1 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. UC Santa Cruz Tesla Coil Show at Tierra Linda M.S., San Carlos

2 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Santa Cruz Institute for Particle Physics SCIPP n Prof. Hartmut Sadrozinski Stanford Linear Accelerator Center Your Guests today n Dr. Charlie Crummer, UCSC Laboratory Manager n Dr. Norman Graf n Dr. Tom Glanzman n Ms. Amy Wells, graduate student

3 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Tesla Program n Introduction & Jacob's Ladder n Safety First n Corona: –Zorro’s Sword –Lights without Cords n How the Tesla Coil Works n Knight in Armor –Bolt to the face –Fighting Lightning n Who was Nikola Tesla? n Mystery Knight in Armor –Sparks from the feet

4 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. What does a Physicist do? She/he asks Questions about Nature. Today is your chance to be a Physicist: Ask Questions during/after the Show!

5 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Teach students, learn about nature (Research) Smallest objects (Particles): Quarks How do objects form and stay together? Big objects in the sky: Stars, Black holes, Supernovae

6 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Galaxy DNA Cell Atom Nucleus Electron microscope Accelerator The size of the object and its distance tells me what kind of instrument I need to see it. Larger & Farther away Smaller & Harder to see From Biggest To Smallest...

7 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Professors and Students (and Teachers! And H.S. students) conduct research in the UCSC and SLAC Laboratories. http://scipp.ucsc.eduhttp://www.slac.stanford.edu

8 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. COSMOS: UCSC Summer Program for H.S. students. Soon you can go! http://epc.ucsc.edu/cosmos

9 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. n Normally you can't see, hear or smell electricity, but the Tesla Coil makes Bright sparks Bright sparks Loud crackling noise Loud crackling noise The air smell strange (Ozone) The air smell strange (Ozone) SAFETY FIRST! BRACE YOURSELF! 1 Million Volts! DANGER n Distance at least 20 ft. n Computers, Gameboys, CD players, telephones to the back of the room – unplugged, switched off! n Hearing aids off, pacemakers out of room!

10 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. ZorroZorro Drawing lightning with a sword

11 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Sparks to grounded sword What is happening with Zorro? Wire to safe ground What about those lights without cords? Electricity Moves Through the Air (you knew that, because you use a radio and TV)

12 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Voltage starts at 120 ends up at 1 million! Transformer 14,000 volt Outlet 120 volt Resonance circuit 1 million volt Ask us about details! How does the Tesla Coil work?

13 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Learn about Transformers Where have you seen this before? Power comes out at 14000 Volts Power goes in at 120 Volts Commercial Transformer, hooked up the “wrong way” Commercial Transformer, hooked up the “wrong way”

14 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. We hear a lot about conserving Power (turn off lamps, air conditioners, close refrigerator doors...) Electrical Power is just converted wind, water, thermal power It is brought to your neighborhood on high voltage lines We hear a lot about conserving Power (turn off lamps, air conditioners, close refrigerator doors...) Electrical Power is just converted wind, water, thermal power It is brought to your neighborhood on high voltage lines Physics Principle: Transformer Power goes in at 14000 Volts Power comes out At 120 Volts and a transformer brings it down to 120V

15 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Transformation of Power GLAST SLAC n Power is used everywhere –Visit the Stanford Linear Accelerator Center (SLAC): Electricity -> New particles Quarks Power is tranformed in Space Power is tranformed in Space Black holes explode : Black holes explode : – Material -> Light, x-rays, “jets” – SCIPP works on GLAST Mission: discover the most powerful “power plants” in the universe discover the most powerful “power plants” in the universe

16 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Learn about Resonance That’s how a swing works: A kick at the right moment builds up and gets you sky-high! That’s how a swing works: A kick at the right moment builds up and gets you sky-high! In the Tesla “swing”, the kick is supplied by the AC electrical current moving back and forth In the Tesla “swing”, the kick is supplied by the AC electrical current moving back and forth

17 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Meet the Fighting Knight Fighting Lightning Bolt to the Head

18 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Principle:Air is made of very small bodies called “molecules”. When they are broken apart, they become charged and can conduct a current like an electrical wire. If there is a large current, it heats up the air and makes light (like in your toaster!). Electricity in Air

20 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. The Faraday Cage Planes are close to the clouds and away from safe ground. Why aren’t they in grave danger from lightning? ++ + + + + +++ ++ + –– – – – – – –– – – – – + +++ + + + Safest place during a lightning storm is in a plane or car because it is a Faraday Cage Answer: They form a “Faraday Cage” -- that is, they are surrounded by metal. Electricity flows around the outside of the metal, and anything inside is safe!

21 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Thomas “DC” Edison Thomas “DC” Edison and his Batteries Nikola “AC” Tesla and his Generators vs. n Tesla Revival n 271 web sites are dedicated to Nikola Tesla n Join the “Tesla Coil Web Ring” http://nav.webring.yahoo.com/hub?ring=teslaring&list

22 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. n Niagara Falls Power Station

23 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. n Nikola Tesla as a Daredevil waiting for a hair cut? n Double Exposure makes it safe!

24 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Mystery Knight Who is afraid of Lightning? Not the Mystery Knight! Not the Mystery Knight!

25 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Electrical current flows on the OUTSIDE of a metal! Is the Mystery Knight OK?Let’s check! The armored suit is safe! n It's a Faraday Cage – no electric field allowed inside. Is the Mystery Knight OK?Let’s check! The armored suit is safe! n It's a Faraday Cage – no electric field allowed inside. Invisible current Visible sparks Ground 1 Million Volts Visible sparks

26 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Fysiks is Phun! Questions? Ask after the show, e-mail, visit… You find our coordinates on the web http://scipp.ucsc.edu

27 SCIPP UC Santa Cruz UC Santa Cruz Tesla @ Tierra Linda M.S. Say “Good bye” to Daniel Greenhouse, the brain behind the sparks He was an undergraduate at UC Santa Cruz. at UC Santa Cruz. http://scipp.ucsc.edu Thanks to our hosts: n All you students n Ms. A. Haselton n The Mystery Knight
