HiSPANoS (HiSPAlis Neutron Source) is the first accelerator-based neutron facility in Spain, installed at the Centro Nacional de Aceleradores (CNA), where different experiments have been performed related to nuclear astrophysics, detector characterization, electronic devices irradiation, imaging, etc. An upgrade of the neutron facility has been carried out recently, installing a pulsing system at the 3 MV tandem accelerator at CNA. Such system, composed by a chopper and buncher unit, can provide nanosecond proton and deuteron pulsed beams. A new experimental line dedicated to neutron time-of-flight (n-TOF) technique has been installed at the tandem accelerator. Proton and deuterium pulse width of 1 ns have been measured with a repetition rate in the range of 62.5 kHz to 2 MHz. The commissioning of the n-TOF line has consisted of the measurement of the neutron field generated by Li-7(p,n) reaction with proton energy of 1912 keV.
