Greetings from Representative Director of the Foundation of High Energy Accelerator Science (HEAS)

　　The Foundation was established in 1977 and has a history of more than 40 years, which is even older than that of the Accelerator Society of Japan. At that time, The Japanese community in high-energy physics nor accelerator science was not yet a major player in the world. In 1983, the Photon Factory (PF), which was the first in the world to provide orbital synchrotron radiation as a laboratory probe, was put into operation. In 1986, the electron-positron collider TRISTAN achieved the world's highest collision energy at the time, thanks to the full-scale use of superconducting acceleration cavities. Thus, Japan's high-energy accelerators and physics have reached at the world's front-line in reality. In 1999, the B Factory, which began operation using the technology, the facilities, and human resources developed at TRISTAN, competed with the SLAC in the U.S., its long-time mentor, now as an equal competitor in performance. It produced numerous breakthroughs in high-brilliance electron accelerator technology and provided the Belle experiment the world-highest luminosity collision. It is well known that the Belle experiment thus enabled the final verification of the Kobayashi-Maskawa theory and brought the Nobel Prize to Dr. Kobayashi and Dr. Maskawa.
　 In 2009, the 12 GeV proton synchrotron, which had been Japan's first high-energy accelerator at the time of the establishment of the Foundation, was reborn as J-PARC in the Tokai-Mura, which now provides beams containing the world's highest number of protons per pulse for both the neutron source using a 3GeV synchrotron and for the neutrino beam using a 30 GeV synchrotron.
　 　As seen above, the history of the Foundation has completely synchronized with the Japan's rise to the top level of accelerator science in the world, and it truly shows the Foundation has played an important role. With those world class performance accelerators developed and operated in Japan, we can provide places for an international collaboration where researchers of basic science gather from all over the world.
　 Unfortunately, in recent years, it has been pointed out that Japan's status has declined significantly in many fields in which Japan once boasted as a global hub. Under these circumstances, the accelerator-related field, which is still dominant as a global base, is of unprecedented significance, and it is expected that this field will continue to serve as a driving force for promoting next-generation innovation world wide. In this respect, closer collaboration between industry and academia for researchers and engineers related to accelerator science is required more than ever. We would like to ask for your continued support and cooperation for the Foundation of High Energy Accelerator Science (HEAS) from everyone in the fields related to accelerator science, such as industry, academia, and governments.
