TUPAB011	Beam Dynamics Simulation in Two Versions of New Photogun for FCC-ee Electron Injector Linac	1326
	S.M. Polozov, T.V. Bondarenko MEPhI, Moscow, Russia
	New high-energy frontier project FCC is now under development at CERN. The project includes three modes: ee, hh and eh interactions for FCC. New injection system for FCC-ee is planned to consist of new ~ 2-14 GeV electron linac and electron-positron converter. Injector linac should provide two regimes: ~250 pC bunches for injection and ~6 nC bunches for e⁻/e⁺ conversion. Two possible schemes of photogun are comprised and results of beam dynamics simulation in both FCC-ee injection linac photoguns are discussed.

TUPAB012	Comparison of Prismatic and Circular Biperiodical Accelerating Structures of 27 GHz Operating Frequency	1330
	Yu.D. Kliuchevskaia, S.M. Polozov MEPhI, Moscow, Russia
	As known a biperiodical accelerating structure (BAS) represents as a system based on disk loaded waveguide (DLW) operating on Pi/2 mode and is widely used for the compact electron linacs. Earlier such structure with operating frequency of 27 GHz was proposed for medical application and beam dynamics simulations and electrodynamics modeling were done [1-2]. It was shown that such structure manufacturing should have very high accuracy and can be manufactured using electro erosive technology only. It is very complex for axi-symmetrical geometry to use such technology. Interesting option will to use a prismatic geometry BAS. In this report the design of a prismatic and disk-loaded BAS will discus, simulation results and analysis will presented.

	The new accelerator complex Nuclotron-based Ion Collider fAcility (NICA) is now under development and construction at JINR, Dubna. This complex is assumed to operate using two injectors: the Alvarez-type linac LU-20 as injector of light ions, polarized protons and deuterons and a new linac HILAc - injector of heavy ions beams. Old DC for-injector of the LU-20, which operated from 1974, is replaced by the new RFQ accelerator, which was commissioned in spring 2016. The first Nuclotron technological run with new fore-injector was performed in June 2016. Beams of D⁺ and H²⁺ were successfully injected and accelerated in the Nuclotron ring. Main results of the RFQ commissioning and the first Nuclotron run with new for-injector is discussed in this paper.

WEPVA013	Small Size Neutron Generators with Laser Induced Plasma and Electron Conductivity Suppressed by Magnetic Field	3278
	V.I. Rashchikov, S.M. Polozov, A.E. Shikanov MEPhI, Moscow, Russia
	Coaxial neutron tubes generators with transverse dimension less than 0.1 m are discussed. Laser plasma containing deuterons is created at the anode by a focused laser beam. Deuterons from plasma are accelerated by pulse voltage and produces neutrons on cylindrical cathode symmetrically surrounding the anode. Magnetic field was used to suppress knock on parasitic electron current in the accelerating gap. Computer simulation with code SUMA* was fulfilled to investigate output neutron flow dependence on laser produced plasma density, magnetic fields and pulse voltage shapes and amplitudes, cathode and anode materials. The results obtained are in a good agreement with conducted experiments on diode with electron conductivity suppressed by magnetic field produced by permanent magnets*.
