RBX contents for all subsystems
• All components reside in an enclosure/shell which acts as mechanical enclosure and distribution point for services.
• All components are modular – and can be inserted and removed as units.
• RM-19 (HB, HE, and HO subsystems)• RM-73 (HB and HE only)• Calibration Module• CCM (Clock and Control Module)• HV/BV termination• LV termination• Water cooling • Gas manifold for nitrogen inerting of ODU/RM

General Comment about RBX and Components
• The structures are modular. This allows us to gain in the schedule, as assembly, Q/C and testing can be “factorized”.
• RBX enclosures can be built, tested and mounted, independent of components which can be added later.
• RM can be fabricated mechanically. ODU can be fabricated. Electronics and HPDs can be incorporated when available.

Additionals
• Copper fittings and jumper between roof and floor water cooling pipes
• Gas manifold• LV module• CCM• CHUNC• RM pinning• Front protection cover Status of Costing Status of Costing

• Direct extraction using CHUNC
• RM-73, CCM and Calibration Modules• Similar to above, except RM-19s must be removed
first.

Suggestion to allow ODU 73 access
PRR for HCAL RBX 1-March 2001 R.Ruchti 53
Accessibility Issues
• All optical cables for RM-19 visible and accessible in an unobstructed manner for visibility and access to mounting screws.
• Same requested for RM-73, but may not be possible.
• Use of compact extraction tool CHUNC to remove and reinsert modules
• Use of floor tracking to assure proper module insertion at odd angles.
• Mockup studies, Fermilab Lab 5 and Prevessin.
PRR for HCAL RBX 1-March 2001 R.Ruchti 54
HE RBX Issues
• Design: laterally compact, but good access in principle
• Status: enclosure design quite advanced• Integration: careful interaction with Preshower
(SE) and ECAL (EE) services.• Challenge: cooling issues and ODU fiber routing.• Schedule: PPP in June 2001
PRR for HCAL RBX 1-March 2001 R.Ruchti 55
HE RBX Status
• Drawings in progress
• Builds as much as possible upon the design of HB where possible.
• Layout of various internal modules in progress
• ODU in mockup phase

HO RBX Issues
• Design: vertically very compact. Resides within muon absorber which provides for magnetic “focussing” for HPD, and shortened optical cables from HO megatiles.
• Status: enclosure in design, but not advanced• Integration: careful interaction with muon
chamber systems.• Challenge: ODU/HPD cookie placement,
servicing, and optical cable routing to megatiles.• Schedule: PPP in winter 2001
PRR for HCAL RBX 1-March 2001 R.Ruchti 61
HO RBX Status
• Drawings in formative stage
• Awaiting final results from study of magnetic field situation
• Appears that a solution is possible with RBX located at the large z ends of the muon wheels.
