TEL TS2580B-2 Basic X-Ray System

With the Basic X-Ray System students can perform over 10 x-ray detection experiments using photographic techniques and the Geiger-Muller tube. Students can investigate Laue x-ray diffraction, Bragg diffraction on single crystals, and x-ray emission. Properties of x-ray, such as rectilinear propagation, inverse square relationship, and penetration and absorption can also be shown.

TEL 25819 TEL-X-Ometer® With Tube & TEL-X-Driver

TEL-X-Ometer

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.

The Tel-X-Ometer is a spectrometer which can easily be adapted to become:

  1. A Broad Beam of X-rays for analysis of the General Properties of X-rays.
  2. A Single Bragg Diffractometer having a scale accuracy of 5 minutes of arc.
  3. A Powder Camera for Debye/Scherrer experiments to an accuracy of 30 minutes of arc.
  4. A fluorescent Radiation Emitter for a study of the Moseley Theory that every element is characterized by its Atomic Number.
  5. An Experimental region for the mounting of innovative studies of the teacher’s choice.

The x-ray machine can be carried easily by one person and set up on a laboratory table with all accessories conveniently at hand. Calibrations and scales on the x-ray machine and accessories are clear and easy to read, even when teaching to a group of students around the table. The TEL-X-Ometer now comes with the TEL-X-Driver which allows the unit to be controlled with a computer.

We have built user safety into each machine through a number of safety switches and protective x-ray absorbing shields. Safety switches prevent operation if all covers are not closed and in the operating position. In addition, a keyed master switch gives the instructor complete control over the machine’s operation.

Choose one of our three TEL-X-Ometer Systems to get all of the accessories to perform a series of experiments. You may also put together an individualized system by starting with the basic x-ray machine and x-ray tube and adding accessories. The Tel-X-Ometer x-ray machine and accessory components are individually priced and can be purchased separately.

TEL 2590 TEL-X-Driver

The TEL-X-Driver Accessory for the TEL-X-Ometer

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.(Sample Data) An additional feature includes the ability to scan powders and foils.

The TEL-X-Driver is USB powered. A GM tube can be connected directly to this unit, negating the need for an additional scalar or ratemeter. Software allows selection of scan angles, resolution, and time/step. Data is automatically saved every 30 seconds thus preventing the loss of data during a long scan in the event of a power failure. Once the experiment is completed the software permits zoom-in on the data and the facility to add comments to the file. Data can be exported to a spreadsheet for further analysis.

Manual and software included.

Please note that the auxilary slide carriage can not be used concurrently with the TEL-X-Driver. Most experiments can be adapted to work without the auxilary slide carriage. If you would like information on performing a specific experiment without the auxilary slide carrige, please contact us.

TEL 582 Basic Accessory Kit

TEL 582 BASIC ACCESSORY

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 Kit 582 have been designed for use with the Filmpaks.

TEL 2581 Miniature x-ray Tube

TEL 2581 MINIATURE X-RAY TUBE

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.

Continuous rating:
30kV, 80 µA
Heater supply:
4V 1A
Dimensions:
100mm long, 32mm diameter
Mounting:
B13G type

TEL 750/2 and TEL 750/4 Filmpaks

TEL 750/2 AND TEL 750/4 FILMPAKS

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.

X-ray film available in two sizes:

TEL 750/2 Film and Chemicals for 20 radiographs (38x35mm)
$227.00
TEL 750/4 Film and Chemicals for 12 Powder camera experiments
$217.00

TEL 2546/7 Geiger-Muller Tube With Holder

TEL 2546/7 GEIGER-MULLER TUBE WITH HOLDER

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. The Ratemeter TEL 2807 and the Scaler TEL 2806 have been designed to monitor Tel-X-Ometer experiments with both simplicity and maximum didactic impact.
