Linear collider scientists gather in Japan

| 4 September 2014 It's meeting season in North Japan: a series of workshops held in Ichinoseki as well as in Tokyo brings together linear-collider scientists from all sorts of backgrounds: polarisation, particle sources, detector design, physics studies, and, coming up, machine-detector interface and civil engineering.

From KEK: The fifth POSIPOL workshop held at KEK

10 June 2010 The POSIPOL 2010 workshop was held from 31 May to 2 June at KEK. It was the fifth in the POSIPOL series of workshops dealing with the physics aspects, the design issues, and the open questions concerning a polarised positron source in the framework of the next-generation electron-positron colliders such as the ILC or the Compact Linear Collider Study CLIC. A total of 44 scientists from Europe, Asia and the US attended the workshop, including some via videoconference. The main topic of the POSIPOL 2010 was design of the polarized positron sources for the ILC and for CLIC. The only linear accelerator which used a positron beam was the SLAC Linear Collider (SLC) at SLAC National Accelerator Laboratory in the US "For CLIC, we will need to produce 18 times more positrons than SLC, and 65 times more for the ILC", said Dr. Louis Rinolfi (CERN), who is convener of the ILC/CLIC joint working group for positron studies, "these numbers show how far we are from what where want to be," Rinolfi said.

Creating polarised positron beams

3 July 2008 The PosiPol2008 workshop was held from 16 to 18 June in Hiroshima, Japan. An unfamiliar word, "PosiPol" stands for "polarised positrons", meaning that the "spins" of positrons are aligned when they meet electrons at the centre of a linear collider. The electron beam is designed to be polarised at the ILC, but according to the baseline configuration positrons are unpolarised (or left naturally polarised) because making polarised positron is a difficult task to do.
