## Abstract

A possibility to construct high-intensity tunable monochromatic {gamma}-source at HERA and LEP (LEP-2) is discussed. It is proposed to produce {gamma}-quanta by means of Compton backscattering of laser photons on electrons of the collider. The laser light wavelength is chosen in such a way that after the scattering, the electron does not leave the separatrix. So as the probability of the scattering is rather small, energy oscillations are damped prior the next scattering. As a result, the proposed source can operate in `parasitic` mode not interfering with the main mode of the collider operation. It is proposed to install at the colliders HERA and LEP tunable free-electron lasers operating at 100-400 {mu}m wavelength band with the peak and average output power {approx} 10 MW and {approx} 1 kw, respectively. It will result in the intensity of the {gamma}-source {approx} 10{sup 14} s{sup -1} with tunable {gamma}-quantum energy up to 150 MeV, 250 MeV and 500 MeV for the HERA, LEP and LEP 2, respectively. Such a {gamma}-quantum source will reveal unique possibilities for precision investigations in nuclear physics. 22 refs., 3 figs., 2 tabs.
