Infrared synchrotron diagnostics as a new perspective direction in the physics and technology of accelerator and applied experiments

We present the methods and systems of nondestructive diagnostics and study of charged-particle (electron, electron-ion, and proton) beams based on the use of their magnetic-bremsstrahlung (synchrotron) radiation in a wide spectral range, from the ultraviolet to the far long-wave infrared region. We draw attention to the great diversity of problems, both in accelerator experiments (for example, the study of the coherence of synchrotron radiation) and in other, sometimes quite unrelated fields, such as metrology, high-temperature superconductivity, biology, medicine etc., which might be solved by means of infrared synchrotron diagnostics, covering the interval of wavelengths 0.3 - 40 μm, which is much larger than the spectral range that is widely used at present (basically, the range 0.3 - 1.1 μm) in various experiments and investigations. The extension of the spectral range of positively diagnosed synchrotron radiation opens up new possibilities and prospects for solving scientific and applied problems. (author)
