Physics requirements for LHC/SSC calorimetry

Description: The goal of the next generation of collider detectors is to study the origin of electroweak symmetry breaking. The mass scale for this study is roughly 1 TeV. No matter what the details of the mechanism, one can be confident that new phenomena will occur, since weak interactions become strong, i.e., violate partial wave unitarity, at that mass scale. The partial wave amplitude for ee{yields} WW scattering is; ao{approximately}4{phi}/{alpha}{sub w}(M{sub w}/M){sup 2}, ao{approximately}1 if M {ap… more

Source calibrations and SDC calorimeter requirements

Description: Several studies of the problem of calibration of the SDC calorimeter exist. In this note the attempt is made to give a connected account of the requirements on the source calibration from the point of view of the desired, and acceptable, constant term induced in the EM resolution. It is assumed that a local'' calibration resulting from exposing each tower to a beam of electrons is not feasible. It is further assumed that an in situ'' calibration is either not yet performed, or is unavailable du… more

Simple model of calorimeter sampling response in a magnetic field

Description: The fact that plastic scintillator ``brightens`` in the presence of a magnetic field has been known for some time. Recently, measurements have been extended to larger field strengths ( < 20 T ) and a saturation of the effect was observed for fields > 2.5 T. Thus the active element in a sampling calorimeter may be expected to have a signal increase of {approx} 6-8 % when immersed in fields of strength > 2.5 T. This brightening of the scintillator is independent of the orientation of the field. I… more

Effect of dead material in a calorimeter

Description: The existence of dead material in any practical calorimeter system is simply a fact of life. The task for the designer, then, is to understand the impact on the Physics in question, and strive to minimize it. The aim of this note is to use the ``Hanging File`` test data, which has fined grained individual readout of about 100 depth segments, to explore impact of dead material on the mean and r.m.s. of the hadronic distribution. The amount and location of the dead material is varied. It importan… more

Infrared NDT methods applied to solar cell and panel characterization

Description: Infrared nondestructive testing (NDT) methods are described that have a good potential for providing valuable data concerning solar cell or panel characteristics without requiring contact with the photovoltaic device. Preliminary tests with cells and panels were conducted and the infrared NDT results are presented and discussed. (MHR)

Improved oil recovery in fluvial dominated deltaic reservoirs of Kansas - Near-term. Annual report, June 18, 1993--June 18, 1994

Description: Common oil field problems exist in fluvial dominated deltaic reservoirs in Kansas. The problems are poor waterflood sweep and lack of reservoir management. The poor waterflood sweep efficiency is due to (1) reservoir heterogeneity, (2) channeling of injected water through high permeability zones or fractures, and (3) clogging of water injection wells with solids as a result of poor water quality. In many instances the lack of reservoir management is due to lack of (1) data collection and organi… more

Improving reservoir conformance using gelled polymer systems. Quarterly technical progress report, July 1, 1995--September 30, 1995

Description: Objectives of this project are to identify and develop gelled polymer systems which have potential to improve reservoir conformance to fluid displacement systems; determine the performance of these systems; and to develop methods to predict the capability of these systems to recover oil from petroleum reservoirs. Gels investigated include an aqueous polysaccharide, a chromium-polacrylamide, and an aluminium citrate-polyacrylamide system.

Test of the DEP hybrid photodiode in 5 Tesla Magnet

Description: The CMS detector is designed so that the tile/fiber hadronic calorimeter (HCAL) is immersed in a 4 Tesla magnetic field. The Hybrid Photodiode (HPD) will be used as the photodetector. Below we present the experiment data which we obtained on the HPD behavior in a magnetic field.

In situ permeability modification using gelled polymer systems. Topical report, June 10, 1996--April 10, 1997

Description: Results from a research program on the application of gelled polymer technology for in situ permeability modification are presented in this report. The objective of this technology when used with displacement processes such as waterflooding is to reduce the permeability in fractures and/or high permeability matrix zones to improve volumetric sweep efficiency of the displacement process. In production wells, the objective is to reduce water influx. The research program is focused on five areas: … more
