CDC Update

1. Status of the construction

Row 19 is complete. Tim reported that the outer shells have arrived at JLab, have been cleaned and deburred and will be shipped to CMU in the next few days.

1. Status of the straws

We have run out of straws. Patrick had emailed that he has the new material and estimated that all being well, he should have the straws ready for shipping soon after May 8.

1. Hook-up wires

Upon returning to the supplier for the terminators the price had risen dramatically and so we are reverting to an earlier design for the hook-up wires, using a lugged ferrule. Curtis will sent Tim drawings. It might be possible to shrink the PCB slightly and splaying out the connection points would make it easier to work with. About 20% of the hookup wires have been made - for one end of each wire we require the O-ring and bushing. Tim said the ferrules were ordered around 3 weeks ago.

1. Preamp

The modified preamp sent by Fernando matches the range of the fADC, we have let Fernando know that this is fine. Gerard just has some tests to run with it.
