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 ...
Granite, a new very high energy gamma-ray telescope
(Elsevier, 1990-03)
A international collaboration of astrophysicists plan to construct a new 10-meter diameter gamma-ray Cerenkov telescope at the Whipple Observatory on Mt. Hopkins in Arizona. By operatin in coincidence with the original ...
Curvature and flatness in a Brans-Dicke universe
(Elsevier, 1994-06-27)
The evolution of a universe with Brans-Dicke gravity and nonzero curvature is investigated here. We find solutions to the equations of motion during the radiation dominated era. In a Friedman-Robertson-Walker cosmology we ...
Decay angular distributions of p[pi]- states formed in diffraction dissociation of neutrons on carbon
(Elsevier, 1972-08-01)
We present decay angular distributions of the p[pi]- system formed from the interactions of 25-30 GeV/c neutrons on a carbon target. The data are studied as afunction of t', which allows a partial separation of coherent ...
Diffraction dissociation of neutrons in the reaction dp --> ppp[pi]- at 25 GeV/c
(Elsevier, 1974-09-18)
We observe the reaction dp --> pspec (p[pi]-)p in a bubble chamber exposure at 25 GeV/c incident deuteron momentum. The (p[pi]-) system with invariant mass below 2.0 GeV is interpreted as neutron diffraction dissociation. ...
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 ...
A description of drift chambers used in a Fermilab experiment
(Elsevier, 1976-11-01)
We give a detailed description of the drift chamber system used in a charm search at Fermilab. All important aspects of design and performance are discussed.
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 ...
Inclusive and semi-inclusive pion production in pp collisions at 102 and 400 GeV/c
(Elsevier, 1976-04-26)
We present a comparative study of inclusive and semi-inclusive pion production in pp collisions at 102 and 400 GeV/c. In particular, we examine the correlation between transverse and longitudinal momentum variables and the ...
