• Scientific ProgrammeGeneral objectives of the
  project are participation in the development of
  the project of linear collider TESLA,
  construction of X-ray free electron laser (XFEL),
  and construction and operation of an VUV/X-ray
  free electron laser at the TESLA Test Facility
  (TTF FEL) at DESY.        Expected main
  results
• Construction of diagnostic system for short
  electron bunches using far infrared coherent
  radiation from an undulator
• Construction of photon beam diagnostic unit and
  characterization of X-ray radiation from X-ray
  FEL at TTF FEL
• Conceptual design of pump-probe FEL facility
  based on two-color FEL amplifier
• Design and manufacturing of undulators and
  wigglers for PETRA and TESLA
• Theoretical work on FEL and beam physics
• Development of diagnostics of cryogenic systems
  and semiconductor cryodetectors.

• Preparation of photon diagnostics for VUV FEL at
  DESY. JINR manufactured control electronics for
  MCP radiation detectors and performed its
  commissioning at the TESLA Test Facility.
• Design and manufacturing of a prototype of
  permanent magnet quadrupole for XFEL and linear
  collider.
• Calculation and optimization of magnetic
  structure of undulators for XFEL.
• Design of an infrared beamline for electron
  bunch length monitor based on coherent infrared
  radiator. A prototype of a collimator with iris
  diaphragm has been manufactured by JINR and
  tested at DESY.
• Studies of beam physics related to production of
  intensive, low-emittance bunches for X-ray FEL.
• Development of elements for cryodiagnostcs for
  XFEL accelerator.
• 38 published papers (18 in refereed journals)
  2004.
