Systems and Their Use,The purpose of this chapter is to give a general view of the instruments and systems used in the common radioisotope application practice. Therefore, it can be used as a guide for choosing the instrumentation required for a particular experiment. Detailed discussions of the main topics are given in subsequent chapters.

Preamplifiers,There are many different types of detectors used in nuclear industry, but almost all of them have one common characteristic: in the process of detecting the event they generate charge. Also, most exhibit high impedance levels. These facts must be borne in mind when deciding which type preamplifier is best suited to the experiment at hand.

Timing Circuits,The measurement of time, or rather of time intervals, plays an important role in a variety of experimental methods used in nuclear physics and in its applications in chemistry. The function of a timing circuit is to determine the length of a time interval that is specified by two electric pulses, a “start” and a “stop” pulse.
