Rates below calculated using Trigger-rate tool run on Enhanced Bias samples of 550k events. (user.SethCaughron.misal1_mc12.EnhancedBias_1031.digit.RDO.v13004004; you can find them in /castor/cern.ch/grid/atlas/atlasgroupdisk/trig-daq/user/SethCaughron). These are derived from the 14 TeV 6.8 million event PYTHIA 6.412 Minimum Bias sample. Enhanced bias is a sub-sample of min bias events that satisfies one or more of the following L1 terms: EM3, MU4, TAU5, J18, FJ18, XE25, TE250.

Trigger rates for 14.4.0 1031 (html).

Note: a few triggers are biased low by enhanced bias cuts. These are XE15, XE20, J5, J10, TE150 (for this sample only these rates have been replaced by rates from full stats min bias run). MBTS* not measured.

10 TeV Luminosity = 1031 14.4.0 full stats

Note this is based on about 150K Enhanced Bias Events from 3M Min Bias sample. No correction was made for high passthrough settings on mu_4tile and mu4_mu6 which have high rates at L2 and EF (this was fixed by hand in 14 TeV rates, and will be fixed with a x20 reduction of passthroughs in 14.5.0.3). Beware of other passthrough rates 2mu6, mu40, which frequently cause confusion. Will try to get a list of these posted soon

A normalization value of 65 mb was used for 10 TeV. {A note on normalization: even though PYTHIA min bias events are used, the cross section comes from PHOJET (historic). The normalization values thus are 70 mb (PHO) instead of 55 mb (PYT) for 14 TeV and 65 mb instead of 52 mb at 10 TeV.} With these statistics the single event sensitivity is 0.22 Hz, so for an unprescaled trigger 0 events corresponds to a rate of <0.5 Hz at 90% C.L. (for an unprescaled trigger the rate upper limit should be scaled down by the prescale).

10 TeV Luminosity = 1031 15.0.0

A normalization value of 65 mb was used for 10 TeV. {A note on normalization: even though PYTHIA min bias events are used, the cross section comes from PHOJET (historic).} With 3M 10 TeV min bias events used to make the enhanced bias samples the single event sensitivity is 0.22 Hz. For version 15, we redid the enhanced bias filtering, the new EB files can be found at: user09.EdwardSarkisyan- Grinbaum.EnhancedBias1500.digit.RDO.e357_s462_d126_0.

10 TeV Luminosity = 1032 15.0.0 Pileup (<4.1> extra MB events at 450 ns)

A normalization value of 65 mb was used as described above. With these statistics the single event sensitivity is 2.6 Hz (I think 500K events would be 13.2 Hz, but 5.1 interactions per crossing).

10 TeV Luminosity = 1031 15.1.0.1 (new Calib)

A normalization value of 65 mb was used for 10 TeV (historic). With 3M 10 TeV min bias events used to make the enhanced bias samples (see V15.0.0 for Enhanced Bias data sample), the single event sensitivity is 0.22 Hz. Note this release temporarily used a new L1 calibration scale resulting in large decreases in jet rates and other triggers.

10 TeV Luminosity = 1031 15.1.0.2 (old Calib)

A normalization value of 65 mb was used for 10 TeV (historic). With 3M 10 TeV min bias events used to make the enhanced bias samples (see V15.0.0 for Enhanced Bias data sample), the single event sensitivity is 0.22 Hz. Note this release returned the L1 calibration scale to the level of V15.0.0 (the L1 calibration scale was temporarily modified in 15.1.0.1 resulting in large decreases in jet rates and other triggers).

900 GeV Luminosity = 1028 15.5.2.1

A normalization of 34 mb is used for 900 GeV, but probably 40 mb would be better (UA5)-this would increase rates by 15% Note: 100k events at 1028 gives .004 Hz single event
