Description

Signal reduction is the most important radiation damage effect on performance
of silicon tracking detectors in ATLAS. Adjusting sensor bias voltage and
detection threshold can help in mitigating the effects but it
is important to have simulated data that reproduce the evolution of
performance with the accumulation of luminosity, hence fluence.
ATLAS collaboration developed and implemented an algorithm that reproduces
signal loss and changes in Lorentz angle due to radiation damage. This algorithm
is now the default for Run3
simulated events. In this talk the algorithm will be briefly presented and results
compared to first Run3 collision data.
For the high-luminosity phase of LHC (HL-LHC) a faster algorithm is necessary
since the increase of collision, event, track and hit rate imposes stringent
constraints on the computing resources that can be allocated for this purpose.
The philosophy of the new algorithm will be presented and the strategy on how
to implement it and the needed ingredients will be discussed.
