[NOBUGS] McXtrace 1.4 released!

[Erik B Knudsen]

On behalf of the McXtrace Team I am happy to announce that we have at
last released McXtrace 1.4.

Below is a list of some of the changes and edits sinece the very old 1.2
version.

Please head over to www.mcxtrace.org and grab a copy - or simply update
through the usual software repositories as applicable.

CHANGES in 1.4

1. Source_pt, Source_flat, Source_gaussian, and Source_div now behave in
the same manner wrt. phase. The relevant parameters
are randomphase and phase. If randomphase is !=0 the phase is completely
random, if ==0 the value of phase is used.
2. EPSD_monitor: Has a parameter nE which denotes a number of energy
bins. if >1 the monitor will output a number of files
each corresponding to an energy bin.
3. Lens_parab, Lens_parab_Cyl The functionality of the _rough versions
of these components have been merged into the main components
and the _rough versions themselves retired.
4. Support for binary file dump of photons in the mcpl-format is added.
5. On debian class systems, McXtrace now installs to /usr/share to be
more standards compliant.
6. New Components:
    sources/Undulator.comp: Undulator model based on Kim, 1989,
“Characteristics of synchrotron radiation”

    samples/Incoherent.comp: Model sample of an incoherent scatterer
    samples/Polycrystal.comp: Polycrystal sample based on Single_crystal
formalism
    samples/SasView_model.comp: All samples included in the SasModels
module of SasView.
    	Currently does not take in absorption into account

    misc/Air.comp: A “box” full of Air that may scatter-
    misc/Focus.comp: Adds resampling to any component. I.e. causes the
preceding object to become a secondary source.
    misc/MCPL_input.comp: Interface components to read/write MCPL-format
files.
    misc/MCPL_output.comp

    monitors/DivE_monitor.comp
    monitors/DivPos_monitor.comp
    monitors/Divergence_monitor.comp

    optics/Bragg_crystal.comp: Superseeds Perfect_Crystal
    optics/Bragg_crystal_bent.comp: Bent crystal model
    optics/Capillary.comp: Capillary tube with reflecting walls.

    optics/Collimator_linear.comp: Ideal collimator models
    optics/Collimator_radial.comp
    optics/Mirror.comp: Simple flat mirror component
    optics/Mirror_toroid.comp: Toroidal mirror

    contrib/Detector_pn.comp: Detector model with quantum efficiency.
    contrib/SAXS/SAXSCurve.comp: A set of SAXS-sample models
    contrib/SAXS/SAXSCylinders.comp
    contrib/SAXS/SAXSEllipticCylinders.comp
    contrib/SAXS/SAXSLiposomes.comp
    contrib/SAXS/SAXSNanodiscsFast.comp
    contrib/SAXS/SAXSNanodiscsWithTagsFast.comp
    contrib/SAXS/SAXSNanodiscsWithTags.comp
    contrib/SAXS/SAXSNanodiscs.comp
    contrib/SAXS/SAXSPDBFast.comp
    contrib/SAXS/SAXSPDB.comp
    contrib/SAXS/SAXSQMonitor.comp
    contrib/SAXS/SAXSShells.comp
    contrib/SAXS/SAXSSpheres.comp

7. Example Instrument simulations:
  - Full model of proposed DanMAX beamline
  - Pump_probe_solvent: Example of disordered scattering in solution
  - SAXS_saxlab: Laboratory SAXS setup with Montel optic
  - template_1Slit_Diff & template_2Slit_Diff: examples of raytracing
with coherent interference effects.
  - ESRF_ID01: Microdiffraction beamline with polycrystal sample
  - templateSasView: Example of using the (experimental) SasView interface
  ... and various Unit test/Example instruments

8. New python/Qt based GUI/plotting tool
9. PowderN: incoherent scattering (computed from tables)
10. Curved Bragg monochromator crystal
    Major improvements to the flat Bragg monochromator crystal
11. Output in the NeXus-format.
12. Data files can be read only once and reused by other components.


Happy simulating!
