TEL-2581
This is a hard vacuum, hot cathode X-ray tube designed for the Tel-X-Ometer. It has a copper target anode.
A thin concave bubble window of 0.25mm thickness is hand blown into the borosilicate glass envelope to transmit a high proportion of the characteristic radiation without recourse to other more expensive window techniques.
The cathode is a helical filament made of tungsten wire and the cathode/anode geometry provides a very small focal point.

The TEL-X-Driver comes complete with everything you need to automate data taking with the TEL-X-Ometer. Take data from 12 to 120 degrees with a maximum resolution of 0.05 degrees. The time per step is also adjustable, and can be as little as .1 sec. Scans can be obtained for all 4 of the crystals available for use with the TEL-X-Ometer, NaCl, LiF, KCl, and RbCl. An additional feature includes the ability to scan powders and foils.
TEL-2546/7
The majority of experiments which can be performed with the Tel-X-Ometer require the X-rays to be detected by a GM Tube in association with a Ratemeter or Scaler.
The typical intensities and recommended geometric conditions detailed in the laboratory manual are all relevant to the GM Tube TEL 2546/7.
TEL-582
A Kit of 26 components includes Collimators, Luminescent Screen, Film Cassettes and all the items necessary to perform more than 30 experiments.
Thin foils of Nickel, Copper, Cobalt and Zinc are included which are used to evaluate the Mass Absorption Coefficient. They are also used in conjunction with a Rotary Radiator which presents these 4 elements, and in addition Iron, Vanadium, Manganese and Chromium, to the primary X-ray beam. These 8 elements are sequential in the Periodic Table and secondary emission from them is analyzed to verify Moseley’s Law. The classical Bragg relationship can be established using large single crystals of Sodium Chloride and Lithium Fluoride and additionally Planck’s Constant can be derived from the minimum wavelength cutoff. Small minicrystals of LiF are included to record Laue and upper layer-line photographs. Finely divided LiF powder and copper wire strands can be used to demonstrate Debye-Scherrer analytical techniques with a special self-locating Powder Camera. The Powder Camera and Film Cassette included in TEL-582 have been designed for use with the Filmpacks.
TEL-583
This kit of 16 prepared elements is intended to supplement the Basic Kit.
For a more comprehensive study of Moseley’s Law four more thin foil slides are included. They are Iron, Vanadium, Manganese and Chromium. Together with the 4 slides in the Basic Kit, there can now be 8 thin foil slides to be used in conjunction with the 8 -element Rotary Radiator.
There are 5 vials of finely divided powders, 2 vials of drawn wire and large single crystals of Potassium Chloride and Rubidium Chloride. All of these materials are used in a carefully integrated study of the salient features of crystallographic analysis.
The Kit contains a Reciprocal Lattice Calculator for calculating at which angles of the GM tube carriage (2θ) reflections may be expected from each of the four single crystals.
TEL-584
This kit is also intended to supplement the Basic Kit. It is designed for teaching X-ray applications for nondestructive testing.
It includes 16 components with which the production and properties of X-rays can be studied. Additional emphasis is given to scattering, differential absorption and linear absorption coefficients; to the relationship between penetration, resolution and exposure time, accelerating voltage and tube current.
Experimental evidence of the importance of shielding materials, half thickness and radiation terminology are all highlighted through simple practical experience involving the components of the kit.
TEL-587
Rotation within the Powder Camera of single cyrstals and powders can be achieved using a Motorized Drive Unit which can be easily installed within the radiation scatter shield. The unit is electrically powered with its own switch and is supplied complete with a key to adjust the drive bevel position.
TEL-750/2
Film and Chemicals for 20 radiographs (38x35mm)
The teaching impact of processing photographic film in the classroom immediately after exposure and without a dark room is obvious.
High speed X-ray film is sealed in thin, black p.v.c. envelopes with two apertures to accept the injector tube of a syringe without admitting light. After exposure to beta-, gamma- or X-rays, film is developed rapidly by injecting the processing fluids in to the envelope which is thin enough to permit the necessary agitation. After processing is complete (about 2 minutes) the envelope is cut open and film removed with a special clip provided. Filmpaks 2 and 4 are supplied complete with syringe, injector tube, developer and fixer fluids and film clip.

Film and Chemicals for 12 Powder camera experiments

TEL-2591
The X-Ray Energy Detector, together with the TEL-X-Ometer, can perform x-ray Flouresence on most common alloys. MCA software is included, making it quick and easy to display a graph of intensity as a function of energy. Comparison of this graph to reference data easily identifies the components of any alloy. The software includes functions to deconvolute nearby peaks, as well as noise removal. Individual pulses can also be displayed as a voltage vs. time graph for investigation into the behavior of the detector.

A set of seven (7) Fluorescence samples for doing Xray Fluorescence experiments with the Tel-x-ometer.
TEL-2593
A NaI(Tl) scintillator attached to a miniature photomultiplier tube for use with the TEL-X-Ometer. When coupled with the TEL-X-Driver, its higher counting efficiency allows data to be taken from a wide variety of powder samples.
NaCl, LiF, KCl and RbCl Crystals for doing crystallography experiments with the Tel-X-Ometer.
TEL-2580M/2581
The Tel-X-Ometer x-ray machine and accessories have been designed specifically for use in teaching physics. Over thirty separate x-ray experiments (which begin with basic concepts of x-ray through complex experiments) are included in the laboratory manual provided with each system.
