FANT is the acronym of Enhanced Thermal Neutron Source (Fuente Ampliada de Neutrones
Térmicos, in Spanish). This is a parallelepiped box of high-density polyethylene moderator
and an isotopic neutron source. The moderator has a cylindrical irradiation chamber where
a rather uniform thermal neutron flux is obtained. The FANT design was previously
optimized and the neutron spectra were estimated by Monte Carlo calculations with the
MCNP6. 1 code. To check the characteristics of the FANT thermal neutron field …

FANT is the acronym of Enhanced Thermal Neutron Source (Fuente Ampliada de Neutrones
Térmicos, in Spanish). The system is made of moderator material with a neutron source of
intensity 5.83±0.14 x106 s-1. Externally, FANT is a parallelepiped box of high-density
polyethylene (HDPE) with dimensions of 90 x 70cm2 base area and 76 cm height. Internally,
it has a cylindrical irradiation chamber with dimensions of 70 cm long x 32cm Ø. The
241AmBe neutron source is housed in the chamber, with a shadow cylinder placed between …
