TRIGA Mark II reactor   https://ric.ijs.si/en/opis-triga/ 

  • research nuclear reactor near Ljubljana, Slovenia
  • built in 1966 (General Atomics), reconstructed in 1991
  • power can be set between ~ 1 W and 250 kW
      → neutron flux scales with power
  • several irradiation channels

• neutron spectra in different irradiation channels

  • samples are inserted to the core through vertical channels from the reactor platform
    • Photo of the reactor platform. The The Arrow points to the top pf irradiation channel

    TIC channel (https://ric.ijs.si/en/triangular-channels-1-and-2/ )
    φmax= 1.5∙1012 neqcm-2s-1

  • core (under ~ 5 m of water)
    • Photo of the reactor core during operation taken from the platform (through 5 m of water) Blue light glowing from the core is Cherenkov radiation from charged particles traveling through the water.

    Channel F19 (https://ric.ijs.si/en/f19-channel/ )
    φmax= 1.5∙1012 neqcm-2s-1

    Central channel (https://ric.ijs.si/en/central-channel/)
    φmax= 6 .7∙1012 neqcm-2s-1

    Other irradiation facilities:

    •Dry chamber (thermal neutrons, regenerated fast neutrons) (https://ric.ijs.si/en/dry-chamber/ )

    •In-core off-mode irradiation with secondary radiation when reactor is off  ( no neutrons, TID only )
