The world’s first horizontal multi-beam klystron has started its site acceptance test at DESY. Built by the Japanese company Toshiba, it is the first of three prototypes from different companies to arrive for the test that will determine whether the new klystron design works. The 10-megawatt horizontal klystron was developed for the European X-ray Free […]
Telescope arms open wide
The EUDET telescope, a high-precision device that lets detector developers check the accuracy of their prototype by using particle beams and the EUDET telescope and comparing with accurately its determined tracks, has just finished a marathon in test beams around Europe. During six weeks in beams at DESY and CERN its makers tested it to […]
Piece by piece
Fermilab and DESY collaborate to build the first U.S. cryomodule
The 1200 parts started to arrive at Fermilab in June. When fully assembled, these many parts will make up the first cryomodule for International Linear Collider R&D in the United States. The ILC will ultimately require 1680 of these cooled modules that hold the superconducting cavities, maintaining a temperature only two degrees above absolute zero. […]
Live from the test beam: calorimetry rises from the ashes
This summer, a stage was all the world for some of the men and women of the CALICE collaboration. For the first time, the full prototypes of the electromagnetic calorimeter, the hadronic calorimeter and the tailcatcher and muon tracker (designed and built by international collaborations and assembled in Paris, Hamburg and Northern Illinois respectively) played […]
Mapping a magnet
Three pairs of eyes cast one last look around the room. Have all scissors, ladders, metallic tables been removed? No pins or pens lying around anymore? Once the team is sure that nothing is left in the area, they close the security doors and give the go-ahead – the magnet that has been to space […]
ILC Project Tools: Implementing the ILC EDMS
Director’s Corner 5 July 2007 Barry Barish ILC Project Tools: Implementing ILC EDMS In September 2005, soon after the GDE was formed, I announced the formation of a special committee to help us select a suite of project tools for the GDE. That committee consisted of Tom Markiewicz (SLAC), John Ferguson (CERN), Lars Hagge (DESY), […]
LCWS 2007 & ILC 2007
Director’s Corner 7 June 2007 Brian Foster LCWS 2007 & ILC 2007 Today’s issue features a Director’s Corner from Brian Foster, GDE European Regional Director. Hamburg put on its best face to greet the more than 600 registered guests who arrived at DESY last week for the big annual ILC get-together; blue skies and sunny […]
Living the Standard Model and Beyond: DESY Theorist Peter Zerwas retires
In a packed auditorium many of world’s leading high-energy physics brains celebrated ‘one of the sculptors of the physics of the ILC which wouldn’t be doable without him’, said Rolf-Dieter Heuer, DESY, and ‘not just a colleague, more of a friend’, said Siegfried Bethke, Max Planck Institute for Physics. Last Tuesday, a day before the […]
How a calorimeter could save your life
Not many people see an immediate connection between exploring the origins of the Universe and finding cancer cells. Nicola d’Ascenzo and his colleagues sure do. In their work to test photo sensors as potential candidates for an ILC hadronic calorimeter they have come across a sensor that could be extremely interesting for positron emission tomography […]
Test Beam Encounters: ECal meets HCal
Team in the beam: Asian ECal makes measurements in the test beam at DESY Layers of the electromagnetic calorimeter in the test beam When scientists take their detector prototypes to a test beam they enter a parallel world. Many basic needs are put on hold – the need for sunlight, regular meals or eight hours […]
