Studies of Systems of New-Generation
Accelerators and Colliders for Fundamental and Applied Research


Leaders:

G.D. Shirkov
V.V. Glagolev



Participating countries and international organizations:

Armenia, Belarus, CERN, Georgia, Germany, Italy, Russia, Slovakia, Uzbekistan.


Issues addressed and main goals of research:

Creating a network of five Precision Laser Inclinometers (PLI); creating a prototype of an amplitude interferometric length meter for a length of 16 m; creating a prototype of a laser reference line for a length of 128 m; creating a prototype of a seismic-stabilized research platform based on the PLI. Investigation of various carbon-based transmission photocathodes, installation of the second beamline with a 213-nm laser at the photogun bench, development of the photoinjector bench: 150-KeV electron energy achievement, development of radiation safety, interlock and control systems. Development, determination of design parameters and commissioning of the LINAC-200 linear electron accelerator with the aim of its experimental and educational applications. Optimization of accelerator parameters for users. Maintenance of the FLASH infrared undulator and participation in its experimental program, as well as in the new undulator development; development of photon diagnostics for FLASH, FLASH2 and XFEL and experiment participation. Experimental investigations of 3D ellipsoidal shape electron bunches with small emittances at PITZ with the new laser system. Preparation of proposals and start of JINR participation in international collaborations on future high-energy colliders.


Expected results in the current year:

  • Fabrication of the nanostructured carbon photocathodes and investigation of their electrophysical properties (λ = 213 / 266 nm). Assembling of the pepper-pot emittance measurement system main components for the photoinjector bench. Vacuum system assembling and pumping. Design, fabrication and assembling of a cryopump for the bench vacuum system. Assembling, tuning and calibration of the nanosecond range high-sensitivity electron bunch charge sensor prototype. Bench startup with the energy of 120 keV.

  • Optimization of the LINAC-200 beam parameters at 200 MeV. Extraction of the beam with wide-range parameters from single electrons to 30 mA with the repetition rate up to 25 Hz into the atmosphere, optimization of beam parameters for users. Manufacturing of the beam parallel transfer system (DLNP program) after the 2nd and 3rd accelerating stations. Modernization of the cooling, control and interlock systems.

  • Development and creation of an absolute length meter with micron resolution for lengths of 1-10 m. Determining the sensitivity of the meter on a length of 0.1 m. R&D of the creation of a 128-meter laser reference line with the ability to measure the spatial position of the Measured Point on a controlled object (non-destructive testing). Measurement of microseismic activity at CERN and assessment of the effect of microseisms on the luminosity of the LHC collider, development of technical specifications for design and software of a small-sized PLI.

  • Investigation of the electron beam and FEL physics: generation of infrared radiation from the JINR undulator at FLASH and measurements of a longitudinal bunch profile on the basis of this radiation; diagnostics of electron bunches at FLASH2 by using microchannel plate detectors; test experiments with XFEL microchannel plate detectors on the PETRA III synchrotron sources, experimental investigations of the 3D ellipsoidal shape electron bunches at PITZ with the new laser system.

  • Preparation of proposals for JINR participation in international collaborations on future high-energy colliders. Analysis of 6-T high-efficient dipole magnets aimed at the FCC "low energy" pp-collider option at CERN.
