Modern Physics Laboratory Equipment List

Diffraction

The e over m lab fully set up with the power to the cathode, coils, and accelerating voltage powered on. The image is dark to allow the electron beam's circular path show up.

Equipment List:

  1. Electron Diffraction Set up

    • Electron Diffraction Tube
    • Tube Holder S
    • Kilovolt Power Supply
    • Power Cord
    • Wires:

      • Red Banana Cord (Male to female needed for the older Tube Holders with a male banana plug at G7)
      • 2 x Black Banana Plug (Shrouded Preferred)
      • Blue Banana Plug (Shrouded Preferred)
      • Yellow Banana Plug (Shrouded Preferred)
  2. Light Wave Interference Set up

    • Optics Track
    • Green Diode Laser
    • Green Diode Laser Power Supply
    • Wireless Diffraction Scanner
    • 2 x Wireless Diffraction Scanner Screw
    • USB A to Micro cable (plug this in to the computer and scanner immediately to begin charging)
    • Track Nuts There needs to be at least 2 in the track
  3. Caliper
  4. Bar Magnet

Electron Diffraction Bulb Wiring Guide:

  1. Red Banana Cord: G7 to ( + ) Red High Voltage Terminal
  2. Black Banana Cord: F3 to 6.3V AC Terminal (polarity does not matter)
  3. Black Banana Cord: F4 to 6.3V AC Terminal (polarity does not matter)
  4. Blue Banana Cord: C5 to ( - ) Blue High Voltage Terminal
  5. Yellow Banana Cord: C5 to ( ⏚ ) High Voltage Terminal
    (this cord will be plugged into the back of the blue cord already in C5)

Notes and tests:

The lab set up in a small area with the electron diffraction bulb plugged in and behind the optics track

This is a quick look at what is needed for the lab. It is missing calipers.
