Sos: If everything goes fine, we should have the SoS licenses soon at UPC and then we will crete the SoS server to share the blocs.

Reusage of Blocks from FastIC. We had an informal conversation with CERN. They agreed to reuse FASTIC blocks for CTA, i.e., for research purposes. For commercialization, the reusage of blocks can be possible, but it needs a separate agreement.

Front-End behaves linearly for 250 PE, the problem lies in the TIA that the FASTIC version only allowed a maximum of 1 mA. The HF still needs optimization for this particular sensor.

Luca did an study of the impact of the Rq onthe recovery time of the SiPM. Excessive Rq causes excessive recovery time i the same microcell and then a second event loses amplitude.

NSB is expected to be between 250MHz-500MHz. NSB coms from stars, mooon, reflectios lights from streets, etc. For instance, for 300MHz. If we expect a FWHM of 3 ns, we will expect one PE every 3 ns. If this is a Poisson distribution, some of them will pile up.
