Dear All,
We had a lively discussion at today's EMCAL meeting about how the radiation damage in the SiPMs will affect the noise and our ability to see MIPs in the EMCAL after we start running. While our paper on radiation damage in the SiPMs doesn't answer this question directly, it shows the effect we expect to see in the SiPMs currents as a function of radiation dose, which I think we have now taken as a given. There are also lots of other slides and talks about this subject, but we have not really faced how this will affect the EMCAL calibration and performance, especially after some period of running. I think some simulation of this would be extremely helpful and I would therefore encourage anyone who is interested to join in the discussion and help us understand how we will eventually deal with this problem.

Cheers,
Craig
