Composition studies based on coincident air shower array and underground muon data ( )
2 editions published in 1991 in English and held by 2 WorldCat member libraries worldwide
We report on a final analysis of coincident underground muon data measured by the Soudan 1 proton decay detector and air shower data measured by an associated proportional tube array. These data were reported first at the 21st ICRC, Adelaide. We have done further analysis to determine the principal sources of systematic errors in such measurements, including different models of the primary interaction

A high current, short pulse electron source for wakefield accelerators ( )
2 editions published in 1992 in English and held by 2 WorldCat member libraries worldwide
Design studies for the generation of a high current, short pulse electron source for the Argonne Wakefield Accelerator are presented. An L-band laser photocathode rf gun cavity is designed using the computer code URMEL to maximize the electric field on the cathode surface for fixed frequency and rf input power. A new technique using a curved incoming laser wavefront to minimize the space charge effect near the photocathode is studied. A preaccelerator with large iris to minimize wakefield effects is used to boost the drive beam to a useful energy of around 20 MeV for wakefield acceleration experiments. Focusing in the photocathode gun and the preaccelerator is accomplished with solenoids. Beam dynamics simulations throughout the preaccelerator are performed using particle simulation codes TBCI-SF and PARMELA. An example providing a useful set of operation parameters for the Argonne Wakefield Accelerator is given. The effects of the sagitta of the curved beam and laser amplitude and timing jitter effects are discussed. Measurement results of low rf power level bench tests and a high power test for the gun cavity are presented and discussed
The electromagnetic calorimeter for the STAR experiment at RHIC ( )
2 editions published in 1992 in English and held by 2 WorldCat member libraries worldwide
The STAR detector at RHIC can be used both for searches for quark-gluon plasma and for high energy pp spin physics. An electromagnetic calorimeter is being planned which will be used for triggering on High pt direct gammas, e{sup {plus_minus}}, and the electromagnetic component of jets. Jets will be measured for both kinds of physics by using the electro-magnetic calorimeter and central TPC tracking. We describe some features of the fiber-tile calorimeter as it is presently being designed
Shower counter resolution scaling ( )
2 editions published in 1991 in English and held by 2 WorldCat member libraries worldwide
The EM shower counter for the SDC detector has a resolution expression containing two stochastic terms plus a constant term. Recent measurements clarifying the sources of these terms are presented here. 3 refs., 4 figs
Calibration of the LAMPF E-960 polarized target ( )
2 editions published in 1992 in English and held by 2 WorldCat member libraries worldwide
This note is mainly about the offline corrections for the target polarization measurements of E-960. For the sake of minimizing the number of separate documents, I have also included my recent thoughts about the target constant, in Sec. 6. The E-960 data-taking was done in two separate runs. With respect to having an operative NMR system, the runs dated from 27-AUG-87 to 10-DEC-87 and from 14-AUG-88 to 6-OCT-88. These runs will be referred to as the ''1987'' and ''1988'' runs, respectively. Because of the press of intervening projects, I have been unable until now to give my attention to the 1988 run of E-960. The information developed below in Secs. 3--5 is the result of my (belated) attempt to do so. A draft memo dated January 4, 1988 was previously distributed, which concerned the polarization correction factors for the 1987 run. I have reproduced the material from that memo in Sec. 2, for the sake of completeness. Also, since the analysis of the 1988 run has raised some questions about the appropriateness of the older analysis, I have augmented the material from that memo with some of the background observations and calculations that underlay its conclusions, to facilitate a comparison of the two runs. In Sec. 4 I have made a final synthesis of the observations made during the two runs, and it is there that one wig find my best estimate of the offline polarization corrections for both runs
Estimates of the neutron fluence for the SDC detector ( )
2 editions published in 1992 in English and held by 2 WorldCat member libraries worldwide
The high energy and high luminosity of SSC cause radiation problems to detectors. Almost all the radiation in the SDC detector comes from the 20 TeV on 20 Tev pp collisions. The design luminosity corresponds to 10⁸ collisions per second. This luminosity is maintained for 10⁷ seconds (one SSC year). It is important to know the radiation fields experienced by the tracking volume, calorimeter, electronics and the phototubes. The loss of light due to the radiation damage to the scintillators can adversely affect the physics performance of the calorimeter. Studies have been carried out earlier to estimate the radiation dose in the SDC detector. In this note we use ISAJET in combination with CALOR89 to make an accurate prediction of neutron fluence at the various locations of the SDC detector. The low energy neutron fluence is important because of their large activation cross sections. In CALOR89 the low energy neutron fluence is accurately estimated by MORSE code

Simultaneous observations of extensive air showers and underground muons at Soudan 2 ( )
2 editions published in 1991 in English and held by 2 WorldCat member libraries worldwide
We have built a small proportional tube air shower array on the surface above the Soudan 2 proton decay detector in Soudan, Minnesota, USA. This array, in coincidence with the underground detector, allows simultaneous surface and underground observations of high energy cosmic ray showers. These observations, still in their initial stages, may eventually be able to provide information about the composition of cosmic ray primaries in the ''knee'' region of the energy spectrum. 4 refs
Unix version of CALOR89 for calorimeter applications ( )
2 editions published in 1992 in English and held by 2 WorldCat member libraries worldwide
CALOR89 is a system of coupled Monte Carlo particle transport computer codes which has been successfully employed for the estimation of calorimeter parameters in High Energy Physics. In the past CALOR89 has been running on various IBM machines and on CRAY X-MP at Lawrence Livermore Lab. These machines had non-unix operating systems. In this report we present a UNIX version of CALOR89, which is especially suited for the UNIX work stations. Moreover CALOR89 is also been supplemented with two new program packages which makes it more user friendly. CALPREP is a program for the preparation of the input files for CALOR89 in general geometry and ANALYZ is an analysis package to extract the final results from CALOR89 relevant to calorimeters. This report also provides two script files LCALOR and PCALOR. LCALOR runs CALOR89 sequences of programs and EGS4 for a given configuration sequentially on a single processor and PCALOR concurrently on a multiprocessor unix workstation
Underground muons from the direction of Cygnus X-3 during the January 1991 radio flare ( )
2 editions published in 1991 in English and held by 2 WorldCat member libraries worldwide
Muons recorded in the Soudan 2 underground nucleon decay detector from January 1989 to February 1991 have been examined for any correlation with the radio flares of Cyguns X-3 observed during this period. On two nearby days during the radio flare of January 1991 a total of 32 muons within 2.0° of the Cyguns X-3 direction were observed when 11.4 were expected
