Last week’s issue of NewsLine announced a wrong date for the “Informal Discussion” to take place in conjunction with the French Linear Collider days. The meeting will take place on Friday, 29 November from 14:00 to 18:00 h at LAL Orsay. A special Indico page has been set up for this event.
Leah Hesla | 4 November 2010Scientists 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.

Leah Hesla | 26 August 2010Achieving resonance in a scientific collaboration is no small feat, but scientists at Fermilab, DESY and KEK have come together to do exactly that: They've improved the mechanism that keeps superconducting radio frequency cavities in tune.Members of Fermilab's Technical Division and DESY staff, with financial assistance from KEK, recently built four new tuning machines that set SRF cavities to the correct frequency and alignment. More highly automated than their predecessors, the machines save time and labor and ensure greater consistency in RF cavity quality. They work by squeezing or stretching individual cells in a nine-cell cavity and allowing all of them to perform identically and impart the same acceleration to the beam.

Leah Hesla | 12 August 2010Last May, in only two weeks' time, a team of Accelerator Division Instrumentation Department employees installed, powered, debugged and started up a brand new, home-made beam position monitoring system at KEK's Accelerator Test Facility. It worked flawlessly.
