● Self-protective, highly stable power supply for accelerating, grid plates and focusing.
● 24V safe voltage inside the machine, electric shock prevented.
● use 5 digital display meters , no need to switch between readings.
● both manual and auto scanning for focusing, easy to observe results.
● Affordable
This LEEI-20 experiment apparatus is designed for the quantitative investigations of electron beam properties in electric and magnetic fields, experiment contents include the deflection in a transverse electric field, focusing in an inhomogeneous longitudinal electric field, deflection in a transverse magnetic field, and spiral motion about a longitudinal magnetic field, as well as the determination of the Specific Change of the Electron (or the electron charge/mass ratio (e/m)). It is an ideal teaching apparatus for physics laboratories in colleges and universities.
