The Belle-II experiment which has been done in Tsukub, Japan conducted by The High Energy Accelerator Research Organization (KEK) has been completed. It can be taken as the step forward by integrating particle detector with powerful accelerator. The word roll-in refers to the operation of moving the entire Belle II detector system from its assembly area to the beam collision point. The Belle II detector’s total weight is about 1400 tons.

What is High Energy Accelerator Research Organization?

  • It is a Japanese organization which made for the purpose to operate the largest particle physics laboratory in Japan situated in Tsukuba, Ibaraki prefecture.
  • It was started in 1997
  • The term KEK is used to refer to the laboratory itself
  • It has been an employment for 695 employees
  • Its main functions is to provide particle accelerations and other infrastructure needed for high-enegry physics, material science, structural biology, radiation science, computing science nuclear science and so on
  • Many experiments have conducted at KEK by the internal and international collaborations that have made use of them
  • Makoto Kobayashi, emeritus professor at KEK, is known globally for his work onCP-violation, and was awarded the 2008 Nobel Prize in Physics.

About Belle-II experiment

  • It consist of an ungraded detector to record the enormous numbers of particle processes that are produced by the Super KEKB accelerator
  • This has been done to design to study violations of the Standard Model of particle physics.
  • It is grand collaboration of 700 scientists from 23 countries including India.
  • It precisely measures elementary particle interactions
  • In this various elementary particles generated from high energy electron-positron collisions will be observed using the 8-meter tall Belle II detector consisting of seven types of subdetectors.
  • The detector will provide measurements of direction and momenta of newly produced particles.
  • Compared to previous Belle experiment, Belle Ⅱ will allow collection of much larger data samples with much improved measurement precision.

India’s contribution

  • It saw an significance as Indian participation both on experimental and theoretical sides
  • The fourth layer of the six-layer i. e. highly sensitive particle detector (the heart of Belle-II) has been built by Indian scientists from Tata Institute of Fundamental Research (TIFR), Mumbai.
  • Scientists from the Indian Institutes of Technology (IIT) Bhubaneswar, Chennai, Guwahati and Hyderabad, Panjab University, Institute of Mathematical Sciences (Chennai), Punjab Agricultural University, Malaviya National Institute of Technology (Jaipur), Indian Institute of Science Education and Research (Mohali) are also participating in this research.
