DS Material meeting minutes 31/08/2021 (L. Luzzi)

- Material verification (Vicente): he reached the relevant people that are responsible of different parts of photoelectronics. Only confirm about the stearing module and optical module, missing information about tile and feb. Let’s discuss this in details next week.

- Neutron budget (Maxim): new information considered about electrical and optical trasmission. Check offline if the latest assays results are included in the bottom left pychart of the Maxim presentation, regarding both electrical and optical trasmission. Let’s discuss this next week.

- Gamma budget (Sam): should interact with Vicente about new information about pdu slim (pdu slim has to be included in the material spreadshit). The original question is if there is a difference between pdu plus and pdu slim, from gamma point of view. We have only information about pdu plus.

- Comment from Alessio: what kind of acrylic can be used for DS, from the radiopurity and purification point of view? For the acrylic we will use the one from Juno line, but it’s not sure for Gd loaded acrylic because of the removing of nano granes. We need to measure some samples protecting them from bulk contamination and surface contamination. Vicente, Bianca and Alessio organize this ship, one to LNGS and one to Kracow to make this measure.

- Next week we will discuss the internal policy of the group.
