- Dave: The pressure tests of the gas system started, we found one bad flow controller that Bill is going to send back for repair. Scott connected the CDC and the FDC mixing vessels so that, without one flow controller, we still can supply gas, the same mixture, for both detectors. The fact that CDC and FDC are going to use slightly different gas mixtures is not important in the moment (Curtis).

- Pressure tests were done with industrial gas end of last week. The pure gas will come beginning of next week, then we can start flushing the whole gas system. However, we can start using the gas only after the ODH analyses are signed. ODH-0 in the gas room requires orifices of 0.052" on both Ar and CO2 lines.

- It turned out that we have industrial gas (both Ar and CO2) ordered and used now for the tests of the gas system. An option would be to put filters and continue using it till we get the right gas. Eugene: we should stop using it right away, or when we are done with the pressure tests. Dave prepared documents (attached above) for the flushing of the gas system and the detectors, but it should wait till we get the right gas. We have not decided at this meeting if we need gas filters in addition to what is already in the system, but Bill is looking into different options.
