NA62 Photon-Veto Working Group Meeting

CERN, 27 May 2009

LAV construction status – M. Moulson (Frascati) –LNF – 4 Dec 2009

Working space for gluing/wrapping

2 vespasiane (1 new - Massimo)2 tables for work/storage1 table for banana assemblyNew shelves

New tool chest and power tools (Massimo)Equipment/furniture basically ready

LAV construction status – M. Moulson (Frascati) –LNF – 4 Dec 2009

Materials for gluing12 4-way gluing rigs (Emilio, Luca)

Glue (ScotchWeld DP490): 5-6 tubes on hand (~60 blocks?)More purchased at CERN, will arrive in Frascati next week

Bonding plates: Enough to complete vessel on hand

Guillotine for manipulating blocks

(Emilio)For safe handling of blocks before addition of mounting brackets

Tvyek patterns and supplies

Pattern:•Emilio has developed pattern for crystal types 11, 14, 15

•Delivered to Genova

•10 test patterns cut at Genova and sent to Frascati

•Should arrive by Monday, 7 December

•If all OK, Emilio → Genova 4 days week of 14 December

•All covers cut (200 pcs) for 1 complete station by holidays

•Need to get samples of crystal types (7, 9, etc.) in next shipment to test pattern

Materials:

•Tyvek 4173D on hand at Genova for ~100 covers

•Emilio will bring 1073D remnants from Frascati for remaining covers

Pre-forming Tyvek (folding/welding)After much discussion, idea is to pre-form Tyvek wrappers using a bad blockWorries about thermal stress on good blocks from welding iron

Table for folding/welding Tyvek around sample block (Sauro)

Mounting hardware for model block, with hinge and handle for lifting (Massimo)

Cleaning and wrapping blocks

Bilancino:Rig to attach to 2 screw holes in flange

Asta:Handle to allow lifting of block from vespasiano(Block can be partly rotated)

Baldacchino:Cradles lifting handle and supports block for cleaning

Design: MassimoFabrication: Massimo, EmilioReady by 14 Dec

Outlook

•Should be ready to glue a batch of blocks week of 14 Dec

•Should be ready to begin serial processing of blocks at beginning of January

•Will need to optimize procedures and working space as we gain experience

•May rethink some hardware as well

Example: Cleaning and wrappingCurrent procedure ergonomic for 2 peopleCan we develop equipment to allow 1 person to lift blocks? (Under study: Emilio)
