Slide 2 Placemat Weve talked about particles, charged particles...so what could we learn about Particle accelerators? Slide 3 You have 3 minutes to write down as much as you can. What could we learn about particle accelerators? What do you want to know? Slide 4 You will now take it in turns to discuss your thoughts. Your goal is to agree on the two questions you think it is most important to explore in this section. You must all be able to explain the groups reasoning. Discuss, explaining your reasoning Once you have reached agreement, write the two questions in the centre Slide 5 As we progress through the unit, note down questions that you would ask a particle physicist if you met one.

Slide 8 But lets get a handle on that number. The cost is shared by the 20 member states of Conseil Europen pour la Recherche Nuclaire (CERN). The UKs direct contribution to the LHC is 34 million per year (thats 55p per person in the UK). Slide 9 The UK pays 70 milliom per year as an annual subscription to CERN. Slide 10 Compare that with 431 million Slide 11 Compare that with 850 billion Slide 12 Compare that with 692 million Slide 13 Compare that with 95.6 million Slide 14 Compare that with 365 million Slide 15 Still not convinced? Slide 16 What is this story? One is the will to show that after the devastation caused by the worlds first atomic bomb in 1945, physics research could be used to do something for peace. It is a story, in the planning and throughout its 56- year history, of pushing technology and human ingenuity to the limits. Slide 17 What is this story? A story of the power of science to overcome physical, political and religious boundaries. Slide 18 What is this story? A story of that tells us that science is alive. And it matters. And that all that is needed for creative thinking is freedom. Slide 19 At the moment of impact of the particles, a previously unachievable temperature is reached. Protons (hadrons) are approaching the speed of light. Particles are released that have not existed in a free state since the Big Bang. Slide 20 Of all of the information generated, anywhere in the world, in any format, 1% of it comes from the LHC. In 2004, this required 30,00040,000 of the high spec PCs at CERN itself, plus 1012 major centres around the world and 5060 smaller centres. Now you perhaps understand why they needed to invent the world wide web! Slide 21 The simplest type of particle accelerator forms the basis of traditional CRT television and computer monitor technology. The cathode-ray tube we have used in the lab is a particle accelerator. On a much smaller scale than CERN of course! Slide 22 A particle accelerator is designed 'to speed up and increase the energy of a beam of particles by generating electric fields that accelerate the particles, and magnetic fields that steer and focus them.' 'Accelerators were invented to provide energetic particles to investigate the structure of the atomic nucleus.'

You must submit a bid (in electronic form) that is thoroughly researched, investigated and costed. Image courtesy of CERN Slide 26 an electronic presentation, fully referenced. Consider the use of images and multimedia (eg video files) to support your case. Image courtesy of CERN Slide 27 Include a scientific explanation, with clear diagrams, of the operation of your accelerator. Include details of each of the basic parts of an accelerator and what it does. Explain the physics! Image courtesy of CERN Slide 28 Include a case for support, including the purpose and benefits of the particle accelerator, and historical information. eg a similar accelerator which cost x in 19xx operated successfully for 25 years. Image courtesy of CERN Slide 29 Quality information, referenced and cros- referenced. Scientific explanations of the operation of particle accelerators. Numbers! Lengths, strengths and comparisons to allow us to get a handle on the numbers. Understanding the basics of the operation of particle accelerators. Slide 30 Group A: A synchrotron for medical applications Group B: A cyclotron for cancer treatment (proton therapy) and PET imaging Group C: A linear accelerator (LINAC) Group D: A cyclotron for nuclear physics research Group E: A synchrotron for life science and materials research applications Slide 31 CERN is a high-quality, cutting-edge source of information. The website includes simulations, videos and lots of other resources The UKs Diamond Light Source particle accelerator http://insidediamond.org also has high-quality information on its general website and in the education section. http://insidediamond.org Stanford University (home of the SLAC) has a virtual visitor centre http://www2.slac.stanford.edu/vvc/ http://www2.slac.stanford.edu/vvc/ Fermilab anatomy of a detector and much more! (fermilab) Slide 32 Are there questions to which you just cannot find the answer? Would you like some help from a particle physicist? Write your questions in your jotter.
