Description
The new detection device for measurements of light ions (p, d, t, α) emitted as products of the
nuclear reactions induced by fast neutrons was recently developed at the Nuclear Physics Institute of
the Czech Academy of Sciences. The device consists of the vacuum chamber and rotational table with
the detection telescopes composed of two Si detectors for dE–E charged particle recognition. It is
coupled with the collimated beams of fast neutrons produced by an isochronous cyclotron U-120M
driven generator. The device can measure the double differential cross-sections with respect to the
angle of emitted light ions and to the incident neutron energy. The experimental data measured on
beams produced with the p(35 MeV)+Be(2.5mm) will be presented. The neutron field
characterizations by Proton-recoil-Method measured with the chamber will be shown and the
measured count rates will be compared with the estimations calculated by Geant4 simulations. In the
future, this new Chamber-for-Light-Ion-Detection (CLID) will produce new differential nuclear data of
high interest for the material applications related to the fusion and aerospace technologies and
potentially test and validate models of nuclear reactions themselves.
