Abstract

For the 1994 Tevatron collider run, CDF has upgraded the electron and photo trigger hardware to make use of shower position and size information from the central shower maximum detector. For electrons, the upgrade has resulted in a 50% reduction in backgrounds while retaining approximately 90% of the signal. The new trigger also eliminates the background to photon triggers from single-phototube spikes.

Digital electronics for the inclusion of shower max and preshower wire data in the CDF second-level trigger

Conference Dawson, J; Byrum, K; Haberichter, W; ...

As part of the upgrade program at CDF, electronics has been built to bring the shower max (CES) and preshower (CPR) data into the trigger at level 2. After each crossing, 384 bits from shower max and 192 from the preshower wires are latched. Data from tracks are bussed to this module to provide the wire address and momentum which are then successively compared to the wire data in large look-up tables. Approximately 50 nanoseconds is required to determine a match, write the results in FIFO, and make the results available to track memory. Monte Carlo analysis has indicated thatmore »« less

Level-3 Calorimetric Resolution available for the Level-1 and Level-2 CDF Triggers

Conference Canepa, Anadi; Casarsa, M; Cavaliere, V; ... - eConf C080625:0040,2008

As the Tevatron luminosity increases sophisticated selections are required to be efficient in selecting rare events among a very huge background. To cope with this problem, CDF has pushed the offline calorimeter algorithm reconstruction resolution up to Level 2 and, when possible, even up to Level 1, increasing efficiency and, at the same time, keeping under control the rates. The CDF Run II Level 2 calorimeter trigger is implemented in hardware and is based on a simple algorithm that was used in Run I. This system has worked well for Run II at low luminosity. As the Tevatron instantaneous luminositymore »« less
Design and Implementation of the New D0 Level-1 Calorimeter Trigger

Journal Article Abolins, M; Adams, M; Adams, T; ...

Increasing luminosity at the Fermilab Tevatron collider has led the D0 collaboration to make improvements to its detector beyond those already in place for Run IIa, which began in March 2001. One of the cornerstones of this Run IIb upgrade is a completely redesigned level-1 calorimeter trigger system. The new system employs novel architecture and algorithms to retain high efficiency for interesting events while substantially increasing rejection of background. We describe the design and implementation of the new level-1 calorimeter trigger hardware and discuss its performance during Run IIb data taking. In addition to strengthening the physics capabilities of D0,more »« less

CDF trigger final balance: Offline resolution at low level selections to fight against Tevatron increasing luminosity

Conference Amerio, S - Nucl.Instrum.Meth.A617:250-253,2010

The CDF detector at Tevatron collider is at present the most long-lasting high energy physics experiment. Since its first data taking in 1992 it has produced many results of primary importance, such as the discovery of top quark and, more recently, the observations of Bs oscillations and single-top production. None of them would have been possible without a fast and efficient trigger system. Based on a three level architecture, the CDF trigger takes decisions on simple calorimetric and tracking objects and assures both high efficiency on signal events and low dead time. It reduces the data flow rate from 2.53more »« less
