I do not have an estimate for the time this will take but it will be significant. I am working on it nights and weekends to make it happen. I don't know if I will make the December review though. This system will have to be tested and inspected which will not be a trivial thing. Please note that the mixed materials in the Swagelok fittings are not in compliance with manufacturer's catalog/manuals and may have to be replaced with brass ferrules and copper tubing.</div><br><div>David Meekins<br>Staff Scientist<br>Thomas Jefferson National Accelerator Facility<br>12000 Jefferson Ave<br>Newport News Va. 23606<br><br>Office: 757-269-5434<br>Cell: 757-968-9076</div><br><hr id="zwchr"><div><b>From: </b>"Marc McMullen" <mcmullen@jlab.org><br><b>To: </b>"David Meekins" <meekins@jlab.org><br><b>Cc: </b>dsg-rich@jlab.org<br><b>Sent: </b>Wednesday, November 16, 2016 2:20:02 PM<br><b>Subject: </b>Re: RICH Pressure calculations<br></div><br><div>Hi Dave, Have you had a chance to communicate with Patrizia on the RICH design authority work? DSG management is trying to prepare scheduling for the near future, so if you have an estimate on the time required. That would provide some valuable information.
