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
SM crate load test @ CERN • Design • blueprints • materials • safety • Realization • The SM-crate proto has been tested at 0° angle
SM crate load test @ CERN Dummy strip modules
Catania planning for 2007-8 (mechanical) 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 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.

Barrelto EMCAL trackmatching Presented to ACAT07 First version of track-matching ready and in CVS. Track matching efficiency and contamination for PHYTHIA minimum bias events Aim: To clean the cluster sample for photon analysis (jets) adding PID information from EMCAL to high momentum charged tracks Alice-jet1 Catania
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.
