12 Oct 2021: Following the JIRA https://its.cern.ch/jira/browse/CMSHLT-2164 new streams were defined:

  • ALCALUMIPIXELS replaced by ALCALumiPixelsCountsPrompt
  • ALCALUMIPIXELSEXPRESS replaced by ALCALumiPixelsCountsExpress

Definition of the Express Dataset

Regular Express

Path Rate
HLT_ZeroBias 20 Hz
HLT_Random 10 Hz
HLT_Physics 10 Hz
HLT_ZeroBias_FirstCollisionAfterAbortGap 10 Hz

HLT_ZeroBias_IsolatedBunches and HLT_ZeroBias_Alignment can be dropped for the beam test.
HLT_IsoMu27(24,20) / HLT_Mu17_TrkIsoVVL_Mu8_TrkIsoVVL_DZ / HLT_Ele23_Ele12_CaloIdL_TrackIdL_IsoVL can be dropped for the beam test.
More on JIRA https://its.cern.ch/jira/browse/CMSHLT-2173.

Express Alignment

Path Rate
HLT_HT300_Beamspot 60 Hz
HLT_ZeroBias_Beamspot 60 Hz

HLT_HT450_Beamspot not needed for test beam.
HLT_ZeroBias_Beamspot rate increased from 20 to 60 Hz if PU=0.1 in order to have O(10^2) PVs/LS (see BeamSpot at AlCaDB workshop 2021).
More on JIRA https://its.cern.ch/jira/browse/CMSHLT-2174.

Notice - the rate and paths of Beamspot may depend on the run conditions. For instance, for low pileup / VdM conditions, we could have a lower HT path (usually HT60) and a higher rate of HLT_ZeroBias_Beamspot (up to 60 Hz if the PU is around 0.1, up to 500 Hz if the PU is around 0.01). These are just guidelines - always contact the Beamspot experts!

Tracker Calibration

  • For detector ageing studies: To be able to monitor this with needed accuracy we’re going to need:
    • 100--150Hz of "SingleX" (X=muon,electron) events for the small bias scans
    • 500Hz of "ZeroBias"-like events for the full scans (SiStripCalMinBias)

HCAL

  • HF and HO will be essentially unchanged from 2017 to 2018
  • For HE, the photodetectors and front-end electronics are upgraded:
    • HPD -> SiPM, up-to-3 depths -> up-to-7 depths
  • For HB & HE, reco algorithm will be upgraded from M2 to MAHI for offline
    • For HLT, transition to MAHI with full depth is still needed to be discussed
