Ben, Calum, and Gerardo,
We received the two Gas Delivery systems, and two TMDS units (S1500093 and S1500094).  We assembled the remainder of the table, and then mounted the Gas Delivery system.  Lacking the final mounts, we put the TMDS on a screw jack so we could easily connect it to the Gas Delivery system.  Once all hooked up, we attached the electronics, and put both TMDS systems through their paces, and tested them for ion production.  We had two issues with S1500094 that we fixed.  The first issue was that we accidentally swapped the cables going to the Baratron and Pirani gauges, which we believe damaged the Pirani gauge somehow.  The second was that the cutoff valve leading to the vacuum pump would not seal completely.  Gerardo took the whole thing to the clean room removed the suspect parts and replaced them with new ones sent from Caltech.  Both new parts were found to work fine.  The valve ended up having a cut and frayed Viton o-ring, which explained its problem.  We are going to get an RMA for all things, and see what we can have done.  Currently, the two TMDSs are in perfect working order, and have been fully checked out.  We shipped the TMDS Interface back to caltech for further refinement, and so I can continue testing the units that we have there.
