I. INTRODUCTION

Description

The Gamma Scientific Model G-3 Photometer is a self-contained high sensitivity

laboratory instrument. Its detector is a photomultiplier with an S4 photosurface.

The adjustable high voltage power supply and a sensitive FET electrometer am-

plifier in conjunction with a variable neutral density shutter and 5 to 1 scale

expansion provide for maximum range. The G-3 is supplied with a detachable

high spatial resolution flexible fiber optic probe. Other features include rugged

design, ease of operation and a built-in shutter for zeroing. State-of-the-art

solid state components are used throughout the unit. The "Se nsitivity Control"

and "Zero Control" are both 10-turn potentiometers for fine vernier adjustment.

The instrument is housed in a fully isolated and insulated shock-proof and shatter-

proof case. There is a 1/4-20 thread connection on the bottom of the case for

tripod or optical bench mounting.
