| Popis: | NESTOR is the hard X-ray source that is under commissioning at NSC KIPT. NESTOR based on the Compton scattering of laser photons on relativistic electrons. The structure of the facility can be represented as the following components: a linear accelerator, a transport channel, a storage ring, and a laser-optical system. Electrons are stored in the storage ring for energy of 40-225 MeV, laser photons are accumulated in the optical resonator. The frequencies of laser and electron bunches are synchronized, the interaction point located in the optical resonator. The measurements showed that parameters of the manufactured bending magnets different from the design ones. The bending magnets have different field index, besides the vertical focusing forces are significantly lower than designed ones. The beam dynamics simulation showed that due to decreasing of the vertical focusing the vertical betatron frequency becomes close to the frequency of the integer resonance Q = 2, as a result the vertical motion in the ring is unstable [1]. The second reason for optimization is the need to increase the length of the drift space for optical resonator. The results of optimization are presented in this paper. |
