ILD collaborators make progress on detector design options

and | 30 June 2011 With the publication of the Detailed Baseline Design Report in their sights, members of the ILD collaboration work diligently to form realisable models of their detector, ones that take into account both their physics simulations and the nuts and bolts of engineering designs.

Detector activities in the new stage

| 17 December 2009 The physics and detector activity for the ILC entered into a new stage after the validation of the Letters of Intent (LOIs) and following discussions during the American Linear Collider Physics Group (ALCPG) workshop in Albuquerque, US. Close to the turn of the year, I wish to survey what has been going on since then. -- By Sakue Yamada Category: Research Director's Report | Tagged: ,

Progress on ILC detectors

| 17 September 2009 ILD and SiD, two of the three detector concepts that submitted Letters of Intent, have been recommended for validation to Research Director Sakue Yamada by the International Detector Advisory Group (IDAG), chaired by Michel Davier. At their recent meeting in Hamburg, the ILC's Steering Committee endorsed the IDAG recommendations. This means that the R&D collaborations working on detector technologies and prototypes for the two ILC detector concepts ILD, the International Large Detector concept, and SiD, the Silicon Detector Design Study, will continue under full steam in their work towards the best design for detectors to understand collisions at the future ILC. The third detector concept that submitted an LOI, called '4th', was not validated. However, IDAG recommended that R&D on dual readout calorimetry done for 4th in a collaboration of many institutes should be supported in view of its potential for higher energy colliders.

Validation made of the Letters of Intent

| 17 September 2009 (...) The conclusion is that the International Large Detector concept (ILD) and the Silicon Detector Design Study concept (SiD) are recommended for validation as complementary detectors to go on with detailed design and that the dual-readout calorimeter technology is encouraged to be further developed. -- By Sakue Yamada Category: Research Director's Report | Tagged: ,

Planning for the next steps

| 20 August 2009 (...) It is time for us to prepare for the next step, namely to consider what the validated detector groups need to accomplish through the following period, till 2012. Category: Research Director's Report | Tagged: ,

Evaluating the ILC detector concepts

| 14 May 2009 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.

Writing the LOI is like ‘creating a painting’

| 14 May 2009 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. Category: Feature | Tagged: , ,

Progress on ILC machine-detector interfaces through the detector LOI process

| 14 May 2009 Compared to most accelerators, the ILC will have a much more intimate and complex set of interfaces between the machine and the detectors (MDI). Category: Director's Corner | Tagged: , , , , ,

Letters of Intent were submitted

| 16 April 2009 The three ILC detector concept groups, ILD, SiD and 4th, submitted their Letters of Intent (LOIs) by the due date, 31 March. Category: Research Director's Report | Tagged: , ,

Life after the LOI

19 March 2009 A Silicon Detector (SiD) workshop was held at SLAC from 2 to 4 March, with the express purpose of reviewing the status of the SiD Letter of Intent, organising the final steps in its completion, and beginning to think of life after the LOI. Category: Feature | Tagged: , ,
