DELTALINE Basic Packaged Scintillators



A Bicron Deltaline assembly is basically a piece of scintillator mounted in a low-mass metal container. Reflector material is packed between the scintillator and the container walls, and a K+ glass (or quartz) optical window is incorporated into one end. A wide variety of shapes and sizes can be produced. These detectors require user-supplied, externally-coupled photomultiplier tubes.

Deltalines are appropriate for certain experimental or manufacturing situations where different scintillator-PMT combinations may be required on a regular basis.

MONOLINE Scintillation Detector with Integrally Mounted PMT


In the Bicron Monoline assemblies, the photomultiplier tube is optically coupled directly to the scintillator. The scintillator is mounted in a container (usually of aluminum), and a mu-metal magnetic/light shield is fitted over the PMT. The scintillator container and mu-metal shield are sealed together to form a low-mass and light-tight housing for the detector.

This design usually yields better and more consistent pulse height resolution than others. Monolines are, therefore, the detectors of choice for spectroscopy and radcoisotope assay.

MULTILINE Scintillation Detector with Demountable PMT's


Bicron Multiline detector assemblies are scintillator-photomultiplier combinations that allow the removal of the photomultiplier tube or tubes without disturbing the scintillator package. The scintillator is mounted with appropriate reflector material in a low-mass metal container that has a glass or quartz optical window for each PMT. The magnetic light shield of each PMT is mechanically fastened to the flange or other mounting hardware in the scintillator container. Multiline detectors are usually 101.6mm (4”) in diameter and larger.

SQUARELINE Square Scintillation Detector with Demountable PMT



Bicron Squarelines are scintillator-photomultiplier combinations that allow the removal of the photomultiplier tube or tubes without disturbing the scintillator package. A square detector is a cost-effective alternate to the standard right cylinder. The cubic scintillator provides a 27% increase in volume over a comparable cylindrical scintillator. This increase in crystal volume substantially increases detector efficiency while still minimizing package size and shielding requirements.
