Electron Diffraction Notes
The purpose of this lab is to see experimentally how electrons act as waves. This can be done by means of electrons impacting a surface that acts as a diffraction grating. This is an example of the the de Broglie hypothesis that electrons act like waves and particles.
Safety
- Went over Safety with our lab T.A. Pranav Rathi.
- The major concern with this lab is again electrical personnel safety. You don't want to shock your self and get hurt. We are using equipment that has large voltages and currents.
- Equipment safety is also a concern in that the bulb is breakable and you don't want to drop it and watch it shatter. Another concern is when we are connecting the equipment don't run the bias through the heater you may end up frying the bias out due to the fact that it is rated for only 500 mA and the heater is putting out a current of 3A.
Set Up
- I used the following diagram from Darrell Bonn.
Circuit Diagram for the set up of the Electron Diffraction Lab - First I only used 3 different components and bnc cables. I hooked the electron diffraction machine up to the DC power supply. I had to hook up the heater on the power supply (rated at 6.3V 3A) to the F3 and F4 ports, and the high voltage supply(HV Supply) to the G7 and C5 ports with the C5 line also serving as a ground and connected this to a bias to make the whole set up work. I tried to connect the set up with out the bias but it wouldn't work for what reasons I could not tell you.
Equipment
- 3B DC Power Supply (0... 5kV, 6.3V AC/3Amp ,Model U3310)
