Scientific Programme:
JINR participation in international collaborations for the design, creation and improvement of new generation accelerators and colliders by scientific researches and experimental development in the field of particle accelerators physics: design of cryomodules and accelerating structures with superconducting cavities; studies of free electron laser physics, development and construction of diagnostic and accelerator systems applied for ultra short dense bunches in the linear electron accelerators; development and construction of systems applied for formation and diagnostics of ultra short dense bunches in the linear electron accelerators; construction of test facilities for accelerating structures investigation; development and creation of a new generation instrumentation for precision laser metrology of accelerators and detector complexes to increase their luminosity and work parameters. Common investigations in the field of laser-plasma accelerators. On a base of electron linac bench: construction of the stand for calibration of electromagnetic calorimeters and investigations of other detectors and their characteristics; creation of complex for the laboratory and practical trainings of students and PhD students - future engineers from JINR member states.
