Organising the post-2012 era

| 28 June 2012 The new Linear Collider Organisation is being planned with a united ILC and CLIC physics and detector effort. This is a natural step, but the devil is in the details. While there has been a lot of fruitful collaboration in the past, there also remain differences that must be considered. Category: Research Director's Report | Tagged: , , , , ,

Past and future of the Worldwide Study

| 22 September 2011 The groundwork for the Worldwide Study, a global linear collider physics and detector partnership, was laid more than ten years ago. Since then it has been a driving force for coordination and development of physics studies and detector R&D around the world. Category: Research Director's Report | Tagged: ,

ILC community meets in Oregon for ALCPG11

| 17 February 2011 On the eve of the 2011 ILC Americas regional meeting meeting, Jim Brau reports on the progress which has been achieved in the ILC detector and physics field since the last meeting in 2009. Category: Research Director's Report | Tagged: , ,

SiD moving forward

| 16 December 2010 The SiD (Silicon Detector) Collaboration met in a workshop at the University of Oregon in Eugene from 15-17 November to review progress, discuss plans, and further organise its effort for the Detailed Baseline Design (DBD) report due at the end of 2012. -- Jim Brau and Andy White for SiD Category: Research Director's Report | Tagged: , ,

Optimal ILC physics performance at acceptable cost and risk

| 15 July 2010 The [SB2009 Working Group] established quantitatively that the low-energy performance of SB2009 was a serious concern for optimal performance at lower energies, such as at and just above the threshold for Z-Higgs (210-350 GeV), an assumed key operating point for the measurement of Higgs properties. In response to these comments from the physics community, the GDE began investigations of concepts which could improve the low-energy luminosity. Category: Research Director's Report | Tagged:

Optimising the value of the ILC

| 21 January 2010 [...] Sakue has created a working group of people who are able to simulate the effect of SB2009 parameters on physics performance. Some changes are expected to have little effect on the physics performance of the ILC, while other changes potentially may have important negative implications, challenging the fulfillment of the Parameters and performance.

Cautious optimism for US-university detector R&D funding

| 22 January 2009 Several recent positive developments are moving us forward on the path towards realising the ILC. These include excellent detector R&D results and significant progress on the Letters of Intent (LOI) for the various detector concepts. Category: Research Director's Report | Tagged: , ,

New US Strategic plan for particle physics recommends restored participation in ILC R&D

| 12 June 2008 This past year, our global collaboration was derailed by funding cuts for the ILC in the UK and in the US. (...) Our dedication and perseverance have been challenged, but the science has not changed: particle physics will need a high-energy linear collider. In the US, a new strategic plan for the funding agencies restates the importance of a lepton collider to advances in particle physics. Category: Research Director's Report | Tagged: , ,
