Gas Mixtures For Gas-Filled Radiation Detectors
US Patent:
4309307, Jan 5, 1982
Filed:
Mar 28, 1980
Appl. No.:
6/134815
Inventors:
Loucas G. Christophorou - Oak Ridge TN
Dennis L. McCorkle - Knoxville TN
David V. Maxey - Knoxville TN

International Classification:
C09K 300, H01J 3928, H01J 3930
US Classification:
252372
Abstract:
Improved binary and ternary gas mixtures for gas-filled radiation detectors are provided. The components are chosen on the basis of the principle that the first component is one molecular gas or mixture of two molecular gases having a large electron scattering cross section at energies of about 0. 5 eV and higher, and the second component is a noble gas having a very small cross section at and below about 1. 0 eV, whereby fast electrons in the gaseous mixture are slowed into the energy range of about 0. 5 eV where the cross section for the mixture is small and hence the electron mean free path is large. The reduction in both the cross section and the electron energy results in an increase in the drift velocity of the electrons in the gas mixtures over that for the separate components for a range of E/P (pressure-reduced electric field) values. Several gas mixtures are provided that provide faster response in gas-filled detectors for convenient E/P ranges as compared with conventional gas mixtures.

Abstract:
Improved binary and tertiary gas mixtures for gas-filled particle detectors are provided. The components are chosen on the basis of the principle that the first component is one gas or mixture of two gases having a large electron scattering cross section at energies of about 0. 5 eV and higher, and the second component is a gas (Ar) having a very small cross section at and below aout 0. 5 eV, whereby fast electrons in the gaseous mixture are slowed into the energy range of about 0. 5 eV where the cross section for the mixture is small and hence the electron mean free path is large. The reduction in both the cross section and the electron energy results in an increase in the drift velocity of the electrons in the gas mixtures over that for the separate components for a range of E/P (pressure-reduced electron field) values. Several gas mixtures are provided that provide faster response in gas-filled detectors for convenient E/P ranges as compared with conventional gas mixtures.
