  1. UC Santa Cruz Tesla at St. Ignatius College Prep

  2. UC Santa Cruz Tesla at St. Ignatius College Prep Your guests are from the University of California Santa Cruz (UCSC): Santa Cruz Institute for Particle Physics (SCIPP) • Professor Hartmut Sadrozinski • Professor Terry Schalk Department of Physics • Dr. Charlie Crummer, Lab Manager • Colleen Milbury, student

  3. UC Santa Cruz Tesla at St. Ignatius College Prep Program • Jacob's Ladder • Corona • Zorro’s Revenge • Intro on lightning • Knight in Armor • Intro on Tesla Coil • Lighting to the face • Lights with no wires • Jumping Jacks Thanks to our hosts • James Dann (Physics Teacher) • Father Tony Sauer (President) • Charlie Dullea (Principal) • Kate Kodros (Vice Principal)

  4. 1 Million Volts! DANGER • Normally you can't see, hear or smell electricity, but the Tesla Coil makes • Bright sparks • Loud crackling noise • The air smell bad (Ozone BRACE YOURSELF! UC Santa Cruz Tesla at St. Ignatius College Prep SAFETY FIRST! • Distance at least 20 ft. • Computers, Gameboys, CD players, telephones to the back of the room – unplugged, switched off! • Hearing aids off, pacemakers out of room

  5. Zorro

  6. UC Santa Cruz Tesla at St. Ignatius College Prep At the beginning of the show there are two concepts we must understand • Lightning • The Faraday Cage

  8. UC Santa Cruz Tesla at St. Ignatius College Prep Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Principle: Air becomes ionized, and therefore conducts electricity. Lot’s of it, so the current heats up the air, excites the atoms/molecules which emit light.

Answer: They form a Faraday Cage i.e., they are surrounded by metal; if you are surrounded by metal you are safe the electricity flows around the outside

  10. Mystery Knight

  11. UC Santa Cruz Tesla at St. Ignatius College Prep • Why does Thomas (“Mr. Electricity”) Edison look so grim? • Is it because he preferred DC current?

  12. UC Santa Cruz Tesla at St. Ignatius College Prep • Why does Mr. Nicola (“Sparky”) Tesla look so dapper? • Is it because he preferred AC current?

  13. UC Santa Cruz Tesla at St. Ignatius College Prep • Tesla’s Power Plant at Niagara

  14. UC Santa Cruz Tesla at St. Ignatius College Prep • Nicola Tesla as a Daredevil? • Long Time Exposure makes it safe!

  15. UC Santa Cruz Tesla at St. Ignatius College Prep

  16. UC Santa Cruz Tesla at St. Ignatius College Prep • Let’s get to know the Tesla Coil

  17. 120 volt Outlet 14,000 volt Transformer 1 million volt Resonance circuit UC Santa Cruz Tesla at St. Ignatius College Prep Principle of the Tesla Coil Ask your teachers about details! Voltage starts at 120 ends up at 1 million!

  18. UC Santa Cruz Tesla at St. Ignatius College Prep Transformer Power out = Power in Power = Volt  Current Power out Where have you seen this before? Power in Later on in class you will see a Transformer demonstration.

  19. Invisible current Visible sparks UC Santa Cruz Tesla at St. Ignatius College Prep The armored suit is safe! • It's a Faraday Cage – no electric field allowed inside Electrical current flows on the OUTSIDE of a metal! Ground In a thunderstorm stay in the car!

  20. Amplitude = Force M (f2natural – f2force) UC Santa Cruz Tesla at St. Ignatius College Prep Resonance circuit A kick at the right frequency build up and gets you sky-high!

  21. Lightning Boxing

  22. UC Santa Cruz Tesla at St. Ignatius College Prep UCSC • Teaching • Research • Outreach

  23. UC Santa Cruz Tesla at St. Ignatius College Prep • 10 Residential Colleges

  24. Particle Astrophysics & Cosmology • Teaching, Research, Outreach • Condensed Matter Physics & Wave Propagation • Elementary Particle Physics UC Santa Cruz Tesla at St. Ignatius College Prep

  25. UC Santa Cruz Tesla at St. Ignatius College Prep • Student Research

  26. SLAC • Similar to the Tesla Coil, accelerators convert Energy into new forms • Visit the Standford Linear Accelerator Center (SLAC): Electricity  New particles • SCIPP works on BaBar : why we are made out of matter GLAST • In Space in black holes: • Matter  Light, x-rays, “jets” • SCIPP works on GLAST Mission: • investigate the most powerful accelerators in the universe UC Santa Cruz Tesla at St. Ignatius College Prep Transformation of Energy

  27. Galaxy DNA Cell Atom Nucleus Electron microscope Accelerator UC Santa Cruz Tesla at St. Ignatius College Prep The world is full of mysteries, from the tiny to the gigantic There is plenty to learn and discover!
