Aims of the programme

Nuclear Physics
  • Participate in the n-TOF program of nuclear data measurement at CERN and in the later analysis.
  • Participate in the DESPEC and NCAP / FAIR experiments.
  • Identify possible collaborations with European institutions on development of neutron detectors for technological applications (spent fuel containers, etc.)

Accelerators
  • Promote and strengthen R+D in accelerator physics and technologies at the UPC.
  • Carry out the design and construction of a 12 MeV compact race-track microtron of electrons for medical applications.
  • Participate in beam dynamics studies and design calculations for the future linear colliders.

    Total number of researchers: 6

    The two main objectives of this project are:

    1) Continuation of the experimental programme on neutron capture cross section measurements of minor actinides at the n_TOF facility at CERN, including the measurement of the most relevant capture cross sections for the nuclear waste transmutation.
    2) Construction of a He-3 neutron detector with almost 4π angular coverage and very high detection efficiency. This detector will be used to measure the probability of the neutron emission of key nuclei of interest for nuclear technology, nuclear astrophysics and nuclear structure.

Accelerators

  • Collaboration with the DRM group (Dosimetry and Medical Radiation Physics) at project PRIMO - Advanced tools for linac simulation. Ministerio de Economía y Competitividad ref. FIS2012-38480 (2013-2016)
  • 12 MeV race-track microtron. “Desarrollo del sistema ATRIO”. Fundación de Investigación Biomédica del Hospital Gregorio Marañón (2013 – 2014).

    This is a multidisciplinary and interdepartamental project of the UPC coordinated and managed from the INTE. Its final goal is construction of a compact electron accelerator of race-track microtron type with the output beam energy between 6 MeV and 12 MeV. The work includes conceptual and technical design calculations, definition of technical specifications, assembling and tests of the accelerator systems and, finally, the microtron commissioning. The tasks are carried out in collaboration with other departments of UPC, CIEMAT, Skobeltsyn Institute of Nuclear Physics (University of Moscow), and a few Spanish medical centers. Currently the project team is developing the RTM control system and power supply module. The rest of the machine systems has been already built and tested. In parallel, the work on definition of design specifications of ATRIO, a demo version of a system for positioning of the accelerator head by a robot, is underway.
  • CLIC Project of CERN. CLIC is a project of a future linear collider considered by the scientific community as a possible future facility for the research of fundamental interactions of matter. . In the framework of this project the group members participates in the research on the Final Focus System with both dedicated (traditional) and local chromaticity correction schemes. The lattice optics, luminosity and tuning procedure are among the issues addressed in these studies. Another activity within this project is the beam dynamic study and elaboration of a proposal of an emittance measurement line for the CLIC.
  • Participation in the CONECTA network (Coordinación Nacional Española para la Ciencia y Tecnología de Aceleradores de partículas).
  • Member of the JUAS (Joint Universities Accelerator School). Person in charge: Youri Koubychine.
