“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.
