Deputies:	G.V. Trubnikov E.M. Syresin

Participating Countries, Institutes and International Organizations:
Belarus, Bulgaria, CERN, Germany, Greece, Italy, Japan, Poland, Russia, Slovac Republic, United Kingdom, Ukraine, USA.

Scientific Programme:
R&D work in particle accelerator physics and engineering, construction of the free electron laser with the aim to prepare proposals for the project of JINR participation in international collaboration on construction of the future Linear Collider (CLIC/ILC). Studies of free electron laser physics, development and construction of systems applied for formation and diagnostics of ultra short dense bunches in the linear electron accelerators. Construction of the generator of direct positronium fluxes for study of new particles and "new physics", construction of the installation for positron annihilation spectroscopy. Study of cryomodule components and SC cavities. High precision lase metrology. R&D for laser-plasma accelerators.

Expected main results in 2014:

Commissioning of the photoinjector Laser driver (10 ps). Mounting of the laser beam optical transportation system at a photoinjector. Startup and adjustment of the photogun electron beam emittance measurement system. Manufacture and research of the "holed" GaAs photocathodes.
Commissioning of the linear accelerator of electrons (third stage) with electron energy up to 100 MeV. Startup of the fourth stage modulator. Research of performances IR-radiation of an undulator.
Creation of the prototype of nondestructive laser control system with ray space stability < 50 mcm. Explosion welding of Nb + stainless steel by advanced technology, cryo/vacuum tests. Manufacture and tests of 1-section prototype of hige-purity Nb-cavity.
Optimization of allocation of linear collider elements and related engineering, scientific and social infrastruction in Dubna, Moscow region.
Low Energy Particle Storage Ring LEPTA: upgrade of the vacuum system of the complex, enhancement of positron storage efficiency and electron cooling of positrons. Performance of experiments on positron annihilation spectroscopy (PAS), design and construction of slow positron channel and experiment chamber for PAS.
