	Funding: This work is supported by the Russian Science Foundation (grant #19-12-00212). Project of high-power long-pulse THz-band FEL is under development in collaboration between BINP (Novosibirsk) and IAP RAS (N.Novgorod) driven by the linac LIU 5 - 20 MeV / 2 kA / 200 ns. The aim of this project is to achieve a record sub-GW power level and pulse energy content up to 10 - 100 J at THz frequencies. Principal problems in realization of this generator include: formation of the electron beam with parameters acceptable for operation in the short-wavelength ranges, development of undulator for pumping operating transverse oscillations in the beam, and elaboration of electrodynamic system that can provide stable narrow-band oscillation regime in a strongly oversized interaction space. Initial proof-of-principle experiments are planned to start at the LIU-5 accelerator in the 0.3 THz frequency range, with prospects of transition to 0.6 THz range and higher frequencies after positive results would be demonstrated. In the report, the design parameters of the FEL project are discussed. Results of electron-optical experiments on the beam formation are presented. Structural elements of the FEL magnetic system based on helical undulator and a guide solenoid that provides intense beam transportation were elaborated. An electrodynamic system was proposed exploiting advanced Bragg structures, which have significantly improved selective properties. Structures of such type were designed with the diameter of 20 and 40 wavelengths for operation in specified frequency ranges.

WEPSC22	The Status of Dipole of CR FAIR
	A.A. Starostenko, V. Dokutovich, A.Yu. Pakhomov, K.K. Riabchenko, T.V. Rybitskaya, D.V. Senkov, A.S. Tsyganov, K.V. Zhilyaev BINP SB RAS, Novosibirsk, Russia
	The status of Dipole of CR FAIR are presented, also key points of Dipole construction briefly described. CR FAIR is a special storage ring where the main emphasis is placed on efficient collecting and stochastic pre-cooling of intense beams of stable ions, rare isotopes or antiprotons. This DIpole is iron-based electromagnet with straight pole, sector form is realized by cutting ends. The maximum field value is 1.6 T. The integrated over the length of the magnet field quality as a function of radius is dBl/Bl = ±1*10^-4 with 190 mm good field region as required from the beam dynamics simulations. This challenging field quality is necessary mainly for precise experiments with ion beam in ISO regime. The first prototype has been manufactured at the end of 2020. Further we describe features of the dipole, measurements of magnetic field and ways for achieving of required field quality.

WEPSC24	Development of Dipole Magnets for the Storage Ring of the SKIF
	K.K. Riabchenko, T.V. Rybitskaya, A.A. Starostenko BINP SB RAS, Novosibirsk, Russia
	In 2019, work on the design of a series of magnetic elements for the SKIF synchrotron source began. SKIF (Siberian ring photon source) is a fourth generation synchrotron radiation source. This installation will consist of 3 main parts: a linear accelerator with an energy of 200 MeV; a booster - a synchrotron with a maximum energy of 3 GeV and an orbit length of 158 m; storage ring with 16-fold symmetry, energy 3 GeV and a perimeter of 476 m Thanks to this synchrotron source, it will be possible to: receive beams of micro- and nano-sizes; to carry out X-ray structural analysis; study shock-wave, hypersonic and explosive processes; investigate the local and magnetic structure of matter. Within the framework of this project, 3D modeling of several types of dipole magnets was carried out for the storage ring: 1. C-designed dipole magnets (BMA) with an effective length of Leff = 69 cm and a magnetic field in the center of B = 0.53 T, which will be located in the rectilinear intervals of the ring with large beta-x; 2. C-designed dipole magnets (BDA) with Leff = 130 cm, magnetic field in the center B = 0.55 T, gradient G = -7.9 T / m, which will be in the soft X-ray region; 3. C-designed dipole magnets (BDC) with Leff = 47 cm, magnetic field in the center B = 0.46 T, gradient G = -10.7 T / m, which will be located in the hard X-ray cell; 4. Permanent magnet with a field of B = 2 T. The required field quality for the dipoles under consideration should be no worse than 5 × 10^-4.
