PowderN. Can be thought of as a large number of crystals,
each scattering neutron rays according to Braggs law, thereby
producing N concentric Debye Scherrer cones. This sample also
has the posibility of adding inchoherent, eleastically scattered
Monitors Objects monitoring or registering neutron ray
characteristics. In the exercises below are used different types
of detectors or monitors:
Monitor. Single monitor, detecting the number of neutrons flying
through a plane. (User defined opening size).
PSD_monitor. Square monitor, detecting the number of
neutron rays passing through a plane, divided into
pixels. Square regions of a plane. (User defined resolution
and opening size).
PSD_monitor_4PI. As PSD_monitor but shaped like a sphere.
L_monitor. Wavelength monitor, measuring the different
wavelengths of the passing neutron rays. (L is for ).
Monitor_nD. General monitor for detecting all sorts of
physical properties of the neutron ray. In our cases used with
'single' - as PSD_monitor but only one small square.
'banana' - as PSD_monitor but shaped like a curved,
Collimators Devices controling the direction and divergence
of the neutron ray.
Collimator_linear A series of parallel absorbing neutron plates
that limits the beam divergence.
Typical values are to .
