The 2015 Latin-American School of High-Energy Physics will be held in Ibarra, Ecuador from 4 to 17 March 2015. The lectures will cover a broad range of HEP topics at a level suitable for students working for a PhD in experimental particle physics. Note that financial support may be available for Latin-American students attending the School. Although the School is targeted particularly at students from Latin-American countries, it is open to self-funding students coming from other regions.
Details and application deadline can be found here.
Barbara Warmbein | 31 July 2008In a linear accelerator, energy conservation is not really on the achievement list. To get up to the required luminosity, accelerator experts have one chance to push the particle beams to their limits, putting much energy into the bunches, correcting, scraping and tweaking them along the way only to smash them into each other and direct the straggly remains into a dump. Not so an Energy Recovery Linac, currently at the design and first prototype stage at Cornell University. The electron beams also get dumped after one run, but before that happens, they are tricked into handing over their energy back to the superconducting machine that accelerated them.

Barbara Warmbein | 10 July 2008There may not have been a ribbon-cutting ceremony or speeches by heads of state. But the official kick-off of Cornell University's CESR storage ring as ILC damping ring test facility pleased the nearly 40 participants at this week's "Joint CesrTA Kickoff Meeting and ILC Damping Rings R&D Workshop (ILCDR08)" enormously. “CesrTA will give us a detailed picture of the how electron cloud builds up under a range of conditions, of how an ultra-low emittance positron beam interacts with the electron cloud, and of how beam instabilities driven by the electron cloud develop,” says Andy Wolski, damping ring group leader based at the Cockcroft Institute in the UK. “In this respect CesrTA plays a critical role in validating the decision to reduce costs by eliminating the second positron damping ring.”

Barbara Warmbein | 29 May 2008Sometimes even pretty straightforward and remarkably logical ideas take several moves before they become a reality. Take the planned damping rings for the ILC, for example. In the ILC, compact bunches of electrons and positrons are made to collide at very high energy. In order to ensure a high rate of particle collisions, the bunches are cooled in damping rings prior to acceleration. In a cold bunch, the particles are all very close together and travelling in very nearly the same direction with very nearly the same velocity. (In a hot bunch, as in a hot pot of water, the particles are more dispersed and are all moving in different directions.)

22 February 2007In the end of January, the Laboratory for Elementary Particle Physics (LEPP) at Cornell University hosted collaborators from KEK, Lawrence Livermore National Laboratory, Argonne National Laboratory and Alfred University (an undergraduate University in New York State) to conduct electron cloud studies using the CESR storage ring. CESR is unique in that it is a “wiggler dominated” storage ring capable of storing intense beams of both electrons and positrons, singly or simultaneously.
