A hand-holdable, battery-operated, microprocessor-based spectrometer gun includes a low-power matrix display and sufficient memory to permit both real-time observation and extended analysis of detected radiation pulses. Universality of the incorporated signal processing circuitry permits operation with various detectors having differing pulse detection and sensitivity parameters. |

DETAILED DESCRIPTION To achieve the foregoing and other objects, and in accordance with the purposes of the present invention, as embodied and broadly described herein, the apparatus of this invention may comprise a detector section, having a radiation detector, a photomultiplier tube and a high voltage power supply, an input processing section having amplifiers, signal processing circuitry and an A/D converter, a digital processing section having a microprocessor with control and data memories, a display section having an LCD data matrix display and an alphanumeric LCD mode-of-operation display, a control section having a keyboard and other switches to control display and other functions and a battery section.
Preferably CMOS and other low power circuitry is used with Ni-Cds batteries packaged together in a light hand-holdable single package for extended field application.
One advantage of the present invention is that its utilization of CMOS components, digital circuitry, and LCD displays permit extended field operation with a small rechargeable battery supply.
Another advantage of the present invention is that its pulse amplification and digital storage and display circuitry may be used with a diversity of detectors to monitor a variety of gamma and other radiation pulses.
Still another advantage of the present invention is that its microprocessor's data memory permits extended analysis as well as real-time monitoring of detected radiation pulses.
Additional objects, advantages and novel features of the invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention.
The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
