State Research Center – Institute for High Energy Physics (IHEP) is a research organisation in Protvino (near Moscow, Moscow Oblast), Russia. It was established in 1963.^[1]

IHEP signed an agreement concerning scientific and technical co-operation between CERN and the State Committee of the USSR on the Utilization of Atomic Energy in 1967. CERN director-generals Victor Weisskopf and Bernard Gregory played a central role in establishing IHEP’s international collaboration with CERN.^[2]

The institute is known for the particle accelerator U-70 synchrotron launched in 1967 with the maximum proton energy of 70 GeV, which had the largest proton energy in the world for five years.^[2]

The first director of the institute from 1963 to 1974 was Anatoly Logunov. From 1974 to 1993, professor Lev Solovyov (Russian: Лев Дмитриевич Соловьев) served as the director of the institute.^[3] A professor, Nikolai E. Tyurin has been the director of the institute since 2003.^[4]

In 1978, a scientist of the institute, Anatoli Bugorski, was irradiated by an extreme dose of proton beam. His demise was deemed inevitable as the doctors believed he had received a dosage far in excess of what could be considered fatal. However, he survived the accident and continued to work in the institute.^[5]
