1. Extended Pid in PHENIX (assembly and integration ) 7/28/03 CDR review 07/28/2003, presented by E.Kistenev

2. Retaining PHENIX edge at High P T (1) coverage 4 m 2; (2) cell size 11x22 cm 2; (3) geometry 10 x 16 cells. TOF Aerogel Needs ToF backing to deliver on promises

3. Construction readiness ItemCurrent ReadinessCompletion Aerogel50% availableearly September PMT’savailable Boxes50% availableAugust pc-boardsIn Tsukuba Mech. componentsKnown problems: Side plates, HV protectors, lid extractors, lid holders. Purging systemNeeds strawman design and component ordering (Ruga/Pisani/Mike/Carter) Preamps~available, missing details of the box&mechanics design Cabling (LV/signal)understood and ordered/available Cabling (HV)options known&understood, still looking for chip solution InfrastructureSee P.Kroon’s talk

4. Aerogel Counters -build laminate container; -load aerogel into container; -assemble lid (pc board + lid itself); -install PMT’s, LED, gas connectors and solder all internal leads; -test assembled lid in the black box. - install side bars onto the counter box; - load container container; - install lid; - test assembled counter for light leaks. Repair leaks …..

5. Building Arrays -A-frame -array skeleton;

6. Cabling: trays; preamp boxes; HV&signal cables; Gas connections: -manifold; -distribution lines; System test: -purge; -raise HV; -trigger LED’s; -test for the signals on preamp input/output using scope, check for the light leaks; Live support

8. Racks: Symmetrical configuration North&South; Narrow racks are sufficient to run Aerogel component; LV crate HV crate Aerogel (RICH) FEM & Interconnects LED drivers Wide rack are for the ToF component & Trigger Gas: N2 is the boil-off from the LN2 tank. Heating is due to the long transfer lines (is winter is of concern, do we need to control gas temperature?). Flowmeter (limit ~ few x 100 lph) in the gas house, same for the filter. Integration in PHENIX

9. Goals September 19 th First Aerogel Array ready for Installation. October 1 st North Aerogel Array installed; North Aerogel Rack fully tested and installed (request from JH – FEM to 1008 now); October 10 th North Aerogel Detector is in Big Partition.
