Development and Commissioning of Single-beam Chains for HLT: Progress Overview

This document outlines the phased development and commissioning of single-beam chains within the HLT framework using SingleBeam_v1.py and SingleBeam_v2.py scripts. The first phase focuses on MBTS commissioning with 32 L1 items, achieving more or less complete HLT taus. The second phase aims to incorporate L2 and EF algorithms with minimal alterations, avoiding C++ changes. Notable chains involve MBTS_A and MBTS_C, emphasizing loose tunings and integration of essential tracking features. Progress updates and testing necessary for efficient online deployment are also discussed.

  1. Single-beam chains

  2. Single-beam chains • Being setup in TriggerMenuPython (Rasmus): • In SingleBeam_v1.py and SingleBeam_v2.py • First phase (SingleBeam_v1.py): • MBTS commissioning with 32 L1 items + MBTS_A/MBTS_C • HLT: taus more or less complete; rest incomplete • Second phase (SingleBeam_v2.py): • Only L1 so far • Would like to have L2 and EF algorithms with minimal changes: • No c++ changes if possible • Loose tunings (parameters) of FEX and hypos • So far: • Loose chains planned from each slice (slice contributions later) • Chains starting from MBTS/something else: • T2CaloEgamma: • Start from MBTS_A or MBTS_C and open wide ROIs • Add a Hypo algo after T2Calo with very loose cuts • TrigEgammaRec: • EF AllTeAlgo to do unseeded full-calorimeter reconstruction (Phillip) • Currently no tracking for either L2 or EF: to be added Core & Slices Coordination - 1/9/08

  3. Core & Slices Coordination - 1/9/08

  4. T2CaloEgamma from MBTS • Tested online (Denis and Alex) • NAV_ERROR returned by algo when no TrigEMClusters produced • All events sent to debug stream • Needs minor fix to algo (would always be necessary) • Taken out of the menu; Alex working to re-integrate it • Points to necessity of testing new chains online asap Core & Slices Coordination - 1/9/08

  5. L2 muon full scan • Plan to use a chain modified from mu4_dimu_fs • Starts from L1_MU4 • HLT chain counter 390 • L2_MU4_DiMu_FS • EF_MU4_DiMu_FS • Uses TrigDiMuonFast at L2 • Plan to use existing L2 setup in new chain • A muon trigger from the endcap is possible (see talk by Masaya) in the last Core & Slices meeting http://indico.cern.ch/conferenceDisplay.py?confId=24854 Core & Slices Coordination - 1/9/08

  6. Plans • This week expect to have T2Calo running from MBTS • Add tracking (full scan) • Add full-scan muon chain from L1 endcap item • Anything else? Core & Slices Coordination - 1/9/08
