Title: Recent developments in silicon calorimetry

Abstract

We present a survey of some of the recent calorimeter applications of silicon detectors. The numerous attractive features of silicon detectors are summarized, with an emphasis on those aspects important to calorimetry. Several of the uses of this technology are summarized and referenced. We consider applications for electromagnetic calorimetry, hadronic calorimetry, and proposals for the SSC.

  • We present a survey of some of the recent calorimeter applications of silicon detectors. The numerous attractive features of silicon detectors are summarized, with an emphasis on those aspects important to calorimetry. Several of the uses of this technology are summarized and referenced. We consider applications for electromagnetic calorimetry, hadronic calorimetry, and proposals for the SSC.
  • Brief discussions are given of the work that has been done on the suppression of the slow component in BaF{sub 2}, the developments in the understanding of undoped CsI, and the properties of the new scintillator CeF{sub 3}. The properties of the Cherenkov radiator PbF{sub 2} along with test beam results are presented. Monte Carlo simulations indicate that, with the addition of a small amount of scintillator, PbF{sub 2}, can be made hadron compensating off-line so that the resolution of a compensating hadron calorimeter will not be degraded by its presence. 14 refs., 6 figs., 4 tabs.
  • A need for faster plutonium calorimetric assay measurments at several DOE plutonium facilities has been established. A method for reducing the measurement time of an ANL air-bath bulk calorimeter to less than 20 minutes for bulk samples was proposed, and a field test to gather additional data and develop the best measurement protocol was conducted. Improvements in the sample preheating, data acquisition hardware, and prediction algorithm software were made to optimize the performance of an ANL air-bath calorimeter for fast measurements. The modified calorimeter was tested at ANL and at Rocky Flats on a limited number of samples in themore » 1-4 watt range. The measurement time was 17-18 minutes with a precision of less than 1%. A new air-bath bulk calorimeter with a lower power range and larger sample diameter incorporating the fast measurement technology has been proposed. The new instrument could be ready for testing in 12 months.« less
  • A variety of techniques may be used for photovoltaic energy systems. Concentrated or not concentrated sunlight may be employed, and a number of materials can be used, including silicon, gallium arsenide, cadmium sulfide, and cadmium telluride. Most of the experience, however, has been obtained with silicon cells employed without sunlight concentration. An industrial base exists at present for producing solar cells at a price in the range from $15 to $30 per peak watt. A major federal program has the objective to reduce the price of power provided by silicon solar systems to approximately $1 per peak watt in themore » early 1980's and $0.50 per watt by 1986. The approaches considered for achieving this objective are discussed.« less
  • The challenges for calorimeter performance in the next decade are reviewed. Some new ideas for calorimeters are described: (1) the test of a parallel plate calorimeter; (2) the use of vacuum photodiodes for calorimeters operating in a magnetic field; (3) the attempt to build high pressure gas sealed tubes as ion chambers in hadron calorimeters; (4) the progress in the attempt to mold plastic loaded with heavy metal for the inert material in gas calorimeters; and (5) the use of the limited streamer mode in calorimeters.
