CUPID is the “CUORE Upgrade with Particle Identification, a research and development project for the CUORE detector.CUPID aims to use new detector materials in the same cryostat as CUORE.

The Cryogenic Underground Observatory for Rare Events (CUORE) required the ultracleaning of around 5000 Copper parts. The recipee found for the required cleaning consists in the following steps:
1. Preliminary wipe cleaning
2. Ultrasound Cleaning
3. Ultrasound Rinsing
4. Centrifugal Barrel Tumbler
5. Ultrasound Rinsing
6. Electropolishing
7. Rinsing
8. Ultrasound Rinsing
9. Chemical Etching
10. Passivation
11. Ultrasound rinsing
12. Vacuum Cleaning
13. Careful vacuum packaging

ARIES is an Integrating Activity project which aims to develop European particle accelerator infrastructures, co-funded under the European Commission’s Horizon 2020 Research and Innovation programme.


DarkSide-50 at Gran Sasso underground laboratory (LNGS), Italy, is a direct dark matter search experiment based on a liquid argon TPC. DS-50 has completed its first dark matter run using atmospheric argon as target. The detector performances and the results of the first physics run are presented in this proceeding.
