Description

(30' talk + 10' discussion)
Items:
- oVTX layout: L4,5,6 ladder design, fixing to the cones with sliding mechanism;
- Mechanical characterisation of the new L6 prototypes. How to cope with starting deformation: thermal cycles by INFN-Pi and cold-glueing by the company;
- thermal-fluid-dynamic bench with not-uniform heathers for 1-pipe cold plate and thermal simulations;
- oVTX cooling needs (Alice experience on the cooling plant: no water-leak sensor!).
