1 Welcome RAL Particle Physics Masterclasses March 2003 Glenn Patrick

2 100 Years -Thomson to Higgs Geiger, Marsden and Rutherford discovered the nucleus using  particles (University of Manchester) Investigating quark structure of matter and hunting the Higgs Boson. Building the Large Hadron Collider -27km circumference! 1897 J.J. Thomson discovered the electron using a cathode ray tube. (Cavendish Laboratory)

3 Particle Physics and RAL Rutherford High Energy Laboratory created in 1957 for research into particle physics. UK accelerators - NIMROD proton synchrotron  Closed in 1978 and revamped as ISIS pulsed neutron source - visit today. Today, RAL is a multi-disciplinary laboratory employing about 1200 people with  90 people in the Particle Physics Department. Mainly using international facilities - CERN (Geneva), DESY (Hamburg), SLAC (Stanford), FNAL (Chicago) + underground expts in Minnesota, Sudbury, Boulby…  Talks today will cover some of the work in these centres + future projects.

4 ISIS - Pulsed Neutron Source Protons from 800 MeV synchrotron bombard a metal target to produce neutrons (plus muons & neutrinos). World’s brightest pulsed neutron source. Condensed matter physics, disordered materials, biological materials, structural chemistry, etc + particle physics expts. KARMEN ( ), MICE(  )

5 SLAC, Stanford DESY, HamburgCERN, Geneva FermiLab, Chicago

6 DIAMOND Synchrotron To be built at RAL. Start of operation = Cost = £235M. Studies at molecular/atomic level. Ground-breaking - Wednesday 12th March!  ee

7 Laser Physics Vulcan - High power neodymium (Nd) glass laser. Peak power of 1 Petawatt (10 15 Watts) Plasma physics, new acceleration techniques, astrophysics simulations, etc. Interaction Chamber Compression Grating 500J in 500fs pulse

8 Space Science Planck, Herschel Space Observatory, Mars Express/Beagle, Cassini, Cluster II, SOHO,IRAS, + many more. Many projects/missions using both satellites and ground-based telescopes. Vaccum/vibration testing facilities.

9 Cosmic Microwave Background (2.7°K) from COBE Satellite Amplitude of temperature fluctuations is K or 30+/-3  K in 10 degree patches. (1 part in 100,000) Extremely Isotropic. Anisotropy is only 1 part in 10,000 Believed to have resulted from quantum fluctuations of the universe when it was the size of a grapefruit! Extremely Isotropic. Anisotropy is only 1 part in 10,000 Believed to have resulted from quantum fluctuations of the universe when it was the size of a grapefruit! Next generation - WMAP(2001), Planck(2007)

10 Studying Big Bang Conditions E  kT E = mc 2

11 Advanced Grid Computing ATLAS at LHC: 40MHz interaction rate  1PB+ data/year (1.4 million CDs!)
