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)

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

Dummy strip modules

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.

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.
