ILC Detectors: more news since last IDAG meeting

|
We have gained several helpful inputs from the new system of the International Detector Advisory Group (IDAG) monitoring global detectors after the validation. The IDAG report after the Beijing meeting suggests several new measures. Even during the discussion, we already received several useful remarks, some of which were described in my last article. I wish to add one more, namely the nature of the detailed baseline design report which we are going to produce in 2012 to summarise the entire activity of the Detector Letter of Intent (LOI) process. There was a question as to whom the document will be addressed to. Formally such report should be given to International Linear Collider Steering Committee, the mother body of the entire ILC activities. But the report will go further and we need to think more precisely who may actually read it and what it should contain. The question further indicated that we need to share a common idea on the nature of the detailed baseline document.

From DESY: Hamburg accelerates particle physics
Alexander von Humboldt professorship for university and DESY granted
Brian Foster |
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.

"God Particle" May Be Five Distinct Particles, New Evidence Shows
...Though "quite provocative," the results are still preliminary, Quigg stressed. “I know of nothing to make me explicitly doubt the result, but when something is so unexpected and yet so subtle it bears taking time and taking a deep breath,” Quigg said. “It's important not to jump up and down too soon about this.”...

New measurements from Fermilab's MINOS experiment suggest a difference in a key property of neutrinos and antineutrinos
"Batavia, Ill. - Scientists of the MINOS experiment at the Department of Energy's Fermi National Accelerator laboratory today (June 14) announced the world's most precise measurement to date of the parameters that govern antineutrino oscillations, the back-and-forth transformations of antineutrinos from one type to another. ..."

Superconducting RF cavity industrialisation
Hiroaki Umezawa of Tokyo Denkai Co. showed how ILC will put very large new demands on the world production of high purity niobium |
Producing high gradient superconducting radiofrequency (SCRF) cavities that meet our demanding performance goals, are affordable and can be produced by industry represents one of the largest challenges on the way to making a solid project proposal for the ILC. The present 500-GeV ILC design requires about 18,000 nine-cell one-metre long niobium cavities (including spares) yielding an average operational field gradient of 31.5 megavolts per metre (MV/m). Although we can gain much experience from other projects (XFEL, Project X, etc) and from our own R&D programme, developing a worldwide capability to produce our cavities in industry represents an enormous challenge – one we need to address now. In that regard, a special satellite workshop on ILC cavity industrialisation was held in conjunction with the first IPAC meeting last month in Kyoto, Japan.

What is it? Tune in!
Detail of a cavity tuning machine. Image: Thomas Zoufal, DESY
This one was tough for anyone who's never seen one of these, and blindingly obvious for those who have: the little motors, the track and the support structure are of course part of a cavity tuning machine. Congratulation to Toshi Shishido from KEK who was the first one to get the answer right. Tuning machines make sure that all the cavities' cells have the right shape to receive the radiofrequency waves that accelerate the particles. Four of these machine have been built at DESY, and two weeks ago the Fermilab-designed control racks arrived from the US. Machines and controls will be commissioned next week, and eventually one machine will be used for cavity tuning at Fermilab, one at KEK, and two at DESY or companies who work for DESY. Their first job is to get European XFEL cavities into the right shape, afterwards they will be used for ILC R&D.
