Obtaining Particles to Accelerate



Electrons: Heating metal causes electrons to be ejected
Television tubes uses this mechanism.


Protons: Easily be obtained by ionizing hydrogen
discharge a spark in it



Want to study massive, unstable particles that have only a fleeting existence? 
All that we have in the every day world are very low-mass particles.

Use particles with lesser mass, but bigger energy to obtain particles of greater mass

Albert Einstein's famous equation: E=mc,  where E is the energy, m is the mass, and c is the speed of ligh



Antiparticles: First have very energetic particles hit a target
Then pairs of particles and antiparticles will be createdfrom energy. Magnetic fields can be used to separate oppositely charged particles and anti-particles
