  1. MUON Alignment DAQ (overview) • Often a question is asked: Do we have a single DAQ program or 3 separate DAQ programs for each subsystem? • Our approach to answer above question is: • Keep the DAQ modular for maximum efficiency (Hardware and FE of each subsystems are different. Avoid unnecessarily large overhead.). • Be sure the common issues are addressed and coordinated in order to achieve coherent operation in the CMS experiment.

  2. Outline • Contact people for DAQ in each subsystem • Brief review of each subsystem readout scheme • Common Issues • Schedule and plan

  3. Contact people and brief review of each subsystem readout plan • Barrel: J.Molnar, D.Novak(seeG.Bencze’s talk in the barrel session for more details). • Link: I.Vila(See A.L.Virto’s talk in the link session for more details) • EMU: K. Maeshima(see K.Maeshima’s talk in the EMU session for more details)

  7. EMU Readout Scheme

  8. Common Issues • Synchronization of the data taking • Data exchange among the 3 alignment subsystems. • Common framework for an alignment reconstruction program (COCOA) and Interface - how the muon chamber alignment results being used (data storage, data accessing, issues): • CMS muon chamber geometry and offline muon track reconstruction. (see P.Arce’s talk for more details) • Operation and Monitoring Comment:Use of the CMS DCS system solves much of above issues.

  9. DATA Flow (Conceptual) Geometry of ORCA for the muon reconstruction Barrel chambers positions EMU chambers positions COCOA for the Barrel chambers COCOA for the Link information COCOA for the EMU chambers Readout for the Barrel Alignment devices with DCS interface Readout for the Link Alignment devices with DCS interface Readout for the EMU Alignment devices with DCS interface

  10. DAQ Plan for the Magnet Test 2004 • Should be able to read out the full Link and EMU alignment subsystems and the barrel magnet test setup. • The software must be developed enough that during the magnet test we can have fast feed-back from the data taken. This means: • Interface must be ready such that raw data from DAQ and other necessary data (calibration, etc.) can be readily converted into input format of COCOA. • COCOA should run in a timely manner to give us the fast feed-back on the position/movement of chambers.

  11. Barrel Setup for the Magnet Test 2004 • 10 MAB Board Computers to control the MAB-s • 1 MAB workstation • to communicate with the MAB board computers • to communicate with the chamber part (DCS function) • 5 Board computer hardware configurations with special software • to control the LED-s on the muon chambers (minicrate function)

  12. Summary and Plan • Design of each subsystem DAQ has been worked on and being tested, keeping in mind that there are some common issues (DCS interface, etc.) must be addressed. • Implementation should follow. • milestone: Magnet test 2004 – deliver the operational system in the 1st order. • Continue to implement and deliver the final muon alignment DAQ system for the installation/commissioning of the alignment system and the CMS experiment with good monitoring system and documentation for the long term operation to follow. (see each subsystem report for more detailed schedule)
