L1Calo: Installation, Commissioning & Integration

Installation Activities

Integration Tests and Plans

Commissioning

Murrough Landon

20 September 2006

L1Calo: Birmingham, Heidelberg, Mainz, QMUL, RAL, Stockholm

Analogue Infrastructure

Analogue Infrastructure (1)

Cabling

776 short stiff heavy analogue cables to install in USA15

Procedure: preliminary installation, measure length, remove, add connectors (commercial company), test, reinstall

Status: 90% measured, 55% final installation

Estimated completion Nov/Dec 2006

Analogue Infrastructure (2)

TileCal patch panels

All four crates are installed

90% of the required 64 modules are installed (few modules need repair)

Already used in TileCal cosmic trigger for LAr/Tile joint runs

Receiver-PPM patch panels

All six crates have been installed

All 80 modules produced and ready to ship to CERN

Expect to install them in October

Receiver system (Pittsburgh)

Fully installed for several months

Digital Cables

Preprocessor to CP/JEP systems

1888 thin, flexible, fixed length, pretested cables

All 8 PP crates are connected to all 6 CP/JEP crates

So want all crates installed before doing this cabling

Expected schedule November 2006 to January 2007

Fibres to L1Calo RODs

~300 fibres to be installed, late 2006

L1Calo to CTP

Preliminary installation for integration test

Some problems observed (not seen in basic cable tests)

Cables (7) need to be removed, fixed and reinstalled

L1Calo to ROS/RoIB

Installation of all fibres early October 2006

Integration Tests (1)

Calorimeter Cable Tests

Subset of trigger cables from calorimeters (mainly TileCal) checked using two prototype preprocessors and VME readout (no RODs)

Results presented at last TDAQ week

LAr cables also tested thoroughly by Pittsburgh

Since then focus on ROD readout of preprocessors

Will repeat this calorimeter integration and cable test exercise with ROD readout and full crate of final preprocessors as these become available – aiming for late October 2006

Test bed for development of calibration procedures

Lot of work still to do: online/offline SW, databases...

Integration Tests (2)

L1Calo (CMM) to CTP

Successful integration test of one final merger module (CMM) to CTP input was made in July

Some problems with faulty cables identified

Minor CMM firmware bug in treatment of parity

Successful connection from CTP output to LTP

Integration Tests (3)

L1Calo ROD to ROS

Tests of a prototype 9U ROD in USA15 environment with inputs from preprocessor and cluster processor modules and output to “mobile” ROS with FILARs

Expect integration test of this prototype ROD with final ROS (ROBins) in October – once ROL fibres laid

Later, test integration with LAr/Tile/DAQ partition...

Integration Tests (4)

L1Calo ROD to RoIB

First integration test of our prototype 9U ROD to final RoIB in October 2006 (after ROLs laid)

Installation of the Full Trigger (1)

Cluster & Jet/Energy Processors

Modules now in production

Expect full installation & commissioning from end of 2006

Final connection to CTP on similar timescale

Preprocessor

One crate of preproduction PPMs expected to be installed at CERN in October

First modules from full production expected Jan 2007

RODs

One prototype now in USA15 for integration tests

First modules from full production expected Jan 2007

Installation of the Full Trigger (2)

DCS

Need operational DCS before running full crates in USA15

Custom monitoring of L1Calo crates developed

Monitors both crates and modules

Lot of work so far, but all outside CERN

DCS PC for LVL1 now installed in USA15 (by DCS group)

Still to be commissioned, cabled and used by L1Calo

Now needs to be a priority

Summary

Progress

Analogue infrastructure installation proceeding well

Some integration tests in USA15 completed successfully

Schedule

Digital infrastructure (crates, cables) coming soon

Installation of algorithmic parts (Cluster, Jet/Energy triggers) starting last quarter of 2006

Preprocessor and readout in first quarter of 2007
