This should isolate the airflow more from the compressor's on-off cycle.<br><br>The second test is to see the maximum airflow capable from one outlet of the air cooling panel. This would tell us more about the cooling capabilities we have for the existing system and whether we could potentially run the current system for two RICH sectors.</div><div><br data-mce-bogus="1"></div><div>We will send the results of these tests when they are complete.<br></div><div><br data-mce-bogus="1"></div><div>Best regards,<br data-mce-bogus="1"></div><div>Tyler<br data-mce-bogus="1"></div><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><b>From: </b>"Mirazita Marco" <Marco.Mirazita@lnf.infn.it><br><b>To: </b>"dsg-rich" <dsg-rich@jlab.org><br><b>Sent: </b>Monday, May 7, 2018 3:42:56 PM<br><b>Subject: </b>[Dsg-rich] RICH status<br></div><div><br></div><div data-marker="__QUOTED_TEXT__">Hi all,<br>I made today a new set of calibration runs, see <br>https://logbooks.jlab.org/entry/3573975.<br>The HV and LV are off.<br>The compressor can now be turned off.<br>Marco<br><br>_______________________________________________<br>Dsg-rich mailing list<br>Dsg-rich@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/dsg-rich<br></div></div></body></html>
