Compact, CRT-Based Electron Properties Lab
Study Electrostatic & Magnetic Deflection and Measure e/m
Precision Multi-Turn Potentiometer Controls and Digital Meters for Quantitative Studies
This electron properties lab is based on a 75mm flat screen CRT, and is contained in a compact metal case with a removable lid. All the accessories needed to explore electrostatic deflection, focusing, and electron behavior in transverse and axial magnetic fields are included. The power supply and measurement circuitry is entirely enclosed for safety and reliability. Multi-turn potentiometers and three 3-1/2 –digit LED meter displays help students easily obtain precise results. A full operator’s manual with experiment descriptions is included, and explains both background and procedures, including the determination of e/m using the focusing effect of an electron beam spiraling around an axial magnetic field.
