Query: Measurements of the neutron absorption in supermirror coatings   In this work we report on measurements of neutron absorption in supermirror
coatings. The measurements were carried out using the SuperADAM instrument at
the Institut Laue-Langevin and by measuring the gamma-ray production from m = 3
and m = 4 neutron supermirrors when illuminated by a beam of neutrons. The
results provide a valuable validation for recent computational and theoretical
work that can be used as input to Monte-Carlo radiation transport calculations
for the design of the shielding of neutron scattering instruments.
