## EMU M&O Phase

**Goals**
- Commission CSCs, FEE & Peripheral Electronics
- Slice Test: from “Cosmic ” to  “Mass Storage”
- Cosmic  track Trigger Primitives  DAQ Chain  Physics Object
- Slice Test will be performed on a 200 f sector of the EMU Detector
- Slice Test Operation
- i.e. from *“Part of the Detector working some of the time”* to 		 	    *“All Detector working all the time”*
- Operation Readiness will be achieved on 100% of the EMU Detector
**“****Two Prongs” Approach**
- “Prong #1”: Test and Commission CSCs, FEE, etc. as soon as conveniently possible after they are installed in SX5  at CERN
- “Prong #2”: Develop Slice Test and Trigger DAQ on Cosmic Stand in US (UF) to import lately to CERN.
- Convergence at “Slice Test” time at CERN (~2004-2005)

## EMU M&O Phase Commissioning

**“****Prong #1” – Commissioning work on 100% EMU. All CERN-based.**
- Test “Mechanical Properties” of the EMU System
- Test CSCs for broken wires, gas leaks, HV performance
- Test and cross-check water and gas delivery systems
*Status: well advanced, under execution*
- Test FEE & Peripheral Crates properties of the EMU System
- Check dead channels and performance, start calibration work
- Methodology evolving from “Stand-alone FAST Site DAQ” (now) to CMS-based xDAQ system (later) including DCS and Calibration schemes.
*Status: initial phase planned, tooling in place, ready to start (Nov. ‘03)*
- Perform “Long Term LV Test” of Electronic System
- CSCs have been tested for “long term HV” at FAST sites (3 months under operating HV conditions).
- FEE has been powered only for ~ one week during FAST site testing, insufficiently to really explore the full “infant mortality” curve.  Start “Long Term LV Test” with goal of powering FEE for ~3-5 months for all installed CSCs to detect problems as early as possible.
*Status: planning stage, expected to start in Spring ’04.*

## Commissioning - Mechanical Properties TestWork In Progress

**Piping Check #1**

**Piping Check #2**

**Check on Gas **
**Rack**

**Check for CSC**
**Broken Wires**

## Commissioning - FFE Properties TestWork Ready to Start

**Portable DAQ System for US FAST Sites**
- Portable VME in 4 different positions with ~5m extension skew-clear cables.
- PC on SX5 floor, connected by Optical and Cat5 network links.
- Portable LV available. Start with FEE testing only since no HV or gas available from CMS infrastructure.
- Perform subset of “FAST Sites” tests to determine dead channels and/or disconnected cables.

**Commissioning - FFE Properties Test****Work Ready to Start**

## Slice Test and Trigger DAQ Development

**“****Prong #2” – Slice Test on EMU. UF-US based (FY04) and the CERN-based (from Summer ’04 Test Beam/Slice Test onward).**
- Use U.Florida Cosmic Stand as Test Bench for Peripheral Crate and FED Crate tests.
- Test DDU/DMB/TMB/etc.
- Interface with TrackFinder system.
*Status: critical mass of programmer in place, under execution. One-week workshop in UF on Jan. ‘04*
- Transfer and test system on Summer ’04 time-structured Beam Test.
-  Normal evolution of previous step, sligthly different crate configuration due to Test Beam constraints.
*Status: under planning*
- Slice Test in SX5.
*Status: under planning*

## Slice Test and Trigger DAQ DevelopmentSlice Test Planning

**Slice Test**
- Start with a 200 sector of ME2/2 Chambers
- 2 ME234/2 CSCs mounted on YE+2
- 1 CSC belongs to the “lower layer” CSCs.
- The second CSC can be temporarily installed, if necessary, even if the ME2/1 chambers are not installed yet.
- Temporary “Peripheral crates” can be installed if necessary. Peripheral Electronics (DMBs, TMBs) from production.
- FED Crate sitting at the foot of the disk
- Subset of “Slice Test” checks will be performed on 100% of the EMU system after production crates and boards are installed in Commissioning Effort.
