====== Electric Fields II: Acceleration and Deflection of Electrons ====== ---- ==== Common area ==== * Magnets (can be used to divert the beam if there is a dead spot on the CRT screen) * "Exposed" CRT, //if available// (can be used to show the inside workings, especially the deflection plates) * Extra spare parts, especially the following: * Multimeters * CRT * 24 V power supply * 500 V power supply | {{:phylabs:lab_courses:phys-120_130-wiki-home:winter-experiments:electric-fields-ii_acceleration-and-deflection-of-electrons:accel_def_electrons_common_area.png?direct&400|}} | ==== Individual station ==== * CRT (w/ stuck-on ruler) * C-clamp * 24 V power supply * 500 V power supply * 2 Multimeters * 7 banana patch cables (4 black, 3 red) | {{:phylabs:lab_courses:phys-120_130-wiki-home:winter-experiments:electric-fields-ii_acceleration-and-deflection-of-electrons:accel_def_electrons_individual.png?direct&400|}} | ==== Setup notes ==== * Wire-up and check each CRT to ensure it is working correctly. * Adjust beam spot size (using potentiometer knob in the back) if beam spot is distorted or too large. * If necessary, clean the goop off the front of the CRT screen and re-attach cut rulers.
