PHYS 3446 Lecture 15 Monday Oct 30 2006 Dr Jae Yu 1 Particle Accelerators Electro static Accelerators Cyclotron Accelerators Synchrotron Accelerators 2 Elementary Particle Properties Monday Oct 30 2006 Forces and their relative magnitudes Elementary particles Quantum Numbers Gell Mann Nishijima Relations Production and Decay of Resonances PHYS 3446 Fall 2006 Jae Yu 1 Announcements Quiz in class Wednesday Nov 1 LPCC Workshop Saturday Nov 4 Homework Carry out Fourier transformation and derive equations 9 3 and 9 5 Monday Oct 30 2006 PHYS 3446 Fall 2006 Jae Yu 2 Particle Accelerators How can one obtain high energy particles Cosmic ray Sometimes we observe 1000TeV cosmic rays Insufficient statistics due to low flux Cannot control momenta too well Need to look into small distances to probe the fundamental constituents with full control of particle energies and fluxes Particle accelerators What else do you think accelerators have do other than particle acceleration Track them Maneuver focus or turn them Constrain their motions to the order of 1 m Why Must correct particle paths and momenta to increase fluxes and control momenta Monday Oct 30 2006 PHYS 3446 Fall 2006 Jae Yu 3 Particle Accelerator Types Depending on what the main goals of physics are one needs different kinds of accelerator experiments Fixed target experiments Probe the nature of the nucleons Structure functions Use neutrinos or charged leptons electrons or muons to probe proton or neutron internal structure Results also can be used for producing secondary particles for further accelerations Tevatron anti proton production Colliders Probes the interactions between fundamental constituents Hadron colliders Wide kinematic ranges and high discovery potential Proton anti proton TeVatron at Fermilab Sp pS at CERN Proton Proton Large Hadron Collider at CERN late 2007 Monday Oct 30 2006 PHYS 3446 Fall 2006 Jae Yu 4 Particle Accelerator Types Lepton colliders Very narrow kinematic reach so it is used for precision
