Response function of thallium-activated sodium-iodide scintillation counters

Study on Growth and Optical, Scintillation Properties of Thallium Doped Cesium Iodide-Scintillator Crystal

Single crystal of Thallium doped cesium Iodide –Scintillator crystal was grown using vertical Bridgeman technique. The grown crystal was included for cutting and polishing for the characterization purpose and this crystal was studied by optical transmission properties, photo luminescence and thermally luminescence characteristics. Gamma-ray detectors were fabricated using the grown crystal that...

A Time Compensator for Large Scintillation Counters*

A circuit is described which develops time-invariant pulses for large scintillation trigger counters. For a 8.56 ft long counter, a unit capable of f 22 nsec range is described; the constancy of delay of output for this unit over the full delay range is typically & 400 psec. * Work supported by the U. S. Atomic Energy Commission. (Submitted to Nucl. Instr . & Methods. ) 1 D Introduction One of ...

Scintillation Counters for the DØ Muon Upgrade

We present the results of an upgrade to the DØ muon system. Scintillating counters have been added to the existing central DØ muon system to provide rejection for cosmic ray muons and out-of-time background, and to provide additional fast timing information for muons in an upgraded Tevatron. Performance and results from the 1994–1996 Tevatron run are presented. Submitted to Nuclear Instruments ...

Response of a Sodium - Iodide Scintillation Spectrometer to 10 - to 20 - Million - Electron - Volt Electrons and X - Rays

The response of a la rge-crystal sodium-iodide spectrometer was studied fo[' individual monoenergetic electrons extracted from a 50-million-electron-volt betatron operatcd between 1 a nd 20 Mev. The energy resolut ion with crystals 5 inches in diameter by 4 inches in length a nd 5 inches in diameter by 9 inches in length reaches its optimum value fo r electrons of 6 Mev where t he total width o...
