Fermilab, SLAC, JLab, Brookhaven, Argonne… these are all major players in particle physics and accelerator R&D. They are also the U.S. Department of Energy’s (DOE’s) “national labs”. All national research labs came to Washington, D.C. on 20 April to show their work to members of Congress and other visitors. Pictured is Dick Durbin, Illinois senator, giving his address. DOE has […]
A conformal approach to cavity coating
Argonne scientists give metals a healthy superconducting coat, one atomic layer at a time.
A necklace of cheap metal with gold-flaked paint may look like solid gold finery, but eventually, the paint will peel, revealing a worthless trinket beneath. But an accelerator cavity of inexpensive metal with a nice niobium coat, though less expensive than a solid niobium structure, could actually hold more value for a particle collider. Scientists […]
A new generation of undulator magnets
Lately, scientific communities are in need of higher-energy light particles. To do this, scientists are extending the existing technology of undulator magnets, or undulators. The device uses magnets to wiggle a particle beam into giving up light, which can then be used for a whole host of scientific applications. “Undulators are specialised beasts,” said Elizabeth […]
You say you want more resolution…
Scientists led by a group at Argonne National Laboratory are bringing pictures of hadronic showers into sharper focus with the Digital Hadron Calorimeter, or DHCAL, one of several hadron calorimeter options for the ILC detector. The Argonne group began testing the device last month at the Fermilab Test Beam Facility. The new particle detector makes […]
