  1. Saint-PetersburgPNPI Welcome V. F. Ezhov PSTP 2011 12-16 September

  2. Gatchina, located 45 km south of St. Petersburg, former residence of Russian emperors

  3. PNPI research directions: • physics of elementary particles and fundamental interactions; • physics of atomic nuclei and nuclear reactions; • neutron physics; • solid state physics; • theoretical physics; • physics and engineering of reactors and accelerators; • molecular and radiation biophysics; • radiation medicine; • new techniques and experimental equipment PNPI base facilities: • 18 МW research nuclear reactor; • 100 МWresearch nuclear reactor (to be completed in 2013); • 1 GeV proton accelerator.

  4. Petersburg Nuclear Physics Institute of RAS PIK PNPI ПИЯФ Accelerator International Neutron Research Centre (Project) 1 GeV protonaccelerator WWR-M reactor PIK reactor

  5. Polarized neutrons • Polarized He-3 target - neutron polarizer • Magnetic resonance – EDM of neutron • Magnetic trap – UCN neutron lifetime

  6. Status of EDMexperiment in PNPI Experimental scheme used in PNPI Modernized PNPI EDM spectrometer PNPI – ILL collaboration Waited accuracy

  7. Atomic Magnetic moment in inhomogeneos magnetic field.1922 – Stern and Gerlach

  8. Vladimirskii, V.V. Magnetic Mirrors, channels and bottles neutrons. Sov. Phys. JETP 12, 740-746, (1961)

  9. The main problems: 1. Filling and empting. If one use superconducting system, then he can’t switch on field too fast. 2. Huge setup and small storage volume =87710 s

  10. Neutron lifetime Last results Magnetic trap Gravitational trap Expected accuracy of new projects

  11. Thank you for attention&Welcome to PNPI

  12. Cosmology and Particle Physics & Neutron Experiments • CP-violation - dominance of matter over antimatter • Baryogenesis • Fundamental interaction - Standard Model, Supersymmetry… • Stellar Nucleosynthesis • Mirror Universes • Gravitational vs inertial mass • New forces & Search for Dark matter candidates • Search for Neutron Electric Dipole Moment (EDMn) • Neutron lifetime • Neutron lifetime; Correlation coefficients in neutron decay; EDMn • Neutron lifetime • Neutron - mirrorneutron oscillations • Neutron diffraction in perfect crystals • Experiments with ultracold neutrons (UCN)
