  In this paper, we report on a tabletop experiment studying neutron scattering
in a Spherical Proportional Counter using an Am-Be source. Systematic studies
were carried out to investigate the effect of gas mixture, pressure, operating
voltage, and sphere size on the drift time-rise time relationship of the signal
in a spherical proportional counter. Our experimental results showed good
agreement with MagBoltz simulations. These findings are a crucial step towards
measuring the quenching factor in gases using a neutron beam for the New
Experiments With Spheres-Gas (NEWS-G) experiment and has important implications
for the development of neutron detection techniques and their potential
applications in nuclear and particle physics.
