Neutron wavelength estimation on crystal monochromator beamlines

- Abstract (Swedish)
- The world wide shortage of helium-3 is forcing the development
of new detectors for neutron spectroscopy. A candidate for
new detector design that consists of multiple detection volumes in
depth, in contrast to the traditional single volume helium-3 detector,
is being developed at ESS in Lund. One advantage of the
new design is the possibility of utilising the additional depth dimension
to extract information about the beams used in neutron
spectroscopy, more exactly their wavelength compositions.
The work done in this thesis aim to describe the beamline
compound with a prarametric probabilistic model. Parameter estimates
are obtained using a non-linear least squares regression
approach on both experimental and simulated data.... (More) - The world wide shortage of helium-3 is forcing the development

constructed using the parametric bootstrap.
