Even if the design authority, Dave Kashy, approves the system tomorrow (12/16/16) and we order the equipment (gas, valves, etc.) right away and the equipment arrives mid-January, 2015, it is crystal clear that we will be unable to put the system together for the KPP, a week before Feb. 3, 2017. At best, if everything goes well can expect the system to be ready by 3/1/17. Details will be provided by George, who has developed a comprehensive day by day work schedule. In addition to the DC gas system, there is much work to be done on the SVT.</p><p style="margin: 0px;" data-mce-style="margin: 0px;"> The alternative is to use the wire chamber test stand gas system for the KPP. This approach will work, provided we have the gases in place by mid-January 2017. Again, details will be provided by George.</p><p style="margin: 0px;" data-mce-style="margin: 0px;"> George and I have identified two people: Denny Insley and Morgan Cooke for primary and immediate training on the gas system - as we start turning the system on. Other staff members of the Hall B Engineering group, who are expected to be on call, could be trained by them.<br></p><p style="margin: 0px;" data-mce-style="margin: 0px;">Amrit</p></div><div><br></div><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><b>From: </b>"burkert" <burkert@jlab.org><br><b>To: </b>"Amrit Yegneswaran" <yeg@jlab.org>, "dsg-dc" <dsg-dc@jlab.org>, "David Kashy" <kashy@jlab.org>, "Mac Mestayer" <mestayer@jlab.org>, "Glenn Young" <gyoung@jlab.org>, "dsg-internal" <dsg-internal@jlab.org><br><b>Cc: </b>"Patrizia Rossi" <rossi@jlab.org><br><b>Sent: </b>Wednesday, December 14, 2016 11:07:45 AM<br><b>Subject: </b>Re: DCGAS line installation in Hall B (Critical Path Items)<br></div><div><br></div><div data-marker="__QUOTED_TEXT__"><div class="moz-cite-prefix">Amrit, the KPP run officially starts on February 3.
