My X-ray physics

Why am I so interested in the field of X-ray physics? Well, that's my job (except for computers) for looooong time already. I made made diploma thesis at Masaryk university and another at Universite J. Fourier. I wrote my PhD thesis (yes, I put a part of it on Internet too!) on X-ray Reflectivity From Planar And Structured Multilayers. Now I work at the X-ray group at Laboratory of Thin Films and Nanostructures at Masaryk University.

The list of my publications is available on the net too.

Internet sites full of X-rays

Main server for X-ray physics: with links to tables, synchrotron and neutron research facilities etc.
ESRF (Grenoble): The largest synchrotron is in the world (6 GeV)
LURE, Orsay (Paris): My lovely synchrotron in one big beautiful city.
Institut Laue-Langevin --- ILL, Grenoble: Who likes scattering, he surely knows that this largest neutron reactor for physical research is in Grenoble
Center for X-ray Lithography: University of Wisconsin, Madison
Center for X-ray optics (CXRO): Lawrence Berkeley National Laboratory (LBNL)

Useful free utilities

My freeware programs devoted to X-rays

are listed themselves a little bit below

Henke tables of the atomic structure factors

This is a DOS program.
Note: if you did not read the README (bad mistake, you know!) and you wonder why Henke wants to start always from C:\HENKE directory, then you can find useful the following script HENKE.BAT:

set HENKE=e:\physics\henke\
%HENKE%henke.exe %HENKE%henke.dat %HENKE%compound.dat

Some utilities useful for X-ray scientists

gnuplot: This is great freeware scientific program for plotting 2d and 3d graphs. Available for many many operating systems!
Xfig: Great program for making pictures (freeware, GPL). Works under X-Windows (Unix, OS/2).
TeX, LaTeX, AMSmath package for LaTeX: TeX is the best typesetting system for writing reports, formulae, letters... whatever your want. It is true WYSIWYG, because whatever you see on your graphical terminal, it will be printed exactly like that on any printer.
Hacking Origin and IDL: Are you getting figures as PostScript files created by Origin or IDL? You are not satisfied with something in them? Then look at the page that helps to correct them for publication.
Operating system IBM OS/2 Warp: This is my favourite operating system. Wonderful and very useful for any X-ray scientist.
Before starting any flamewar: software (=vapourware) from Microsoft can be run there too. There are some limitations due to M$'s market (=money) policy, but who need any new functionality of Word >6.0, for example?
Does the LaTeX2e version of Springer-Verlag packages exists?: Look at springer-ny and follow the links.
Does the LaTeX2e version of Physical Review packages exists?: Not as far as I know. You (you too!) should complain them that they are still asking authors to submit documents using unsupported, obsolete versions of the LaTeX software.
zimg: Converts matrix-like data files (supporting ESRF header files as well) into GIF images.

My freeware programs devoted to X-rays

xrdsl --- X-ray diffraction on superlattices
sf --- calculation of the Bragg angles, structure factors, susceptibilities
angles --- inter-planar angles and stereographic projection
abrefr --- calculations of the Bragg angles and refractive indices
pm3d --- program for rapid visualisation of 3d data, without any gridding artefacts even for non-rectangular data. Great for experiments (PSD, big mappings at synchrotron...)
unspec --- decomposition of spec files into scans (I use this very often in ESRF)
... some more things in queue ... wait tuned!

In ESRF and ILL, I worked with the spec program for experiment control; so I have some macros (like reciprocal space scanning, mapping). Also, I have unspec program that converts the terrible data file created by spec into ordinary data ASCII files and then easily draw your scans using e.g. gnuplot or Matlab or Origin or whatever you use. (By the way, the motor control and experiment programming of spec is excellent, but the graph plotting interface is the worst one I have ever seen --- look at tics positions, for instance. Also they should learn graph options from gnuplot.)
