FDC Update
CDC Update
- Construction: Curtis reported on construction status. Row 17 is in progress and we have enough straws to complete row 20. According to Tim's earlier communication, the new straws from Lamina should be ready in about 6 weeks.
- Hook-up wires: the silver beads and conductive rubber have been ordered. Slava will send CMU some lifesize drawings of the endplates showing the HVBs so that the connection pattern can be determined.
- Solder: Fernando suggested that we use Kester 285. This leaves flux residues which are non-corrosive and non-conductive (and fungus-resistant). We propose to use this; we will not need to clean off any flux residue.
- Prototype: Naomi is making an outer plenum for the prototype to counteract its leaks, it is nearly finished.
- Gas flow: Beni calculated that the CDC would require approx 3L gas/minute, so one pair of cylinders would last around 3 days.
