Early History of X Rays - SLAC

The rays cast shadows, and were deflected by magnetic fields, but appeared to be immune to the ef-fects of static electric forces. As was to be characteristic of the new ray physics to come—the phys-ics of cathode rays, X rays, alpha rays, beta rays, gamma rays, and N rays— the nature of the cathode rays was in dispute, the British favoring ...

the rays spread out over a greater area. Over a long exposure to light rays at the various angles, predict which angle would likely have the highest temperature reading. Why? At a higher angle the surface area should have the highest temperature because the rays are concen-trated in a smaller area. What natural factors cause the Sun’s rays to ...

Production of X-rays and Interactions of X-rays with Matter

Production of X-rays and Interactions of X-rays with Matter Goaz and Pharoah. Pages 11-20. Neill Serman Electrons traveling from the filament ( cathode) to the target (anode) convert a small percentage (1%) of their kinetic energy into x-ray photons by the formation of bremsstrahlung and characteristic radiation.

X-Ray Diffraction (XRD)

X-rays Hence, X-rays can be used for the study of crystal structures Neutrons and Electrons are also used for diffraction studies from materials. Neutron diffraction is especially useful for studying the magnetic ordering in materials Beam of electrons Target X-rays A accelerating charge radiates electromagnetic radiation
