EMU Slice Test Run Plan a working document

Executive Summary / Status • CSC position – at YE-2 – On-chamber electronics available • Life support is available – HV+LV: TB equipment – gas: T-ed of the test-B supply • Off-chamber electronics – enough VME modules for 3 chambers in two crates • TMB, DMB, CCB and MPC – VME backplanes are shipped from UF – dynatem orders are placed • trigger & clock distribution – TTCvi, TTCvx/ex and 6 U rack • unavailable – VME controller • temporary replacement • TF electronics available – SP, CCB, back plane – 9 U rack + VME controller • controllers are ordered • control & daq PC is available – to be equipped with SBS controllers for TF and TTC crates Details on the following pages

choice of CSC location • station: YE-2 – 100% completed – YE+ stations will be lowered first • more time for testing • close to DAQ room – not relevant at this moment, but expected to be of importance for the CMS Slice. Test • close to DCS test stand – allow near future integration • towards USCMS Slice Tests – both DAQ and HCAL preferences are relevant • HCAL’s preference not clear – the success of EMU Slice Test would be that this is not an issue: provided we have “CSC life support” any set of chambers should be configurable on a (very) short time scale.

CSC Life Support • HV – test beam CAEN PS will be hooked up • possibly adding a win-xp control PC • LV – test beam LV supplies can be used • 4 pairs available • gas – T-ed of the gas supply for test B

On-chamber electronics • all chambers on station -2 are fully installed • what chambers have skewclear cables routed – target chambers should be ready • accessibility – unable to get at CFEB for back chambers – unable to get the LV boards • cover plates can not be removed – ALCT can be reached • provided the disks are not closely packed

Off-chamber electronics • Peripheral Crate (PC) – mini-rack is installed • hosts max. 2 PCs – space for std. VME crate (Electronics Pool) • max. 1 per mini-rack

Peripheral Crate • Back plane – use std. VME crate for old and previous production prototype • cooling: fans • sticks out ~10 -20 cm – no an issue – use new crate for new prod. -type backplane • this involves a non-standard or new power supply – new PS will not be available soon • cooling: hook up to water manifold • new production type backplane will not be available soon – use new crate with temporary fix for the PS • cooling: separate tray of fans

Electronics • VME controller – Dynatem D 360 • should come with the back plane • lack of dynatems – two new D 360 s are ordered – New prototype (OSU) • different ethernet connections – optical Gb • impact on software – HAL support?

Electronics (cont’d) • TMB – 4 TMB 2004 at CERN • DMB – 3 DMBs at CERN • CCB – CCB’ 01: one TF-prepared version at CERN – CCB’ 04: 2 at CERN • MPC: – 1 at CERN

Trigger & Clock Distribution • TTCvi + TTCvx(ex) – requires dedicated 6 U crate – use the new CERN/CMS standard: CAEN VME controller • two controllers will be ordered – availability? • none found so far • NIM rack – modules: • scintillator trigger – discriminators, coincidence units, fan-out, HV supplies • TF trigger – ECL translator – all available from Test. Beam equipment • CERN E-pool • Fibers – enough for initial TTCvx set-up • Alternative Solution – run without TTC branch and rely on CCB clock only – allows us to start e. g. timing and calibration procedures

DAQ Electronics • DDU/DCC – initially using the old DDU • hosted in the Peripheral. Crate, no need for a special crate + controller – when available use the Emu. FED crate • DDU/DCC/backplane/controller • minor software effort • old/new DDU can take up to 15 inputs – some defect channels are documented • DAQ pc has Gbit ethernet card and software – previously used at Test. Beam

TF electronics • MPC – in the Peripheral. Crate – only one module at CERN • need more when adding crates – not urgent • TF backplane and SP – currently on loan to the Vienna group • should be available by the end of November’ 04 – crate + VME controller • crate unavailable (E-Pool) • VME controller will be ordered (CAEN) – specially prepared CCB at CERN (currently on loan to Vienna group) • MS – no real need for MS

Additional Requirements • The system should be using SP triggers as soon as possible • However, to bootstrap the system a scintillator based trigger may proof to be useful • Requirements – NIM logic and NIM HV supplies – scintillators + mounting structure
