Detailed Description

Class to hold geometrical description of a silicon detector element. A detector element is a module in the pixels and one side of a module in the SCT. This class is shared between the Pixel and SCT detector since there is a lot of commonality. It inherits frm ReadoutGeometryBase/SolidStateDetectorElement, which is also used for HGTD

Coordinate Frames.

The following coordinate frames are used in these elements.

Directions of these correspond to the physical wafer. Consequently hitDepth and hitPhi axes go in different directions depending on the orientation of the module. The readout side is determined from design()->readoutSide().

The directions of the axes are defined as

Overview of Methods

Methods are grouped into the the following categories

Author
Grant Gorfine
  • modified & maintained: Nick Styles, Andreas Salzburger
  • modified Nigel Hessey: get directions from the design instead of hard-wiring them
Some notes on Thread safety for AthenaMT

The private methods of this class do not have locks.

The method updateCache of is of particular interest as it set all cache values.

The const methods call updateCache() when they need to perform lazy initialization

if (!m_cache.isValid()) updateCache();

So as concurrent const operations are valid

The non-const methods can set the state of the cache or the cache itself (invalidate/setCache methods etc)

Note: Synchronisation of creating SiDetElements for different events and accessing for each events can be done via write/read handles or similar EventContext aware framework machinery.
