ACCELERATORS: - THE TV TUBE IS AN ACCELERATOR BECAUSE.... | IT ACCELERATES ELECTRONS THROUGH PD OF ABOUT 500V. |
THE ELECTRONS FROM A BEAM, WHICH HIT THE INSIDE OF TV SCREEN. MAGNETIC FIELDS PRODUCED BY ELECTROMAGNETS DEFLECT THE BEAMS SO IT CAN SCAN THE SCREEN TO CREATE IMAGE. | |
THE LONGEST ACCELERATOR IN THE WORLD IN... | THE STANFORD LINEAR ACCELERATOR IN CALIFORNIA. |
THE BIGGEST ACCELERATOR IN THE WORLD IS ... | THE LARGE HADRON COLLIDER AT CERN GENEVA – |
LHC IS DESIGNED TO ACCELERATE.... | CHARGE PARTICLES TO ENERGIES MORE THAN 7000GEV. 27KM CIRCUMFERENCE RING CONSTRUCTED IN CIRCULAR TUNNEL BELOW THE GROUND. |
PROTONS , NEUTRONS , PI MESONS AND K MESONS ARE ALL EXAMPLES OF... | PARTICLES WE CALL HADRONS BECAUSE THEY EXPERIENCE A STRONG INTERACTION . |
HADRONS PARTICLES EXPERIENCE... | A STRONG NUCLEAR INTERACTION |
NUETRION WHICH IS ONE TYPE OF HADRON ... | BECAUSE EXPERINCES STRONG NUECLEAR FORCE, DOESN;T DECAYS INTO OTHER PARTICLES. |
CHARGE PI PARTICLES PRODUCED IN PAIRS LEADING TO CONCLUSION THAT... | PI POS MESONS AND PI NEG MESONS ARE A PARTICLE ANTIPARTICLE PAIR. THE SAME CONCLUSION FOR K MESONS. |
THE SYMBOLS FOR THE ANTIPROTON ANTINEUTRON AND ANTINEUTRINO IS... | THE SYMBOL WITH A BAR ON TOP APART FROM THE ANTIMUON AND POSITRON. |
WE CAN DIVIDE THEM INTO 2 GROUPS CALLED... | HADRONS AND LEPTONS. |
THE 2 HADRON LEPTONS GRPS ARE ACCORDING TO... | WHETHER OR NOT THEY INTERACTION THROUGH THE STRONG INTERACTION. |
HADRONS ARE ... | PARTICLES AND ANTIPARTICLES – THAT CAN INTERACT THROUGH STRONG INTERACTION |
EXAMPLES OF HADRONS INTERACTION THROUGH STRONG INTERACTION ... | (E.G. POSITRONS , NEUTRONS , PI MESONS AND K MESON. |
LEPTONS ARE.... | PARTICLES AND ANTIPARTICLE THAT DO NOT INTERACT THROUGH THE STRONG INTERACTION. |
EXAMPLES OF LEPTON THAT DECAYS THROUGH WEAK INTERACTION ... | ELECTRON , MUON AND NEUTRINOS. |
LEPTONS INTERACT THROUGH ... | THE WEAK INTERACTION AND THROUGH THE EM INTERACTIONS IF CHARGED. |
WHTA ELSE CAN LEPTON INTERACT IN ... | EM INTERCATION IF CHARGED.SAME FOR HADRONS |
WEIGT OF LEPTONS... | LIGHT AND WEAK , |
HAWEIGHT OF HADRONS... | STRONG AND HEAVY. |
FIXED MAGNETS ALL THE WAY ROUND THE RING IN THE LHC BEND... | THE PATH OF THE PARTICLES TO KEEP THEM IN THE RING. |
WHEN PARTICLES COLLIDE IN LHC THE TOTAL ENERGY... | OF THE PARTICLES AND ANTIPARTICLES BEFORE THE COLLISION= THE REST ENERGY + THE KINETIC ENERGY. |
THE TOTAL ENERGY OF THE NEW PARTICLE AND ANTIPARTICLES AFTER THE COLLISION =... | THEIR REST ENERGY + THE KINETIC ENERGY. |
THE REST ENERGY OF PRODUCTS =. | . TOTAL ENERGY BEFORE - THE TOTAL ENERGY OF THE PRODUCTS. E.G. IS AN PROTON AND A ANTI PROTON COLLIDE WITH KINETIC ENERGY 2GEV . 1GEV= 1000MEV. |
K MESON ARE CREATED WHAT PRODUCED .... | SHORT LIVED PARTICLES WITH GREATER REST MASSES THAN PROTON PRODUCED. PARTICLE CREATED THROUGH STRONG INTERACTION SO THEY ARE HADRONS. THEY DECAY INTO PROTONS AND PI MESON. |
WHEREAS PROTONS ARE NEVER AMONG THE DECAY PRODUCTS OF... | K MESONS |
