ILD community determines parameters for reference detector
Discussions during the ILD meeting in Cambridge, UK, about the detector concept parameters continued in the coffee breaks...

“I know it is painful — nobody expected it to be fun,” Ties Behnke, standing in front of a detector audience in a lecture hall at Cambridge University, summed up the at times rather heated discussions at the ILD meeting two weeks ago. “But we are making progress and it actually turned out to be fun!” The scientists working on the International Large Detector concept ILD had met for the second time this year to discuss the set-up of their future masterpiece.
The ILD group formed about a year ago from the former GLD and LDC detector concept groups. Both concepts had their plans for trackers, calorimeters and the detector set-up as a whole. “This was actually a birthday of ILD. We have been working on two different detector concepts up to this meeting. Now, we have a single concept to work on,” said Hitoshi Yamamoto. They have also agreed to have a single software framework managed jointly.
The deadline for submission of a common Letter of Intent (LOI) is in March 2009, and many parameters have to be set before work can start in earnest.

World beam test tour at Fermilab
Students working on assembling and testing |
The International Linear Collider requires a detector with excellent performance to fully exploit its physics potential. In order to meet this challenge, significant improvements in the calorimetric performance are needed compared to previous generations of detectors, and new technologies and techniques are being developed. To test those technologies and techniques with particle beams, scientists are travelling around the world, to where beamlines with particle beams for tests are available.

Independent panel passes judgement on UK physics
Wakeham review praises state of discipline and recommends ways it can move forward.
...The panel did recommend that more could be done to protect funding for particle physics and astronomy. In particular it suggested that the council appeal to the government for additional funding for particle physics and astronomy to "avoid the undesired tensioning of these grants and facilities support against national facilities".

Commentary: UK physics gets a health check
The field is healthy, says Bill Wakeham, but scientists need to reclaim the intellectual ownership of research at the margins of the discipline such as medical or atmospheric physics.

Britain's reputation as physics leader 'harmed by £80m crisis'
... That echoed the MPs' report, which said that pulling out of projects such as the International Linear Collider, a next-generation atom-smasher that would succeed the Large Hadron Collider, had made Britain appear to be an “unreliable and incompetent” international partner.

Editorial: Two decades and counting...
...It will be intriguing to think what my successor in 20 years’ time — assuming that Physics World still exists — will make of this status report. By then, practical quantum computers could well be used for research and high-temperature superconductors will be common in power cables. The International Linear Collider is likely to be up and running, and fusion power should be nearing as a commercial reality.

Le LHC aura-t-il un successeur ?
...Suspendue aux résultats du LHC, la décision de maintenir l'ILC ou de se tourner vers le Clic devrait être prise vers 2010-2012. Le choix ne sera pas que scientifique : les arbitrages financiers et politiques pèseront aussi de tout leur poids.

Achieving tiny beam spot sizes with ATF2
The layout for the ATF and ATF-2 at KEK |
The ILC's beams pass through each accelerating element once before they are directed to collide with the beam travelling in the opposite direction. This poses the two main challenges in the ILC: to achieve a very high gradient in the accelerator in order to make it as short as possible while achieving the desired energy, and to achieve very small beam spots to maximise the probability of collisions by the crossing beams. The process of creating small beam spots relies on creating low-emittance beams, preserving the emittance during acceleration and transport, and focusing the beams to nanometres just before collision. Last month I had the opportunity to visit the Accelerator Test Facility (ATF) at KEK which creates small emittance beams that will be injected into ATF2, a final-focus beamline that will test the ability to bring the beam to the nanometre-scale beam spot sizes needed for the ILC.

Barry for Vice President
The members of the American Physical Society APS have elected ILC GDE Director Barry Barish as their next vice president. He will start in January 2009 and become president-elect in 2010 and president in 2011. He was also re-elected to the US National Science Board, an independent body of advisors to both the US President and Congress on broad national policy issues related to science and engineering research and education and an
oversight body for the National Science Foundation (NSF). The term will last six years.
