SCIPPs Research extends from the smallest
particles to the largest structures in the
Universe

Graduate and Undergraduate Students conduct
research in the SCIPP Laboratories
and have fun visiting SLAC

• Safety First
• Corona
• Zorros Sword
• Lights without Cords
• Facts on Lightning
• Facts on Tesla Coil
• Mystery Knight in Armor
• Fighting Lightning
• Bolt to the face
• Sparks from the feet
• Any Questions ?

7
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

Lightning Jacobs Ladder Corona
Tesla Sparks are all related.
Principle Air becomes ionized, and therefore
conducts electricity. Lots of it, so the
current heats up the air, excites the
atoms/molecules which emit light.
10
The Power of the Electro- Magnetic
Field !
What about those lights without cords?
What is happening with Zorro?
11
Two important concepts

• Lightning
• The Faraday Cage

12
How lightning works
13
The Faraday Cage
Why aren't air planes in grave danger being so
close to the clouds and all?
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
14
Thomas DC Edison
vs.
Nicola AC Tesla

• Tesla Revival
• 271 web sites are dedicated to Nicola Tesla
• Join the Tesla Coil Web Ring

15
Principle of the Tesla Coil
Ask your teachers about details!
Voltage starts at 120 ends up at 1 million!
16

• Nicola Tesla as a Daredevil?

• Double Exposure makes it safe!

17
Physics Principle Transformer
Power out Power in Power Volt ? Current
Power out _at_14kV
Where have you seen this before?
Power in _at_120V
18

• Transformation of Energy

• Similar to the Tesla Coil, accelerators convert
  energy into new forms
• Visit the Stanford Linear Accelerator Center
  (SLAC) Electricity -gt New particles
• SCIPP works on BaBar
• why we are made out of matter

• In Space in black holes
• Matter -gt Light, x-rays, jets
• SCIPP works on GLAST Mission
• discover the most powerful
  accelerators in the universe

19
Physics Principle Resonance
A kick at the right frequency builds up and gets
you sky-high!
20
Mystery Knight
Fighting Lightning Bolt to the Head Sparks from
the feet
21

• Is Teela ok? Lets check!
• The armored suit is safe!
• It's a Faraday Cage no electric field allowed
  inside

Invisible current
1 Million Volt
Electrical current flows on the OUTSIDE of a
metal!

• Thanks to our hosts
• All you students
• Anne MacLachlan

Say Good bye to Daniel Greenhouse, the brain
behind the sparks He is an undergraduate at UC
Santa Cruz.
