Detailed Description

Service providing the static device detector description.

This service populates the detector description data which does not change during the run and is needed for executing track reconstruction on GPU: traccc digitization config: module segmnentation info used in clustering detray detector: the tracking geometry on the device athena<->acts<->detray ID map

All objects are recorded to detector store as pointers to device objects, apart from the athena<->detray ID map. Additionally the digitization object is stored in detector store as host object, which is needed for EDM conversions.

Being a service, it is initialized before any algorithm in both serial and multi-threaded jobs, so that the objects can be retrieved from the detector store during the initialization of the algorithms. The per-module conditions (eg. lorentz shift) are written by DeviceDetectorDescriptionCondAlg.
