	Advanced Research Electron Accelerator Laboratory (AREAL) is an electron linear accelerator project with a laser driven RF gun that has been constructed at CANDLE Synchrotron Research Institute. After the completion of the first phase, which implies the operation of a 5 MeV gun section, the second phase of facility development (energy enhancement up to 50 MeV) is in progress. In the present paper the description of corresponding upgrades for diagnostic and control systems is given.

MOPIK054	Towards the Low Emittance CANDLE Storage Ring	641
	A. Sargsyan, G.A. Amatuni, V. Sahakyan, V.M. Tsakanov, G.S. Zanyan CANDLE SRI, Yerevan, Armenia
	Stimulated by the recent approaches and developments in low emittance lattice design and magnet technology a continuous process of CANDLE storage ring lattice improvement has been launched aiming to keep the project competitive in the field. The main goal of the upgrade program is to bring the beam emittances down to sub-nm level, having the condition of cost and performance efficiency. This paper summarizes the results obtained in the above-mentioned direction. The main design characteristics and linear/nonlinear beam dynamics aspects of the obtained new lattices are presented.

	Advanced Research Electron Accelerator Laboratory (AREAL) is an electron accelerator project based on photo cathode RF gun. First phase of the facility is a 5 MeV energy RF photogun, which is currently under operation. The facility development implies energy upgrade to 50 MeV with further delivery of the electron beam to the undulator sections for Free Electron Laser and coherent undulator radiation generation in MIR and THz frequency ranges respectively. In this report the design study of AREAL 50 MeV facility main systems along with the beam dynamics and characteristics of expected radiation are presented.

WEPAB001	Parallel Operation of SASE1 and SASE3 Undulator Sections of European XFEL	2554
	A. Sargsyan, V. Sahakyan CANDLE SRI, Yerevan, Armenia W. Decking DESY, Hamburg, Germany
	In the current paper the numerical simulation results for parallel (decoupled) operation of SASE1 and SASE3 undulator sections of European XFEL are presented. The study was based on the idea of betatron switcher imple-mentation. It was shown that it is possible to avoid energy spread growth in SASE1 and to reach the saturation in SASE3 in desirable range of radiation wavelengths by a trajectory kick before SASE1 and its correction before SASE3.
