DS Material Weekly Meeting (L. Luzzi)
Minutes

- Status of the assay campaign
1. Chris got samples from indaloi, they will prepare samples of the indium.com solder paste for well counting on Wednesday this week; 
2. Matias got resistors to be screened soon in Germanium; 
3. Chip quick solder paste result to be updated; 
4. No news from Kracow;
5. Iza shipped samples to Kracow and or today or tomorrow they will receive them;
6. Chip quick solder paste already sreened at LSC;
7. Veto samples: one from LNGS and one from china. The chinese one already screened at LNGS, the italian one already screened and it is in the database.


- Rn and Surface contamination paper : Skeleton
We postpone this point to the next week (Grzegorz didn't attend the meeting).


- Status of papers / internal notes
1. Maxim, (alpha, n) note: still in progress;
2. Igor: specify the type of background considered in the note, add abstranct and conclusions;
3. Daria: no news about (gamma, n) note. But simulation for (gamma, n) was made with the Plan A geometry and not with the plan C one, so the simulation was corrected and the note updated. Let’s talk about this next week.


- Gosia, uncertainty yield: updated the table with the composition of materials. Let’s discuss it next week.
