> > Initial discussions of proposals to provide open CARME chamber and provide access to near and far detector chambers > > We assume that we need to complete all work installing and testing DSSSDs and re-assembling CARME by Feb 2022 in readiness for bakeout. > > > > > Proposal #1 > > Disconnect far detector chamber section from mid-chamber section > Disconnect DN350CF flange from near detector chamber > > Crane to support near detector chamber and mid-chamber sections > > Remove feet of near detector chamber and mid-chamber sections > > Install cradle(s) beneath near detector chamber and mid-chamber sections > > Use for fork lift to remove cradle(s) + near detector chamber and mid-chamber sections - ML confirms that an appropriate fork lift is available > > > Proposal #2 (suggested by ML) > > Design and fabricate table plus rails to extend transverse rails of CARME chamber support assembly > The CARME chamber support assembly comprises the 'feet' plus two-stage welded Al frame > > Disconnect far detector chamber section from downstream section > Disconnect DN350CF flange from near detector chamber > > Slide CARME chamber plus upper stage of Al support frame transversely onto table > > Use crane to move CARME chamber to work area > > > Other discussions > > Discussed workarounds to enable install of FEE64s (outside ring, upper feedthrough) which currently conflicts with longitudinal beam of gas jet target support frame. > > > To Do > > Edinburgh > > - investigate feasibility of proposal #2 > - investigate how much space is required to install FEE64s (outside ring, upper feedthrough) > e.g. by extension of transverse beams of gas jet target support frame, move current assembly outwards from ring c. 20-25cm > > > GSI > > - investigate feasibility of gas jet target support frame changes outlined above e.g. movement of gas/water services, purchase of longer cross beams etc. > > > Suggest meeting (online) to discuss results of these investigations and continue discussions w/c August 22 Encoding: HTML ELCode plain Suppress Email notification
