Assistents: Diego, Pep, Xavi, Rafel, Oscar

Rafel fixed the SiPM model and now behaves linearly. 

He is improving the PSRR of the front End stage

Oscar pointed out if we are considering the NSB (moon light) and light flashes, for instance, from cars. For the first case, maybe 100 photons canbe generated. For the latter, thousands over a few seconds. We need to discuss these specifications for the design of the Front-End and for the slow intgrator.

A time constant of the slow integrator couldbe around 1 ms.

It would be good to have values of the expected performance of the sensor in these conditionc (NSB and fast light flasehes). We need to ask Ginebra what they did in this sense. WE could study the sensor behavior (and level of current) using the PACTA ASIC
