Efficient algorithms for estimating the width of nearly normal distributions
(Elsevier, 1983-06-15)
Typical physics data samples often conform to Gaussian distributions with admixtures of more slowly varying backgrounds. Under such circumstances the standard deviation is known to be a poor statistical measure of distribution ...
The performance of "Virtual Phase" CCDs as detectors of minimum-ionizing particles
(Elsevier, 1987-10-01)
The Texas Instruments "Virtual Phase" CCD has been the basis of an ambitious design for a precision vertex detector to be used at the Stanford Linear Collider. The performance of this chip shows promise for future use in ...
The operation of a pressurized ultraviolet photoionization threshold cherenkov counter
(Elsevier, 1981-07-15)
We have successfully tested an ultraviolet photoionization Cherenkov counter in a 10 GeV/c pion beam. The counter has been tested to 11 atm pressure for use as a [pi]-K separator. The design and operation of the counter ...
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 ...
Response of high resolution drift tubes to relativistic heavy ions
(Elsevier, 1985-11-15)
We report the results of various tests undertaken in a program to develop a drift tube hodoscope for a cosmic ray balloon experiment intended to search for extragalactic antimatter. Included are studies of mechanical ...
Charge resolution of plastic track detectors used to identify relativistic nuclei
(Elsevier, 1985-02)
We present measurements of charge resolution in the plastic track detectors CR39(DOP) and Tuffak polycarbonate over the region 10Z/ [beta] GeV/u139La, 1.45 GeV/u84Kr, and 1.70 GeV/u56Fe produced by nuclear interactions ...
The Mark II detector for the SLC
(Elsevier, 1989-08-20)
The Mark II detector has been upgraded in preparation for its role as the first detector to take data at the Stanford Linear Collider. The new detector components include the central drift chamber, the time-of-flight system, ...
Cosmic ray antimatter from supersymmetric dark matter
(Elsevier, 1986-01-20)
In this paper we study the antiproton, positron and gamma-ray fluxes resulting from the annihilation of supersymmetric dark matter in our galactic halo. We show that the requirement of closure imposed by inflationary ...
Coulomb displacement energies and decay widths of isobaric analog states from Sm(3He, t) at [theta] = 0[deg]
(Elsevier, 1983-06-27)
The 144,147,148,149,150,154Sm(3He, t)144,147,148,149,150,152,154Eu reactions leading to ground-state isobaric analog states (IAS) have been studied at [theta] = 0[deg] and E(3He) = 45.9 MeV. The Coulomb displacement energies ...
A water Cherenkov counter sensitive to nonwaveshifted ultraviolet Cherenkov photons
(Elsevier, 1986-11-15)
We describe a prototype water Cherenkov counter which has been built and tested with relativistic cosmic ray muons. An analysis of the expected photoelectron yield is described. The predicted result of 315 +/- 31 photoelectrons ...
