<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Thank you all for thinking about our NPS chiller problem. The Hall C techs fixed the leak this morning. It did not leak for the 1/2 hour we observed the pipe. Hopefully, the
fix will hold. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">But just in case it doesn’t. We have one more month to go. So locating a possible spare would be a great piece of mind. </span><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#212121">Another
important parameter to keep the temperature constant is the flow rate. Our NPS chiller has 4,3 gallons per minute. One would need something close (or higher).</span><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt">The NPS experiment in Hall C has a chiller that has developed a leak, do you know if any of the chillers previously used for the SVT are available for them to temporarily use?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt">It has a 3 kW capacity (not sure how much of this is actually needed), only needs to maintain 20C so not a particularly low temperature requirement, and 0.1C stability (also not sure how stringent this is),
which is why I thought maybe one of the older model SVT chillers could be used?<o:p></o:p></span></p>
