Outline • What is antimatter? • Energy created by antimatter matter collisions • History • Production • Storage • Current and Theoretical Uses • Antiuniverse Theory
What is antimatter? • Antimatter is the counter part to matter • For every element there is an antielement • All antielements are the same mass with opposite charges, and magnetic moment
What is antimatter? • Matter cannot be created without antimatter. • Where is all the antimatter?
Energy • E = mc^2 • m/2 of antimatter and m/2 of matter, 100% energy yield
Energy BOOM proton antiproton electron p positron _ p H _ H γ γ hydrogen antihydrogen
History • Paul Dirac • Carl Anderson • Emilio Segre and Owen Chamberlain
Paul Dirac The history of antimatter begins in 1928 with the physicist Paul Dirac
Carl David Anderson In 1932 the next logical step in the history of antimatter was taken. The prediction turned reality
Emilio Segre&Owen Chamberlain In 1955 using the Bevatron accelerator at Berkley University, antiprotons were artificially produced
Artificial Production • Artificially producing antimatter is an extremely inefficient process • High energy collisions are required • Penning traps capture the antiprotons
Idiot’s guide to making antihydrogen • Accelerate a proton to high velocities • Smash it into something (Tungsten) • Catch in penning trap • Throw Positrons at it • To observe • Decelerate the antiproton • Throw electrons at it • Take the electrons away • Throw Positrons at it
Top Research Facilities CERN Geneva, Switzerland Fermilab Chicago, USA
CERN • The largest particle physics facility in the world • Created antihydrogen in 1995 • Activated the Antiproton Decelerator in 1999 Antiproton Collector and Antiproton Accumilator
Fermilab • Proposed site for the International Linear Collider • Creates antiprotons on a regular basis with the Tevatron Collider the Tevatron Collider
Natural Production • High energy cosmic ray matter collisions • Radioactive decay (positive beta decay)
Storage • Storage is difficult because shortly after creation antimatter particles contact matter particles and annihilate. • We can only produce an extremely small amount of antimatter “If we could assemble all of the antimatter we've ever made at CERN and annihilate it with matter, we would have enough energy to light a single electric light bulb for a few minutes”
Current and Theoretical Uses • PET Scans (Positron Emission Tomography) • Study particle behavior • Weapons • Fuel Energy
Antiuniverse Theory • Dirac was first to contemplate it’s existence • Antiuniverse would exist of antistars antigalaxys antiplanets and antiyou • Boundry between them would create a lot of gamma rays
