DS-Mat regular meeting

Tuesday 10 Dec 2019, 16:55 → 18:00 Europe/Rome

Alex, Vicente, Marina Zykova, Roberto, Susana, Tomasz, Bianca, Iza, Jeff, Paolo, Secret Redmi user.

Assays:

Mroz: copper from PCB board 300 mBq/kg temporary result.

This week they will start with next sample.

Susana: nothing to report

Iza: nothing to report.

Gd contamination besides U and Th:

Vicente: Gd elements, other than U and Th have a subdominant contribution.

Alex asks if it means that this Gd is OK for production or further refinement would be requested.

Vicente answers that HPGe and Po measurements are necessary to give an answer to that. With ICPMS values the contribution is subdominant, but that is not a safe assumption. Measurements are needed.

Roberto asks if they can be done and it is said that a Russia-EU agreement on the topic is necessary in advance.

Alex mentions he is discussing this topic with Gemma tomorrow.

AOB:

We agree on having a dedicated cryostat meeting.
Jeff says possible explanations for the different results are under study but no conclusion yet.
Vicente will upload to this page a discussion with Andrea regarding this topic which happened last week.

Roberto says he is in contact with Mark Boulay to arrange a date for a surface contamination meeting
