L1 Operation and Characteristics • “And-or” terms provided by L1CTT/CPS, L1FPS, L1CAL, L1Muon, L1FPD, Luminosity Monitor, and the Accelerator are fed to the L1 FRAMEWORK. Extremely flexible definition of terms. • There are 256 “and-or” terms. • These terms can be “and-ed” and “or-ed” to create L1 SPECIFIC TRIGGERS. This permits the correlation of detectors at L1 and very sophisticated triggers! (Run I permitted only “and-ing” of terms) • There are 128 L1 specific triggers. • If L1FW detects a trigger then L1 trigger information and some FE data are sent to the L2 preprocessors.
L1CTT/CPSL1FPS • L1CTT/CPSPrinciples of Operation • Feed all axial fibers into gate arrays. Trigger if a fiber combination is consistent with pT > 1.5 GeV in 4 PT bins. • Tag the trigger if a coincident CPS element is above threshold. Terms for CPS with no trk (g), jets, t • Collect results from 80 front ends for transfer to (1) L1 Framework (2) L1 Muon and (3) L2pp’s. • L1FPSPrinciples of Operation • Tag U/V strips above threshold before/after Pb. • Match tracks before Pb with deposition after Pb. • Collect Results from 32 front ends for transfer to (1) L1 Framework (2) L2pp.

L1 Muon • Alphabet soup: • MTM=Muon Trigger Manager (also used for L1CTT/CPS,L1FPS,L1FPD) • MTCM=Muon Trigger Crate Manager • MTC05 Muon Trigger Card 05 • MTC10 Muon Trigger Card 10 • MCEN Muon Centroid • MCCM Muon Centroid Crate Manager MTCXX
L2 Operation and Characteristics • The L2pp’s reformat and refine the data and transmit found objects to L2Global. (L2STT will give impact parameter and refined track pT late 2001.) • L1Global performs refined tests of objects and does kinematic and spatial correlations. • If L2Global detects a trigger it informs L2 and FRAMEWORK for readout of the data to L3. • At the start of Run II there will be 128 L2 triggers matched one-to-one with the L1 triggers. Expansion beyond 128 will be implemented when required to avoid a physics limitation.

L3 Filtering Principles Primitive Tools -- Physics Tools -- Filters • Primitive tools unpack and find primitive objects • vertices, primary and displaced • tracks • clusters in calorimeter, preshower, tracking • segments in A or B/C layers • muon tracking in calorimeter • Physics tools then find physics objects. These can be specified. These mirror L2 but are improved by access to all data. • jets, electrons and photons, muons, taus • missing Et, scalar Et... • Filters select objects. • Relational filters operate on selected objects. For example invariant and transverse mass, Ht, separation
