1 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz UC Santa Cruz Tesla Coil Show at Natomas High School

2 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz Santa Cruz Institute for Particle Physics SCIPP n Prof. Hartmut Sadrozinski Your Guests today UC Santa Cruz Department of Physics n Prof. Terry Schalk n Brian Keeney, Junior n Dr. Hiroshi Ohyama n Dr. James Dann ( ex graduate student) n Paul Graham, Instructor, Cabrillo College

3 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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 –Sparks from the feet n Chicken Coop n Who was Nikola Tesla? n Mystery Knight in Armor –Fighting Lightning

4 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz What does a Physicist do? She/he asks Questions about Nature. Today is your chance to be a Physicist: Ask Questions during the Show!

5 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz Professors and Students (and Teachers!) conduct research in the SCIPP Laboratories.

8 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz Summer 2001: Teachers help launch a big Science Balloon Mr. Kliewer Prof. Schalk Dr. Dann Mr. Manildi Mr. Briber

9 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz Balloon Flight, Chase and Recovery Balloon flew 250 Miles across Texas at 130,000 ft, landed with 50g

10 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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!

11 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz ZorroZorro Drawing lightning with a sword

12 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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)

13 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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?

14 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz Learn about Transformers Where have you seen this before? Power comes out at Volts Power goes in at 120 Volts Commercial Transformer, hooked up the “wrong way” Commercial Transformer, hooked up the “wrong way”

15 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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 Volts Power comes out At 120 Volts and a transformer brings it down to 120V

16 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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

17 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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

18 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz Meet the Fighting Knight Fighting Lightning Bolt to the Head Sparks from the feet

19 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz How lightning works – – – – – – – – – – –– – – – –– – – – – – – – – – – – – – – – – –– – – – – – – Ground is safe!

21 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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!

22 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz The “Chicken Coop” The World’s Ugliest Faraday Cage -- and it’s full of holes! But can it keep the lightning out? Does the chicken trust the equations? equations?

23 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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”

24 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz n Nikola Tesla as a Daredevil waiting for a hair cut? n Double Exposure makes it safe!

25 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz Mystery Knight Who is afraid of Lightning? Not the Mystery Knight! Not the Mystery Knight!

26 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz 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

27 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz Fysiks is Phun! Questions? Ask after the show, , visit… You find our coordinates on the web

28 UC Santa Cruz Tesla at Natomas High SCIPP UC Santa Cruz Say “Good bye” to Daniel Greenhouse, the brain behind the sparks He was an undergraduate at UC Santa Cruz. at UC Santa Cruz. Thanks to our hosts: n All you students n Mr. Hageman n Ms. Connely n Mr. Dann n Ms. Frazier
