Single Channel Analyzer and Processor


System shown with SP78W-1 well detector

The ST450 Scintillation SCA provides a convenient interface between a scintillation detector and counter/timer for detecting gamma rays over a defined energy range. Front panel controls allow selection of an energy window so that only gamma-rays within a specific energy range are counted. The unit contains all of the necessary support for connecting a scintillation detector and includes high voltage and built-in preamplifier/amplifier. When used with the SPECTECH ST360 Radiation Counter, the system offers computer interfacing capability. This including control, data transfer and automatic ramping of the baseline to produce a full energy spectrum of the emissions. In addition to the ST360 connection, the instrument includes an SCA output for use with other counters and an amplifier output for signal monitoring.

When used with the ST360 Radiation Counter, the STX software provides connection to either a PC or Macintosh computer allowing control of preset time, preset count and baseline ramping. Data is stored in a spreadsheet compatible file for exporting to Excel or other spreadsheet program. The data may then be graphed to display the energy spectrum of the sample being measured for isotope identification.

Specifications. Built-in preamplifier/amplifier for direct connection to PMT anode signal. Bipolar shaping, 1µsec. peaking time. Gain controls, fine 0.5-1.5, coarse 2-64. Baseline control 0-100%. Window control 1-20%. High Voltage control, 200-1200v positive. 1mA maximum, fully regulated. Integral and differential modes. External Scan mode when used with ST360 Radiation Counter and STX software. Power requirement, 16v a/c from line transformer supplied. (Specify 110 or 220VAC at time of ordering.)

Scintillation Counting System

The ST360W is a versatile, general purpose counter/timer for use with either a scintillation or GM detector. The unit features a large, 6-digit LED display with selection for counts, time, countrate, high voltage or alarm level. USB and serial outputs are included for connecting to an optional PC or Macintosh computer for data transfer and automated operation if required.
