1 Stern-Gerlach Experiment Physics 243 Fall 2007 Chris Osborn Daniel Richman

2 Status Report Components of the experiment Gradus ad parnassum Current stage Degas?

3 Components detector – reads current from ions from potassium oven

4 Components handle for detection rotation

5 Components electromagnet driving coils

6 Components mechanical pump

7 Components diffusion pump water cooling pipes

8 Components potassium oven

9 Components pressure gauge via ionization

10 Components ionization gauge pressure gauge thermocouple gauge electrometer magnet power supply

11 Gradus ad parnassum Evacuate chamber –mechanical to 10 -2 mbar –diffusion to 4x10 -5 mbar (with cooling) Potassium oven –load potassium under nitrogen pressure –heat to 180 o C – 250 o C Detect beam of particles –Do we have a collimated/directed beam? –Why aren’t we seeing a current on electrometer? no consistent behavior of electrometer

12 degas button?

13 Edgar Degas (1834 – 1917) Draughtsman, Painter, Sculptor A founder of the Impressionists, though he rejected the label
