bragg driver
The Bragg Driver is a combination of hardware and software which allows the user to collect X-ray diffraction data, in combination with the X-ray Apparatus.
It provides the high voltage and counting circuitry for the Geiger–Müller Tube, whilst including a software program that allows the user to control the driver and collect data. The Bragg Driver includes a USB powered drive, a drive gear, a USB cable and a powder compressor.
Scans can be obtained for all crystals available in the Basic Equipment Set and the crystallography accessories. An additional feature is the ability to scan powders and foils. The software allows selection of scan angles, resolution and time per step.
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. This makes the drive ideal for scientists who wish to control and record their findings with greater precision and convenience.
