Introduction 2. Big uranium target KVINTA 2.1 Description 2.2 First set of experiments 2.3 Beam monitoring • 3. ERINDA project • 3.1 Project of 7 FP • 3.2 Cross-section measurements • 4. Conclusions and outlooks

  2. "Центр Физико-Технических Проектов“ "АТОМЭНЕРГОМАШ" KVINTA Setup Set-up:Natural uranium target: rods with Al cladding total weight 315 kg (500 kg) Sometimes lead box is used: bricks 1780 kg Main objectives: • To have „simple set-up for benchmark studies of neutron production and transport simulation codes (for example MCNPX code). • Systematic of deuteron beams with energies higher then 1 GeV. • Measurement of neutrons and delayed neutrons during low intensive beam • Activation and track detectors • To obtain strong source of neutrons for transmutation tests

  3. Detector plates Target «Quinta-М» Pad with a Pb foil monitor and SSNTD Plate (700х400х16) Platform Beam window Rails p, d - SSNTD and AD positions at the QUINTA-M target surface QUINTA-M setup layout at the irradiation position

  4. Detectors plate Cadmium containers with activation detectors R=40 Track detectors R=120 Installation of KVINTA set-up and placement of detectors

  7. First irradiation - 2009 First experiment with very low intensity of beam – delayed neutrons measurement, no activation detectors

  8. First full irradiation – March 2011 Three different energies: 2 GeV, 4 GeV and 6 GeV – low and high intensity run irradiation time – around 20 hours

  9. Aluminum and copper beam monitor foils Deuteron beam 2 GeV, 4 GeV and 6 GeV Integral number of deuterons – aluminum foil few meters from the set-up Common measurement using ionization chamber Common measurement of copper foil cross-section determination 8 cm Cut copper foil – beam profile determination

  10. ERINDATransnational Access Activities The ERINDA project is an Integrated Infrastructure Initiative (I3) funded under the 7th framework programme (FP7) of the European Commission. The ERINDA Project Start date: 1/1/2011 Duration : 4 years Beam time: 2600 hours Typical experiments: 26 Support: 80 manweeks The ERINDA Consortium 13 partners- 13 facilities hours for external users Web-site: www.erinda.org Project Coordinator: A. Junghans

  11. Main ERINDA tasks → measurement capabilities : quasi-monochromatic neutron beams high-resolution neutron time-of-flight facilities thermal neutron beams charged particle beams indirect measurements (surrogate reactions)isotopic yield distributions (Penning trap) → neutron energy range: sub-thermal energies – several hundred MeV February 21, 2011 high-quality nuclear data for waste transmutation or Generation IV systems

  13. Accelerator – Cyclotron U-120M • Different tasks: • Radiopharmaceutical research and production • Astrophysical reaction research (mainly with 3He beam) • Neutron research using two different neutron generators Beam: protons with energy from 10 up to 24 MeV (3μA) deuterons with energy from 10 up to 20 MeV (3μA) 3He with energy from 17 up to 57 MeV (2μA) alpha with energy from 20 up to 40 MeV (2μA) High intensive 1011 cm-2s-1negative ion beam: protons with energy from 10 up to 37 MeV (20μA) deuterons with energy from 10 up to 20 MeV (10μA)
