β-Particle Magnetic Deflection Experiment – Supplementary Pictures

β-Particle Magnetic Deflection Experiment

The book’s Figure 65 shows our β-particle magnetic deflection setup.  It consists of a 90Sr disc source of beta particles, two copper washers to collimate the beam, and GM tubes placed at 0º and 90º to the β-particle beam. A sufficiently strong magnetic field (around 800 Gauss = 0.08 Tesla) provided by a permanent magnet bends the beam so much that it is easily detected at a right angle (notice the meter needles in the pictures above).
