Flight performance of EXAM -- a balloon-borne detector to search for extragalactic antimatter
(Elsevier, 1994-06-01)
We describe the performance of the EXAM detector during its five hour balloon flight in 1988. EXAM is an experiment designed to search for cosmic rays of extragalactic origin which are made of antimatter. The EXAM technique ...
The mercedes-benz approach to [gamma]-ray astronomy
(Elsevier, 1988-02-01)
The sensitivity requirements for ground-based [gamma]-ray astronomy are reviewed in the light of the most reliable estimates of stellar fluxes above 100 GeV. Current data strongly favor the construction of detectors with ...
Muon trigger counters for a hadron collider experiment
(Elsevier, 1994-06-15)
We describe the design and performance of prototype trigger counters for the SDC muon system. The 1.0 x 48.7 x 178.7 cm scintillation counters feature compact light guides, use standard 2 in. phototubes, and provide good ...
Calorimeter trigger applications, training, and assessment of a feed-forward neural net
(Elsevier, 1992-06-15)
A feed-forward neural net technique is applied to trigger on decays in the high background environment of collisions at Ecm = 1.8 TeV. For the 1992 data run, we will install electronics into the CDF detector trigger using ...
The isochronous cyclotron and high-resolution nuclear spectroscopy
(Elsevier, 1970-02-15)
The practical limitations on high-resolution charged-particle spectroscopy imposed by the size and brightness of the effective source from an accelerator are discussed. Methods of measuring the characteristics of the source, ...
The central drift chamber for the high resolution spectrometer at PEP
(Elsevier, 1982-12-01)
The central drift chamger of the High Resolution Spectrometer (HRS) at PEP is described. Results on efficiency, calibrations and resolution are given for magnetic fields up to 1.6 T.
Isopin invariance in the reaction np --> [pi]0d
(Elsevier, 1971-10-01)
A measurement of the differential cross section for the reaction np--> [pi]0d has been made at the Lawrence Radiation Laboratory 184-inch cyclotron. A neutron beam with kinetic energies up to 720 MeV was incident on a ...
Are technicolor models compatible with a very heavy top quark?
(Elsevier, 1992-03-02)
We consider the phenomenological constraints on technicolor and extended technicolor (ETC) interactions required to give a realistic quark-lepton spectrum consistent with limits on flavor-changing neutral currents. Treating ...
Detour transitions in internal bremsstrahlung
(Elsevier, 1969-09-08)
The contribution of so-called detour transitions to the internal bremsstrahlung accompanying nuclear beta decay is calculated. These are transitions in which the nucleus rather than the electrons radiates the photon. It ...
Beyond the standard model
(Elsevier, 1989-06)
This conference emphasizes (in part) rare decays and symmetries. My talk examines possible ways to get at physics beyond the standard model from the perspective of rare decays, CP violation, and the collider frontier.
