EMCAL: project update- Italy -
LNF - Frascati• Fixture production
• Module assembly (proto)• WLS fibers processing
• Lead procurement (proto)
CT- Catania• APD characterization and test
• SM Crates production
Federico Ronchetti INFN, Laboratori Nazionali di Frascati
LNF status• Module production
– design fixed recently (25-26 june)• Universal fixture production
– Completed: Base, tool-plates, sleds, cylindrical rails– Ongoing: center-blocks, load cell plates, cross-beam
• Vacuum chamber for WLS fibers processing– Magnetron gun finally delivered and installed– Chamber closed– Out gassing chamber (10-8 bar)
• WLS fiber polishing – First bundles ice-polished– Quality checks underway
• Lead procurement– Lead tiles for prototype delivered– Ongoing reshuffling (from by-measure to by-module packs)

Fixture parts
Fixtures realization progress
Picture not up-2-date: more components than shown have been machined
U. Fixture• All components
materials for missing parts are at hand
• Design for proto is module finalized (WSU EMCAL meeting last 25-26 of June)
• Full fixture production (2xLNF) over by the end of July.

CT work in progress
• Undergoing activity in CT:– EMCAL Super-Module Crate Prototype– Installation of universal module stacking
fixture (delivered by LNF)
• Activity in CERN– Mechanical Integration of SM-crate– Load Tests
The crate prototype
• Design– blueprints– materials– safety
• Realization– The SM-
crate proto has been tested at 0° angle

Additional testing phases
Mechanical work summary for 2007
Work in progress @ CT:– Installation of 1 universal stacking fixture and 1
compression table.– Procurement of ancillary equipment (load cells,
amplifiers, etc)
Work in progress @ CERN:– Load Test of the SM crate proto at 90°– Insertion test SM– Construction of the insertion plane
Catania planning for 2007-8

Catania activity electronics, offline New lab space available for massive APD tests
Procured all the cards of the standard PHOS/EMCal electronic chain to be used for the APD test. This standard CERN set-up is almost ready (work is in progress on the software installation).
Draft for protocol for APD test established
First prototype for APD characterization as a function of the temperature is ready. Characterization of ALL 85 APD+CSP is done.
First version of track-matching ready and in CVS.

Presented to ACAT07
Aim: To clean the cluster sample for photon analysis (jets)adding PID information from EMCAL to high momentum charged tracks
Catania planning for 2008
(electronics, offline)
• APD procurement
• Test setup optimization
• start of massive APD testing
• Test beam data and cosmic ray data analysis
• Track-matching optimization and simulation studies on jet and electron showers.
