- The  crystal settings calculation in hkl now tried to put omega into
  the limts by calculating a delta omega.
- TRICS data files now include HKL and the UB
- The scan module has been expanded to support user defined scans which
  run a script at any scan point.
- A small fix to the PSD code in SinqHM_srv_filler

<H1>The Four Circle Diffractometer TRICS</H1>
<P>
<h2>Introduction</h2>
The four circle diffractometer TRICS is used for the study of crystal structures
The four circle diffractometer TRICS is used for the study of dynamic
and magentic structures
by neutron diffraction at single crystals. TRICS can be operated in two
modes: 1.) with a single counter very much like a traditional four circle
diffractometer and 2.) with three position sensitive detectors operating
like a oscillation camera as used by protein crystallographers. The second
option has not yet been implemented due to the unavailability of suitable
detectors and electronics. This manual describes the operation of TRICS
like a oscillation camera as used by protein crystallographers.
This manual describes the operation of TRICS
using the SICS software.

TRICS is situated at one of the beamlines for hot neutrons at the spallation
source SINQ at PSI, Switzerland. The incident beam first hits a
monochromator crystal. The selected wavelength is in principle fixed. A
TRICS is situated at one of the beamlines for thermal neutrons at the
spallation source SINQ at PSI, Switzerland. The incident white neutron
beam first hits a
monochromator crystal. The selected wavelength is not variable. A
monochromator lift with two monochromators and the possiblity to select
different reflections for diffraction at the monochromator however make it
different reflections peaks however make it
possible to select between a few different neutron wavelength. The sample is
held in a standard eulerian cradle with the usual angles omega, chi and phi.
Up to three position sensitive detectors are held on a detector holder at
different angles in two theta. Or a single detector is fixed to this setup.
Up to three position sensitive detectors are held on detector holders at
different angles in gamma and nu. Or a single detector is fixed to this setup.
The three position sensitive detectors may be moved up and down on a sphere
around the sample. This allows to access different lattice planes when the
eulerian cradle has been replaced by some cryostat or other sample
