The diagram shows 24U of rack space allocated per rack. This location would assure that cable lengths can be kept minimal for both RICH detectors. I have included photos of the locations. I think if the HV crates for FTOF are lowered 5-6 inches (see rack bottom photos for C3-4 and 5) and the cable management (at the top) is removed there should be enough space.<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Thanks,<br data-mce-bogus="1"></div><div><br></div><div data-marker="__SIG_PRE__">Marc McMullen<br>Physics Division<br>Detector Support Group<br>7738</div><br><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><b>From: </b>"Eugene Pasyuk" <pasyuk@jlab.org><br><b>To: </b>"Matteo Turisini" <matteo.turisini@gmail.com><br><b>Cc: </b>"rossi patrizia" <rossi@jlab.org>, "clas12 rich" <clas12_rich@jlab.org>, "Serguei Boiarinov" <boiarino@jlab.org><br><b>Sent: </b>Thursday, July 21, 2016 10:39:18 AM<br><b>Subject: </b>Re: [Clas12_rich] RICH electronics<br></div><br><div data-marker="__QUOTED_TEXT__">Matteo,<br><br>You added junction boxes.
