From Fermilab Today: Fine-tuning the instruments of acceleration

| 26 August 2010 Achieving 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.

The German way to the forum

| 15 July 2010 Some ideas are so good that you have to export them when you move from one country to the other. This is especially the case in a global project like the ILC, where three regions and people from all over the place work together to make sure that whatever the LHC will find, the next generation of particle accelerators can study in detail. So when theorist Gudrid Moortgat-Pick moved from Durham, UK, to Hamburg, Germany, she took the concept of the interdisciplinary linear collider forum with her to create it in Germany. The first meeting of the new working group took place at DESY in June. Category: Around the World | Tagged: , , ,

From DESY: Record wavelength at FLASH

24 June 2010 For the first time, FLASH produced laser light with a wavelength of 4.45 nanometres; thus, DESY's free-electron laser for soft X-ray light considerably beat its previous record of 6.5 nanometres. At the same time, the peak intensity of single light pulses nearly doubled, with 0.3 millijoule. Prior to this, there was a five-month machine upgrade, above all with a significant improvement of the superconducting linear accelerator and the installation of a seeding experiment together with the University of Hamburg.

From DESY: Hamburg accelerates particle physics

17 June 2010 The University of Hamburg and DESY have won a shared Alexander von Humboldt professorship for the development of accelerators and particle physics. The renowned award goes to Professor Brian Foster, currently head of Particle Physics at the University of Oxford in the United Kingdom, the Alexander von Humboldt Foundation and the Federal Ministry of Education and Research announced today. Assuming successful conclusions to negotiations, Foster will receive up to 5 million Euros over a period of five years to fund research into the development and realisation of acceleration technologies for particle physics and continued analysis of data from DESY's flagship accelerator, HERA.

A telescope road movie

| 10 June 2010 I don't usually start stories for ILC NewsLine with the word 'I'. This time I have to make an exception, because for a change I was not merely a spectator and communicator of science, but a facilitator (of sorts). One of the actors in something both very mundane and very exciting: transporting scientific equipment from one lab to another. On Sunday 30 May, the EUDET beam telescope was brought from DESY to CERN, and I was one of its (three) drivers. Category: Around the World | Tagged: , ,

Experts eye the eyes of the future

| 25 February 2010 Sometimes detector projects that are still at a planning stage can tell detector projects that are already taking data what hardware to use. This is certainly the case when the R&D project has been using, trying and testing a technology that the 'old hand' is considering for its upgrade: a relatively new type of sensor called Silicon Photo Multiplier, or SiPM, developed in Russia. A meeting brought experts from all areas that use SiPMs together at DESY in Hamburg, Germany, for two days earlier this week. Category: Around the World | Tagged: , , , ,

Successful beginning of S1 global at KEK

| 28 January 2010 Four superconducting accelerating cavities have been successfully assembled at KEK’s Superconducting RF Test Facility (STF). From 14 to 22 January, the assembly team of technical staff from DESY and Fermilab visited KEK, and completed cavity-string assembly work in the STF cleanroom, making a wonderful start for S1 global, a crucial system test towards realising the International Linear Collider.

From DESY inForm: Old hall – new detectors

12 November 2009 When you plan to move and try to find helpers, they often ask: to which floor? If the DESY people working in the detector lab would depend on the help of friends, they would have difficulties to find volunteers because the answer would be: seventh floor! Everything has to be transported from the ground floor to deep down underground. The HEP groups' detector lab moves from hall 5 to HERA hall west. In order to make room the electronics hut of the still present HERA-B detector was dismantled. Category: Around the World | Tagged: ,

One sheet to plot them all

| 29 October 2009 The idea sounds simple enough: collect all the data that exist in the world on cavities – nine-cell TESLA-style cavities, to be precise – including all tests, manufacturers and achieved gradients and merge it into a common format so that all cavity professionals around the world can extract the data they need to compare cavity performance and learn. Anyone who has ever set up a database and tried to merge existing data sets into one knows: it's not that easy. However, the ILC's accelerator experts have just decided that they will all use a database system developed by DESY to set up the world's first global cavity database. Category: Feature | Tagged: ,

9 mA revisited

| 24 September 2009 The last two weeks were two of the most important (and intense) weeks for accelerator specialists working on the ILC. After a long period of preparation and a series of first tests, they have just finished a period of successfully running the superconducting linear accelerator FLASH at DESY under ILC-like conditions to demonstrate that a long train of electron bunches with high charge can be produced in and travel through the accelerator – and stay there, too. After the ILC-like run, which ended on Monday after long day and night shifts in the control room, FLASH will receive a major upgrade to improve capabilities and performance for the users of the laser light generated by FLASH.
