| Leader: | G.D. Shirkov |
| Deputy: | J.A. Budagov |
Participating countries and international organizations:
Armenia, Belarus, CERN, Germany, Georgia, Italy, Russia, Slovakia.
Issues addressed and main goals of research:
Creating a network of six 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 PLI. Investigation of the various carbon-based transmission photocathodes (mainly carbon-based), installation of the second beamline with the 213 nm laser at the photogun bench, development of the photoinjector bench: 150 KeV electron energy achievement, development of the radiation safety, interlock and control systems. Development, design parameters achievement and commissioning of the LINAC-200 linear electron accelerator with the aim of its experimental and education applications. Optimization of the 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 diagnostic for FLASH, FLASH2 and XFEL and experiments participation. Experimental investigations at formation of 3D ellipsoidal shape electron bunches with small emittances in PITZ with new laser system. Preparation of the proposals and start of the JINR participation in international collaborations for future high-energy colliders.
Expected results in the current year:
- Fabrication of the nanostructured carbon photocathodes and investigation of their
electrophysical properties (
= 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 the cryopump for the bench vacuum
system. Assembling, tuning and calibration of the nanosecond range high-sensitivity
electron bunch charge sensor prototype. Bench startup with 120 keV energy.
- Optimization of the Linac-200 beam parameters at 200 MeV energy. Extraction of the beam
with wide range parameters from single electrons to 30 mA with repetition rate up to 25 Hz
into the atmosphere, optimization of beam parameters for users. Manufacturing of beam
parallel transfer system (LNP program) after 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 0.42 m. R&D on 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 the design and software of small-sized PLI.
- Investigation of electron beam and FEL physics: generation of infrared radiation from JINR undulator at FLASH and measurements of longitudinal bunch profile on basis
of this radiation; diagnostic of electron bunches at FLASH2 by using of microchannel plate detectors; test experiments with XFEL microchannel plate detectors on synchrotron
sources PETRA III, experimental investigations of 3D ellipsoidal shape electron bunches in PITZ with new laser system.
- Preparation of the proposals of the JINR participation in international collaborations for
future high-energy colliders. Analysis of 6 T high efficient dipole magnets aimed at the
FCC "low energy" pp-collider option at CERN.
