First experiments with big uranium set-up KVINTA irradiated by deuterons

1) To have „simple set-up for benchmark studies of neutron production and transport simulation codes (for example MCNPX code).

2) Systematic of deuteron beams with energies higher then 1 GeV.

3) Measurement of neutrons and delayed neutrons during low intensive beam

4) Activation and track detectors

5) To obtain strong source of neutrons for transmutation tests

Main objectives:

Set-up: Natural uranium target: rods with Al cladding total weight 315 kg (500 kg) Sometimes lead box is used: bricks 1780 kg

First irradiation - 2009

First experiment with very low intensity of beam – delayed neutrons measurement, no activation detectors

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
