An electron beam moves toward a cathode ray tube screen, which is 50 cm away from the negative electrode. The electrons are accelerated by a potential difference of 18 kV. Estimate the maximum displacement of the electron beam caused by Earth's magnetic field. The average magnetic field at the surface of Earth is roughly BE = 45×10−6T. Δz = ?

The electrons in a cathode ray tube are emitted by a hot filament cathode and are accelerated by an electric field applied between the cathode and two orthogonal pairs of parallel plate electrodes. The beam passes through the gap between the electrodes and can be deflected up and down, or left and right if the parallel plates are appropriately biased. As the electrons pass through the electrodes, their kinetic energy increases. Assume the electrons are emitted from the cathode with...

X-ray filter An X-ray beam from a tube with molybdenum anode (?=42) at an acceleration voltage of ?=60 kV contains, besides the braking continuum, a distinct ?? peak at 0.71 Å and a smaller ?? peak at 0.63 Å. To filter out the ?? line for diffraction experiments, a zirconium filter (?=40) can be used. Justify this with the help of Mosley's law and draw the X-ray spectrum of molybdenum superimposed with the absorption effect of zirconium. Is the main...

In the “old days”, televisions were made from Cathode Ray Tubes whereby a beam of electrons rapidly swept across the inside of the screen as a result of strategic deflections from magnetic fields acting on the beam. Suppose that Frank has a massive 2000 inch TV in which the image has to be updated 100 times per second (to minimize the appearance of “flicker”) and that there are 100,000 rows. (a) Show that the electron beam moves across the screen...
