STF – Getting ready for the experience

| 1 March 2007 An important prerequisite for building the ILC is to establish the design and manufacturing of major and vital components, such as cryomodules for the main linacs through realistic operating conditions. The Tesla Test Facility (FLASH) at DESY and Fermilab’s ILC Test Area have been pursued to play critical roles in the European and American regions to this end. KEK also aims to serve as an Asian regional center for the main linac technology, and their STF (Superconducting RF Test Facility) and R&D programs are a manifestation of its endeavour. Many members of STF from KEK are active members in the GDE and in close collaborative relationships with colleagues from DESY, INFN, Orsay, FNAL, JLab, Cornell and SLAC. Major laboratories from China, Korea, and India, have expressed their interests or have already begun interactions with the programme at STF in various forms also.

Argonne-Fermilab BCP System Coming Together

| 4 January 2007 To make the superconducting cavities for the ILC sparkle, they must undergo a series of surface treatments to make them as clean and pure as possible – a necessity for achieving high accelerating gradients. Electropolishing and Buffered Chemical Polishing, the two types of chemical treatments required for the cavities, are not simple tasks. They involve tricky chemicals and a detailed recipe for producing the best cavities possible. Category: Feature | Tagged: , , , , , , ,

Unprecedented: 13.1 nm for FLASH!

4 May 2006 When Albrecht Wagner, Chairman of the DESY Directorate, opened his mailbox in the morning of 27 April and found an email about FLASH’s 13.1-nm success, he replied immediately: "This is exciting and fantastic news! Congratulations to the entire team!" FLASH, DESY’s pilot facility for the future European XFEL, produced the shortest wavelength yet. This success was celebrated with a party in DESY’s accelerator control room the night before at 22:10 h. Already after three hours, when the superconducting TESLA Test Facility Linac, equipped with five accelerator modules, reached the designated energy of 700 MeV, the electron bunches that traversed the undulator emitted laser flashes with a wavelength of only 13.1 nm (there’s a plot from the logbook for those who don’t believe it). This is an important step on the way to reach the design value of 6 nm planned for the FLASH facility. With the sixth module which will be installed in the second quarter of 2007, it will be possible to accelerate the electron bunches to 1 GeV and to generate wavelengths of 6 nm.

Fermilab Cools First TESLA Cavity from DESY

| 16 February 2006 On Monday, 6 February, a team of cryogenic engineers and accelerator physicists at Fermilab successfully cooled the first TESLA 9-cell 1.3 GHz cavity to 4.5 K (Kelvin) in the ILC Test Area in the Meson Detector Building (ILCTA-MDB). Travelling to Hamburg, Germany, Fermilab personnel assisted DESY in preparing the "ILC-like" cavity, called Capture Cavity II (CCII), and shipped it to its current home in Batavia, Illinois in August 2005.
