"J-PARC Outreach Lecture" held in June 2026
◆◇◆Narusawa Elementary School, Hitachi City (Tuesday, June 2, 2026) ◆◇◆
Dr. KAMIYA Junichiro of the Accelerators Division delivered a lecture and experimental workshop titled "Let's Explore the Invisible World of Vacuum" at Narusawa Elementary School in Hitachi City.
Twenty-six fourth-grade students learned what happens to objects such as marshmallows and balloons in a vacuum through a series of experiments. The students watched with great interest as the marshmallows and balloons expanded when placed in a vacuum.
They also took part in various experiments, including the Magdeburg hemispheres experiment and an experiment demonstrating what happens to a feather and a coin when they fall inside a transparent vacuum tube.
Finally, through a vacuum cannon experiment, Dr. KAMIYA explained that vacuum plays an important role in accelerating particles at J-PARC.

◆◇◆Hakuoh University Ashikaga Junior High School, Tochigi Prefecture (Saturday, June 6, 2026) ◆◇◆
Dr. OTANI Masashi of the Accelerators Division delivered a lecture titled "How Accelerators Reveal the Microscopic World: Muon Acceleration Technology for Probing from Particle Phenomena to Massive Structures" at Hakuoh University Ashikaga Junior High School.
In the lecture, Dr. OTANI explained the principles of particle accelerators and their applications, including medical uses. He also introduced the properties of muons, methods of muon acceleration, and recent technological developments and research in particle physics using muon acceleration technology.
In addition, he presented an ongoing human resource development program for accelerator engineers through the construction of compact accelerators in collaboration with the National Institute of Technology (KOSEN).
According to the post-lecture questionnaire, students showed a strong interest in accelerator technology. Some commented that they would like to learn more about methods for controlling high voltages in multi-stage acceleration systems.
