Cooling manifolds

Disk 0 manifolds fabrication is not finished

All manifolds for disk 1 and disk 2 are fabricated, the As and Bs for disk 3 are fabricated as well. Disk 2, outlet manifolds A, B, C and D are cleaned by 31st May 2023.

Working schedule of Pranati and Ali:

- Thursday 15th: first pair of inlet manifolds, aka disk 2 inlet manifolds A and B. Then all EC1 disk 2 manifolds would be ready. And change to disk 1 inlet manifolds A and B.

- Friday 16th: move on to disk 1 outlet manifolds A and B. Then all EC1 disk 1 manifolds would be ready. And continue with disk 3 outlet manifolds A and B.

- Thursday 22nd: finish with disk 3: disk 3 inlet manifolds A and B. Then all EC1 disk 3 manifolds would be ready.

- Monday 26th: if previous days' objectives were not achieved, day to wrap things up (or do more A-B manifolds if they get ready by then). Also, Andrea García starts the pressure tests with disk 1 inlet manifolds.
