Measurement of the quenching factor of Na recoils in NaI(Tl)

Chagani, H., Majewski, P., Daw, E. J. et al.

Understand

Measurements of the quenching factor for sodium recoils in a 5 cm diameter NaI(Tl) crystal at room temperature have been made at a dedicated neutron facility at the University of Sheffield.

  • The crystal has been exposed to 2.45 MeV mono-energetic neutrons generated by a Sodern GENIE 16 neutron generator, yielding nuclear recoils of energies between 10 and 100 keVnr.
  • A cylindrical BC501A detector has been used to tag neutrons that scatter off sodium nuclei in the crystal.
  • Cuts on pulse shape and time of flight have been performed on pulses recorded by an Acqiris DC265 digitiser with a 2 ns sampling time.
