Writing the LOI is like “creating a painting”
LOI editors are proud of their work – and glad it's over

Some 400 pages of calculations, simulations, detector descriptions, estimates, some 1000 signatories from all round the world, hours spent on the phone or clustered around conference tables – a lot of hard work and careful thinking went into the Letters of Intent (LOI). Each of the three submitted letters – for ILD, for SiD and for the 4th concept or 4th for short – managed to meet the deadline, and even though they didn't manage to stick to the recommended page limit of 100, they were all accepted and are being scrutinised by the international detector advisory group IDAG (see this week’s other feature). This is a story about how an LOI is written, as told by the authors and editors.

Evaluating the ILC detector concepts
“A noteworthy step in the genesis of ILC detectors,” said Michel Davier, chair of IDAG.

Since the end of March, when the detector concept groups delivered their Letters of Intent, the International Detector Advisory Group (IDAG) has been experiencing an intense period. At TILC09 in Japan, the panel worked and interviewed the detector concept groups for three days. All sessions were closed to other participants, but ILC NewsLine wanted to know more about what happened there and understand details about the whole process of detector evaluation.

Finding antimatter in the real world
Theories of physics say that the universe exploded into existence some 13.7 billion years ago with the big bang. At that instant, matter and antimatter existed in equal amounts because the laws of nature require that matter and antimatter be created in pairs.

Austrian participation in CERN
This afternoon, a meeting took place in the Ministry of Science and Research in Vienna between Austrian Science Minister Johannes Hahn, CERN1 Director-General Rolf Heuer, and CERN External Relations Coordinator Felicitas Pauss. In a constructive working meeting, Minister Hahn explained the reasons for wishing to end Austrian membership of CERN at the end of 2010.

Progress on ILC machine-detector interfaces through the detector LOI process
A view of the 4th Detector Concept featuring dual solenoids and end wall current coils |
The TILC09 workshop in Japan from17 to 21 April was particularly notable as it featured the first presentations of the ILC detector Letters of Intent (LOI). Although this process precedes the solicitation of ILC detector proposals or formation of ILC collaborations, it is a very important step in understanding and defining the enabling R&D, understanding interfaces with the machine and assessing the capabilities of ILC detectors. Three LOIs were submitted at the end of March and IDAG, the International Detector Advisory Group reporting to the ILC Research Director, Sakue Yamada, has now begun to assess them towards a validation for the next step, a technical design. This process will be very valuable in guiding the development of a realistic plan and scope for the experimental programme on the same time scale as the accelerator technical design report (TDR) we are preparing, meaning a technical design by the end of 2012.
