WLS fibers processing

Lead procurement (proto)

CT- Catania

APD characterization and test

SM Crates production


Lnf status

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)

  • 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.

(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


Emcal project update italy

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

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.
