Mobility of Tritium in Engineered and Earth Materials at the NuMIFacility, Fermilab: Progress report for work performed between June 13and September 30, 2006

Description: This report details the work done between June 13 andSeptember 30, 2006 by Lawrence Berkeley National Laboratory (LBNL)scientists to assist Fermi National Accelerator Laboratory (Fermilab)staff in understanding tritium transport at the Neutrino at the MainInjector (NuMI) facility. As a byproduct of beamline operation, thefacility produces (among other components) tritium in engineeredmaterials and the surrounding rock formation. Once the tritium isgenerated, it may be contained at the source lo… more

Two Jet Production at CDF

Description: CDF (Collider Detector at Fermilab) is a full-coverage magnetic detector studying p{bar p} collisions at the {radical}s = 1.8 TeV Tevatron Collider. The experiment has collected a handful of demonstration events towards the end 1985, and had its first significant run in spring 1987. Most of this run was operated with a 'buffet trigger', one stream of which was an inclusive large-E{sub t} trigger. Large E{sub t} (E{sub t} >50 GeV) events at the Tevatron show an increasingly dominant component… more

B Physics at the Tevatron

Description: After a five year upgrade period, the Fermilab experiments CDF and D0 are taking high quality data in Run II of the Tevatron Collider. We report on the start-up of both detectors and present a selection of first B physics results from the Tevatron. We also compare different B hadron producers such as the {Upsilon}(4S) with the hadron collider environment and discuss general features of B physics at a hadron collider.

CDF Run IIb Silicon Vertex Detector DAQ Upgrade

Description: The CDF particle detector operates in the beamline of the Tevatron proton-antiproton collider at Fermilab, Batavia, IL. The Tevatron is expected to undergo luminosity upgrades (Run IIb) in the future, resulting in a higher number of interactions per beam crossing. To operate in this dense radiation environment, an upgrade of CDF's silicon vertex detector (SVX) subsystem and a corresponding upgrade of its VME-based DAQ system has been explored. Prototypes of all the Run IIb SVX DAQ components ha… more

Event builder and level 3 at the CDF experiment

Description: The Event Builder and Level3 systems constitute critical components of the DAQ in the CDF experiment at Fermilab. These systems are responsible for collecting data fragments from the front end electronics, assembling the data into complete event records, reconstructing the events, and forming the final trigger decision. With Tevatron Run IIa in progress, the systems have been running successfully at high throughput rates, the design utilizing scalable architecture and distributed event processi… more

The new Tevatron beam position monitor front-end software

Description: The Tevatron is a proton anti-proton accelerator collider operating at the Fermi National Accelerator Laboratory. The machine is currently delivering beam for the CDF and D0 experiments, which expect increasing luminosity until the conclusion of Run II, planned for 2009. The Laboratory defined a plan for achieving higher luminosity, and one of the tasks is the upgrade of the accelerator's beam position monitor (BPM). The Tevatron was built during the early eighties and some of its control syste… more

Recent results in high pT physics from CDF

Description: The authors present the most recent high p{sub T} results from the CDF experiment using p{bar p} collisions at {radical}s = 1.96 TeV produced at the Tevatron Collider at Fermilab. They summarize results in electroweak physics, top physics and searches for physics beyond the Standard Model. Many measurements of important signals like W boson, Z boson, and the top quark have been reestablished. Taking advantage of the increase in energy and detector upgrades, these measurements already begin to b… more

A Synchrotron phase detector for the Fermilab Booster

Description: A synchrotron phase detector is diagnostic tool for measuring the relative phase between the accelerating field and the beam. One has been implemented in the Fermilab Booster. This is probably the first time for the Booster that the accelerating voltage seen by the beam can be experimentally determined from the information of the synchrotron phase measurement and the existing total rf accelerating voltage (RFSUM) signal without using the calculated synchrotron phase values.

Data acquisition and analysis for the Fermilab Collider RunII

Description: Operating and improving the understanding of the Fermilab Accelerator Complex for the colliding beam experiments requires advanced software methods and tools. The Shot Data Acquisition and Analysis (SDA) has been developed to fulfill this need. The SDA takes a standard set of critical data at relevant stages during the complex series of beam manipulations leading to {radical}(s) {approx} 2 TeV collisions. Data is stored in a relational database, and is served to programs and users via Web based… more

Study of the heavy flavor content of jets produced in W events at the Tevatron collider

Description: We present a detailed study of the heavy flavor content in the W + jet data sample collected with the CDF detector during the 1992-1995 collider run at Fermilab. Rates of heavy flavor jets, identified via the observation of secondary vertices or semileptonic decays of b and c quarks, are in good agreement with a standard model simulation including production of the top quark. An exception is the number of events in which a single jet has both a secondary vertex and a semileptonic decay tag. In … more

B(c) and Excited B States: A Tevatron Review

Description: In this paper recent results from the CDF and D0 experiments on heavy flavor spectroscopy are reported. Both experiments are using up to 1.1 fb{sup -1} of data delivered by the Tevatron proton-antiproton collider at the Fermi National Accelerator Laboratory, Batavia, IL, USA. The CDF and D0 detectors are described in references [1,2].

Top quark physics at CDF

Description: The existence of the top quark, discovered by CDF and D0 in 1995, has been re-established in the burgeoning dataset being collected in Run 2 of the Tevatron at Fermilab. Results from CDF on the top quark production cross section and top quark mass are consistent with the Standard Model expectations. The well-characterized top data samples will make it possible in the future to probe further for new physics in the top quark sector.

$B$ mixing and lifetimes at the Tevatron

Description: The Tevatron collider at Fermilab provides a very rich environment for the study of b-hadrons. Both the D0 and CDF experiments have collected a sample of about 1 fb{sup -1}. they report results on three topics: b-hadron lifetimes, polarization amplitudes and the decay width difference in B{sub s}{sup 0} {yields} J/{psi}{phi}, and B{sub s}{sup 0} mixing.

Aperture studies for the AP2 anti-proton Line at Fermilab

Description: The AP2 beamline transports anti-protons from the production target to the Debuncher ring. For many years the observed aperture has been smaller than that estimated from linear, on-energy optics. We have investigated possible reasons for the aperture restriction and have identified several possible sources, including residual vertical dispersion from alignment errors and chromatic effects due to very large chromatic lattice functions. We discuss the possible sources, suggest some remedies, and … more

Prospects in CP violation measurements at the Tevatron Collider

Description: The Fermilab Tevatron Collider is currently the most copious source of b-hadrons, thanks to the large b{bar b} production cross-section in 1.96 TeV p{bar p} collisions. Recent detector upgrades allow for a wide range of CP violation and flavor-mixing measurements that are fully competitive (direct asymmetries in self-tagging modes) or complementary (asymmetries of B{sub s} and b-baryons decays) with B-factories. In this paper we review some recent CP violation results from the D0 and CDF II Col… more

Tevatron Run II luminosity, emittances and collision point size

Description: The authors compare the Tevatron luminosity as measured by the CDF and D0 experiments with that computed from machine characteristics. They also compare the CDF measurements for the size of the interaction region with that predicted by machine parameters. Although these results are still preliminary, they show promise as a useful crosscheck of the instrumentation and our understanding of the Tevatron machine characteristics.
