	V.G. Khachatryan, V.H. Petrosyan, A. Sargsyan, A.V. Tsakanian CANDLE SRI, Yerevan, Armenia
	The objective of the study is the simulation of the produced secondary radiation properties when the electron beam halo particles hit collimator walls. Using particle tracking simulation code FLUKA the European XFEL electron beam interaction with the titanium collimator and copper absorber of the undulator intersections as well as FLASH beam interaction with the tapered collimator were simulated. Absorbed dose spatial distribution in the material of the collimators was simulated for the total secondary radiation and its important photon and neutron components. Residual dose rate after irritation of the collimator material by the electron beam was calculated.

	Advanced Research Electron Accelerator Laboratory (AREAL) is a 20 MeV laser driven RF linear accelerator which is being constructed in the CANDLE institute. The construction of phase-1 is finished and at present the machine commissioning is in progress. In phase-1 a photocathode RF gun provides a 5 MeV small emittance electron beam with the 100 pC bunch charge and variable electron bunch length from 0.5 to 8 ps. Two main operation modes are foreseen for this phase – single and multibunch regimes to satisfy experimental demands. We report the status of linac, first experience and nearest machine run schedule. The brief review of the facility, main parameters, performance and first results are presented.

TUPRO078	AREAL Solenoid, Dipole and Steering Magnets Design and Performance	1223
	A.V. Tsakanian, H. Gagiyan, A.A. Gevorgyan, B. Grigoryan, V.G. Khachatryan, M. Manukyan, T.H. Mkrtchyan, S. Naghdalyan, A.S. Simonyan, V. V. Vardanyan CANDLE SRI, Yerevan, Armenia
	The AREAL solenoid, dipole and corrector magnets design, simulations and performance are presented. A solenoid magnet will be used for the focusing of the low energy (E~5MeV) electron beam after RF gun as well as in the beam diagnostic section. The magnetic iron cover of solenoid provides return path for magnetic field screening effectively the field in the outer space and concentrating it inside solenoid gap. The dipole magnet is part of the spectrometer for beam energy spread measurements. An Iron-free corrector magnet design allows independent horizontal and vertical beam steering. The design optimization and magnetic field calculations are performed using CST-EM Studio. A good agreement between measurements and simulations is obtained.
