Registration Filling Up for Single Crystal Workshop
A conveyor leads to a processing plant at the Araxá niobium mine. |
On 30 October to 1 November, the Single Crystal Niobium Technology Workshop will bring engineers, scientists and technicians together at the site of the world's largest niobium mine in Araxá, Brazil – an event that may be unique for accelerator history. The workshop will explore the manufacturing of large grain or single crystal niobium, a potentially cost-saving direction for superconducting radiofrequency (SRF) cavity technology.
Large grain or single crystal niobium may potentially reduce accelerator capital costs by eliminating certain expensive cavity surface treatments (See ILC NewsLine, 13 July 2006).
The workshop will be a forum for discussion on the current status of the technology for producing 280 mm diameter niobium single crystal ingots for large-scale high gradient applications of SRF linacs, such as the ILC.

High Performance Coupler

At the ILC, electrons and positrons will be accelerated in superconducting cavities – tens of thousands of them. The cavities are surrounded by ultra-cold liquid helium (minus 271 degrees Celsius) in cryomodules, giant cold boxes to keep the cavities and liquid helium cold with a temperature difference of nearly 300 degrees Celsius over a distance of 60 cm. Yet each cavity has to be filled with powerful electromagnetic waves to give enough acceleration power to the electrons and positrons.
A klystron generates 500-kilowatt electromagnetic waves at a pulse width of 1.5 milliseconds, five times per second. This momentary energy amount is equal to turning on 1-kilowatt electric heaters in five hundreds houses at the same time. These waves have to be passed through the microwave duct into the cavities without causing significant power loss or wave reflections.

Make way for an ILC test beam! This week, workers began removing the Chicago Cyclotron magnet from the New Muon building at Fermilab. The giant magnet was originally part of the Chicago Cyclotron, made famous when Enrico Fermi and his colleagues at the University of Chicago used it to show that particles called "pions" are largely responsible for the force that holds protons together in the nucleus of an atom. Once the magnet is put out to pasture, work will begin to convert the building into a test beam facility for the ILC.

Particle Physics Podcast
How did the Universe begin? What are the forces that hold the world together? What is matter made of? Researchers find answers to these questions with the help of enormous particle accelerators. A podcast about elementary particle physics and the origin of the universe (in German), including an interview with Rolf-Dieter Heuer (DESY).

More Reflections on VLCW06: The ILC Reference Design
A new study reported at Vancouver indicates that it may be possible to contain emittance growth in an earth’s curvature following main linac, which is our baseline configuration. |
Last week I discussed the physics and detector part of the joint American Linear Collider Planning Group (ALCPG) and GDE workshop (VLCW06) held in Vancouver from 19-23 July. The GDE portion of the meeting focused on preparations for the Reference Design Report and had very large participation -- about 200 scientists and engineers. Participants reported on important progress on the accelerator design, as well as success in obtaining a first-cut at the costing of most components for the baseline machine.

EUDET Annual Meeting - Open for All!
The EUDET project, made up of 31 European institutes and by now 23 global associates, will hold its first Annual Meeting from 18 to 20 October 2006 at the Max-Planck-Institut für Physik in Munich, Germany.
After the successful Kick-off Meeting last February at DESY (see ILC Newsline article) which served to refine ideas and plans, the upcoming event will focus on the project's achievements of the first year.
EUDET is funded by the European Union and provides support for the development of vertexing, tracking and calorimeter prototypes as well as for the simulation and analysis software framework. The scientific programme is embedded in the international R&D efforts for ILC detectors, and several non-European institutes already contribute significantly to the project. Further development of the international collaboration is highly welcomed by the EUDET consortium to maximise the benefit for the ILC. Therefore the EUDET Annual Meeting is open to all interested people.
