterSide group the elements
  like Sensor, ABCDChip, e.t.cThis class is
  defined complex shape that is made of air.
• These complex shape is made by boolean volume.
• The boolean volume makes a complex shape with
  subtracting a box or a tube or adding a box or a
  tube.
• SCT_InnerSide is made by the same way.

4
Structure of the geometry(3)

• SCT_DetailBaseBoard includes elements named
  SCT_FarendFacing and SCT_CoolendFacing.
• SCT_DetailBaseBoard is made up of 5 elements.

5
Dimensions and Coordinates

• We gave all dimensions and coordinates names.
• We calculate those coordinates with minimum
  geometry information.
• We avoid that code has magic numbers.

6
Dimensions and Coordinates(2)

• For example, an coordinate of an element named
  bb2 that makes up SCT_DetailBaseBoard is
  calculated follows bb2PosZ bb1PosZ
  0.5l_bb1 0.5l_bb2, where
  l_bb1 is length of bb1, l_bb2 is length of bb2.
