  Laser-driven neutron sources are routinely produced by the interaction of
laser-accelerated protons with a converter. They present complementary
characteristics to those of conventional accelerator-based neutron sources
(e.g. short pulse durations, enabling novel applications like radiography). We
present here results from an experiment aimed at performing a global
characterization of the neutrons produced using the Titan laser at the Jupiter
Laser Facility (Livermore, USA), where protons were accelerated from 23 $\mu m$
thick plastic targets and directed onto a LiF converter to produce neutrons.
For this purpose, several diagnostics were used to measure these neutron
emissions, such as CR-39, activation foils, Time-of-Flight detectors and direct
measurement of $^{7}$Be residual activity in the LiF converters. The use of
these different, independently operating diagnostics enables comparison of the
various measurements performed to provide a robust characterization. These
measurements led to a neutron yield of $2.10^{9}$ neutrons per shot with a
modest angular dependence, close to that simulated.
