X-Ray system is designed to be an excellent tool for teaching and learning
about the properties and uses of x-rays. It consists of several core pieces, the TEL-X-Ometer
and the TEL-X-Driver, and several accessories: a Geiger Müller tube, a NaI(Tl) Scintillator,
and a X-Ray Energy Detector. The primary function of the system is x-ray diffraction, but it
is also useful for x-ray fluorescence, for making radiographs, and for investigating the basic
properties of x-rays. Under normal operation, the TEL-X-Ometer produces a narrow beam
of x-rays. The majority of this beam is not effected by any experiment being performed, and
is absorbed by the lead backstop located at the front of the unit. Any scattered radiation is
absorbed by the plastic Scatter Shield which is made of a chlorinated plastic which has strong
x-ray absorption. The unit is also designed with safety in mind. Two separate safety circuits
ensure that the scatter shield is in place, and a third safety circuit ensures that the leaded
glass dome is in place. The safety systems of the TEL-X-Ometer meet all FDA regulations
for sale in the United States. These regulations are available on the FDA’s website.
This manual is divided into two parts. Part One deals with the commissioning, maintenance
and operation of the TEL-Atomic X-Ray System. Part Two contains over 25 suggested
experiments, not all of which may be performed without some optional accessories. An
effort is made, however, to make concepts accessible (if possible) regardless of the available
equipment.
