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.

PRR for HCAL RBX 1-March 2001 R.Ruchti 33

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

panels• RM-19 (QIE) and RM-73• Retrofit of holes in RBX flooring for mounts

HB RBX Production Status

• HB PPP-1– At CERN in mockup at Prevessin Site.

• HB PPP-2– At Fermilab for electrical integration and 186 testing

• HB PPP-3– At Notre Dame for thermal tests and 186 testing

• HB PPP-4– Under fabrication at an outside vendor and assembled at

Mississippi. Production drawing test bed.• HB RBX production begins April 2001

PRR for HCAL RBX 1-March 2001 R.Ruchti 35

HB access/serviceability issues

• RM-19• Removal of optical cable protective covers• Removal of optical cables, calibration cables• Removal of any blocking services/cables• Direct extraction using CHUNC

• RM-73, CCM and Calibration Modules• Similar to above, except RM-19s must be removed

first.• Removal of any blocking services/cables.• Extraction using CHUNC

PRR for HCAL RBX 1-March 2001 R.Ruchti 36

HB access/serviceability issues

• HV/VB termination and LV termination• Removal of RM-19• Extraction using CHUNC• Service in situ

• HV/VB backplane, electrical backplane• Removal of all RM, CCM and Calib Module• Removal of HV/BV and LV terminations• Full extraction

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.
