Mass of Electron apparatus kit, w/ tube, w/out solenoid

Mass of Electron apparatus is a 'Magic Eye' tube mounted on a base with terminals to accept both heater and plate voltages. A fan of electrons can be seen by viewing through the end of the tube. An Air Cored Solenoid is placed over the tube and a current passed through the solenoid. The field at the centre of the solenoid causes the fan to curve (distort) and this curvature is measured to permit the approximate mass of an electron to be calculated.
