That is with the exception of the RICH gas controls interface chassis. <br> <br> This is a chassis which is being assembled by the DSG, it contains two power supplies (24VDC and +/- 15V) which are used to provide power for the mass flow transducers, humidity and temperature sensors. It also provides an interconnect for the sensors and transducers to the RICH Interlocks cRIO. The chassis has circuit protection fuses, is grounded, and the power supplies are completely enclosed to eliminate any electrical shock hazards.<br><blockquote cite="mid:2029587903.2234436.1478024622629.JavaMail.zimbra@jlab.org"><div style="font-family: arial,helvetica,sans-serif;

Once defined, DSG will provide documentation and training to the Hall B staff responsible for daily operation of the detector and any after hours on-call support. Once on, the gas operation will not be controlled by any instrumentation such as a mass flow controller, the system is set up to always flow gas/air as long as everything is in working order.<br><blockquote cite="mid:2029587903.2234436.1478024622629.JavaMail.zimbra@jlab.org"><div style="font-family: arial,helvetica,sans-serif;

The piping and valve equipment is all standard, we do not perceive any necessary adjustments to valves once they are set. The tank is above the 15PSI limit and is considered a pressure system, but there are engineer specified relief valves in the design and there are no welds. Saptarshi can probably give you more specifics, if you need them.<br><blockquote cite="mid:2029587903.2234436.1478024622629.JavaMail.zimbra@jlab.org"><div style="font-family: arial,helvetica,sans-serif;
