30 April 2009“How do you ‘see’ neutrons in a scintillator calorimetry?” asks Frank Simon a group of 40 students in the afternoon three days into a five-day “Calorimetry for International Linear Collider” school, held from 22 to 26 April in Beijing. The spring in Beijing is just over outside the classroom on the CCAST campus, and the Chinese students who traveled from many academic institutions across mainland China, such as Tsinghua University, Institute of High Energy Physics Chinese Academy of Science (IHEP) and the University of Science and Technology of China (USTC), eagerly hitch forward in their seats. “Have you played billiards?” An excellent lecturer himself (and a blogger for Quantum Diaries), Simon effectively delivers his ideas as the students speak up. What target would take away momentum from neutrons? Exactly, the mass equivalent of neutrons, the protons. Hydrogen in the active medium makes the detector, and thus the plastic scintillator, sensitive to neutrons.

Rika Takahashi | 24 January 2008From 7 to 11 January, the first school on the Time Projection Chamber (TPC) technology was held at the China Center for Advanced Science and Technology (CCAST) in Beijing. Over 50 students, young scientists and senior researchers from Asia and the rest of the world gathered to learn and discuss about TPC Technology for the International Linear Collider.

Rika Takahashi | 15 November 2007New expressways and subways are under construction. New hotels and apartment buildings are popping up. This city with a population of over 15 million people, which is already big enough, is getting ready for the coming year of increasing visitors who will attend the Olympic Games. This is Beijing.

Barry Barish | 15 November 2007Beijing is a place to mark important ILC milestones. In 2004, the International Committee on Future Accelerators (ICFA) announced the decision to base the ILC acceleration technology on superconducting radiofrequency technology. In February 2007, we released the draft Global Design Effort Reference Design Report (RDR) for the ILC. This past week, in what I anticipate will mark an equally important milestone for the ILC, many of us attended the CCAST ILC Accelerator Workshop and first Asia ILC R&D Seminar under the JSPS Core-University Program.
