Electron DiffractionPurpose1) To demonstrate the wave properties of electrons. Theorythe wavelength of a proton traveling at .5c is on the order of 10^-3 pm! the diameter of an atom is around 60 to 600 pm! Equipment
Safety
ProcedureThe procedure should be followed from the Lab Manual experiment 3, electron diffraction. The following circuit was set up, with the following modification: The low voltage bias was inverted; a multimeter was put in series between the positive HV source and plug G7 on the mount to measure current. NOTE: the max voltage measurable by the multimeter is 1000V. It is important to only measure current with the multimeter while it is connected to prevent damage to the instrument as up to 5kV will be used in this experiment. Raw DataThe rings were very difficult to discern while centered, but with a slight offset, they became easier to measure. The offset will be recorded for each voltage.
