Theoretical studies at the Institute of Theoretical and Experimental Physics (ITEP, Moscow): Past, present, and future

Basic results obtained by theorical physicists at the Institute of Theoretical and Experimental Physics (ITEP, Moscow) over the 60 years of its existence are reviewed.     

6-m spectrometer of the Institute of Theoretical and Experimental Physics (ITEP, Moscow)

The history of the development and construction of the ITEP-MIS 6-m magnetic spectrometer is reported. Research studies performed by the ITEP-MIS group over a period of more than 30 years of spectrometer existence is surveyed. The results obtained by studying the narrow resonances f _j(2220) and X(1070) are presented.     

On the history of the Institute of Theoretical and Experimental Physics (ITEP, Moscow)

A survey of investigations performed at the Institute of Theoretical and Experimental Physics (ITEP, Moscow) in the realms of low-energy physics from the foundation of the institute to the present time is given.     

Institute of Theoretical and Experimental Physics (ITEP, Moscow) in the H1 experiment

A group of researchers from the Institute of Theoretical and Experimental Physics (ITEP, Moscow) took part at almost all stages of the H1 experiment performed at the HERA collider (Hamburg) in order to study lepton-proton interactions at high energies. Several subdetectors of the H1 detector were developed, designed, and constructed at the ITEP industrial workshop and domestic enterprises. In particular, the ITEP staff participated in assembling and tunning the equipment, servicing the detector and the data acquisition system, and analyzing and presenting the results. Researchers from ITEP have been playing a crucial role at many stages of the experiment to the present day.     

Investigation of double-beta decay at the Institute of Theoretical and Experimental Physics (ITEP, Moscow)

Investigation of neutrinoless double-beta (2β0ν) decay is presently being considered as one of the most important problems in particle physics and cosmology Interest in the problem was quickened by the observation of neutrino oscillations. The results of oscillation experiments determine the mass differences between different neutrino flavors, and the observation of neutrinoless decay may fix the absolute scale and the hierarchy of the neutrino masses. Investigation of 2β0ν decay is the most efficient method for solving the problem of whether the neutrino is a Dirae or a Majorana particle, Physicists from the Institute of Theoretical and Experimental Physics (ITEP, Moscow) have been participating actively in solving this problem. They initiated and pioneered the application of semiconductor detectors manufactured from enriched germanium to searches for the double-beta decay of ⁷⁶Ge. Investigations with ⁷⁶Ge provided the most important results. At present, ITEP physicists are taking active part in four very large projects, GERDA. Majorana, EXO, and NEMO, which are capable of recording 2β0ν decay at a Majorana neutrino mass of 〈m _ν〉 ≈ 10^?2 eV.     

On the history of the Linear Accelerator Department at the Institute for Theoretical and Experimental Physics (ITEP, Moscow)

These memoirs are devoted to the Institute’s anniversary and present the history of the Linear Accelerator Department at ITEP. Some studies are described in which I was involved. During more than 40 years. I worked with Professor I.M. Kapchinsky (1919–1993), a world-renowned scientist, the founder of the department. References are given to Kapchinsky’s monographs and to some of the works that were performed under his supervision and were published in proceedings of accelerator conferences. Many active scientists, engineers, and technicians are mentioned who participate in the achievements of the department, which made a significant contribution to the development of accelerator science and engineering in Russia and worldwide.

On previous and present investigations of resonance gamma-ray interaction with nuclei at the Institute of Theoretical and Experimental Physics (ITEP, Moscow)

A brief survey of theoretical and experimental work that is devoted to studying the resonance absorption and scattering of gamma rays by nuclei and which was initiated at the Institute of Theoretical and Experimental Physics (ITEP, Moscow) in the 1950s and has been continued to date is given. Investigations of various versions of interaction in beta decay, magnetic-field-perturbed angular distributions of resonantly scattered gamma rays, the problem of the Mössbauer gamma resonance of long-lived isomeric states of nuclei, and the resonance scattering of annihilation photons by nuclei are described.
