LINAC has detected first neutrons

On December 5, 2019, the first neutrons were detected in the NFS facility, which main part is the LINAC accelerator. First low intensity proton beam at 33 MeV was sent to the NFS Faraday Cup, the beam was pulsed at a frequency of 500kHz by using the fast beam selector. 

Neutrons were detected with a detector composed of a EJ309 liquid scintillator placed in the time-of-flight room.
