Presentation Transcript

  1. Group 2 Bubble Chamber Workshop

  2. Who is this presentation for? • Students in grade 12 or 1st year university (depends on the country and the program) • Prerequisite knowledge: • Electric and magnetic fields • Conservation of charge • Conservation of linear momentum in 2D • Lorentz force, trajectory of charged particles in perpendicular magnetic fields (i.e. hand rule!)

  3. Resources

  4. Activity • What do you see?

  5. Mini-lesson • Which way are the smallest, spiraling tracks going within an individual photo? These are all made by electrons.

  6. Activity • What are the other tracks doing? What are their charges? What is the charge of the incoming beam?

  7. Mini-lesson • A bubble chamber is filled with liquid hydrogen gas. • The particles that make up the incoming beam collide with the protons in the hydrogen gas. Protons are always the target. • How do we apply conservation of charge to these interactions?

  8. Activity: Applying cons. of charge • Go back to your photographs….does using conservation of charge predict the same charges as you got previously from using the radius?

  9. Mini-lesson • Radius can be used to determine the momentum of the particle that made a track

  10. Activity • Measure the radius of each track. • Use the radius to determine the momentum of the particle that made each track.

  11. Mini-lesson • How do we analyze the momentum of linear collisions in 2D?

  12. Activity • Set x and y axis on your photograph. Using a protractor to measure angles, measure the total momentum in the x and in the y before and after the collision.

  13. Mini-lesson • Why was momentum not conserved in some of the photographs? • Interaction might not be in the plane of the photograph • A neutral particle may have carried some of the “missing” momentum

  14. Links to the LHC
