| 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:
Creation of the NETWORK of 6 Precision Laser Inclinometers (PLI), creation of the prototype of Amplitude Interferometric Distance Meter for the length of 16 m, creation of the prototype of Laser Fiducial Line for the length of 150 m, creation of the prototype of Seismically-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 major results in the current year:
- Study of the photocathodes based on extremely thin hybrid carbon films, influence of the films composition and diamond/graphite phases ratio on the quantum
efficiency (
= 266 nm). Study of the possibility of the quantum efficiency rising due to the laser beam reflected from the photocathode. Installation of
the second beamline with the 213 nm laser at the photogun bench. Photoinjector bench startup with 150 KeV energy.
- Optimization of the Linac-200 beam parameters at 200 MeV energy. Modernization of the 3rd accelerating station cooling system. Extraction of the beam with wide
range parameters from single electrons up to 30 mA with repletion 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. Work on reconstruction and modernization of the control and interlock systems.
- Microseismic activity measurements at the CERN and GGO and estimate of the microseisms influence on the LHC luminosity; development of the Technical Assignement on the
modernisation of the professional (PLI) hard a soft basement. Designing and construction of prototype of Absolute
Distance Meter with 1 µm resolution for distances of 1-10 m. R&D's for 150 meter long Laser Fiducial Line with possibility of simultaneous measurements of space
coordinates of 6 points on the object controlled with 10 µm precision (the nondestructive control).
- 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 and start of the JINR participation in international collaborations for future high-energy colliders.
