The most effective way to increase the brilliance of synchrotron light sources is the reduction of beam emittance. To improve the CANDLE synchrotron light source performance, a new low emittance facility has been designed with the account of the new developments in magnets fabrication technology of last decade. The lattices for the booster and storage rings are re-designed keeping the geometrical layout of the facilities. The new design provides the beam emittance in storage ring below 5nm with sufficient dynamic aperture. This report presents the main design considerations, the linear and non-linear beam dynamics aspects of the modified facility performance.

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.

In linear accelerators or transfer lines beam-based alignment (BBA) techniques are important tools for beam orbit steering. In this paper BBA correction algorithm based on difference orbit multiple measurements is proposed. Numerical simulation results for European XFEL SASE1 and FLASH undulator section are presented, according to which the orbit alignment can be achieved within accuracy of about 2 microns and 5 microns respectively. The influence of quadrupole gradient errors is also discussed.

The coherent radiation of the relativistic electron beam with helical orbit in circular waveguide is studied. The radiation field configuration is obtained using modal expansion technique. For short electron bunches the coherent part of radiation is evaluated. The coherent radiation effects on the bunch performance are analyzed.

Advanced Research Electron Accelerator Laboratory (AREAL) based on photo cathode RF gun is under construction at CANDLE. In current stage the gun section is under commissioning (phase 1). This paper presents the main characteristics of gun section beam diagnostics and the architecture of AREAL control system. The diagnostic system includes the measurements of the beam main parameters and its longitudinal and transverse phase space characteristics. The results of the facility first phase commissioning are summarized from the beam diagnostic and control point of view.

Following the design specifications of the Advanced Research Electron Accelerator Laboratory (AREAL), a reliable distributed cooling system for the AREAL linear accelerator has been developed. The cooling system provides a high accuracy temperature control for the electron gun, klystron and the magnets. The main requirements and technical solutions for various accelerator components cooling units are presented, including the local and remote control.
