DAQ & ECS for TPC commissioning

This document outlines the efforts made and upcoming tasks related to the Data Acquisition (DAQ) and Event Control System (ECS) for the Time Projection Chamber (TPC) commissioning. We have made significant strides in equipment setup, transitioning between sectors, and coordinating with high-level trigger (HLT) systems. Key components such as the LTU proxy and HLT proxy are discussed, along with configurations, event control, and the importance of collaboration for successful test runs and data acquisition. Future plans include installing DATE V5.19 and enhancing interactions with real DCS and HLT proxies.

  3. Changing from one sector to another • Equipment Ids must be changed • Equipment Ids == data origin (i.e. from which sector) • Table of equipment Ids agreed (TPC, Offline, DAQ, HLT) DAQ, ECS for TPC commissioning

  4. Working with HLT mode A+ • A+ • Data sent to HLT farm (splitters on and ‘forced’) • DAQ does not receive data from HLT (no HLT LDCs) DAQ, ECS for TPC commissioning

  5. LTU-proxy • A component of the ECS/TRIGGER interface • A process running on the VME crate where the TPC trigger partition (LTU, TTCvi, TTCex) is located (lnxpool13) • Is configurable • Two run modes (BC and pulser/edge) • In BC mode allows the selection of the event frequency • SOD and EOD events can be enabled/disabled • Not a debugging tool • Does not offer all the feature of the ‘vmecrate ltu’ interactive program (A.Jusko) • Gives to the ECS the control of the LTU • Connected to the DAQ network (ethernet over fiber) • Under the ECS control, it allows the generation of sequences of events starting with a SOD event and ending with an EOD event DAQ, ECS for TPC commissioning

  6. HLT-proxy • A component of the ECS/HLT interface • Will run on the HLT farm • For the time being we can use for test purposes a dummy version or (better) the HLT-proxy with TaskManager emulation provided by S.Bablok • The HLT-proxy with TaskManager emulation runs on the same machine as the Detector Control Agent DAQ, ECS for TPC commissioning

  7. ECS: TPC Detector Control Agent • Controls standalone runs • Starts / stops DAQ and Trigger (LTU) • Dummy DCS for the time being • Detector always ready • Dummy HLT-proxy or HLT-pxoxy with taskManager emulator provided by S.Bablok • Receive the right sequence of commands • It is a good starting point for the required development DAQ, ECS for TPC commissioning

  8. DCA: before starting a standalone run DAQ, ECS for TPC commissioning

  9. Output messages from HLT-proxy DAQ, ECS for TPC commissioning

  10. DCA: after a standalone run DAQ, ECS for TPC commissioning

  11. To do • DAQ: • Installation of DATE V5.19 (Monday 10 July 2006) • Main difference TDSM (migration of files to CASTOR) • Probably the last version supported on SLC3 • ECS: • Interaction with a real DCS • Interaction with a real HLT-proxy • Implementation of various types of runs • Pedestal runs (in progress) • Implemented in ECS • Roland preparing the required scripts • To be tested this week • Datapath Test runs • Calibration Pulser runs • Physics runs • Require a close collaboration with Luciano, Uli, Roland, ….

  12. Pedestal runs: ready for testing DAQ, ECS for TPC commissioning
