 Microfocus X-ray tubes "Laboratory Synchrotron"
Breakthrough In Kumakhov
Polycapillary Optics:
Microfocus X-ray tubes "Laboratory Synchrotron"
After the IRO has created a new generation of
polycapillary x-ray lenses named Kumakhov integral lenses (KIL),
it was possible to develop microfocus X-ray tubes "Laboratory
Synchrotron"
|
|
This
new, microfocus x-ray tubes patented technology is based on sub-micron channels enabling
ultra-densely packed and extremely efficient compact lenses.
Such integral lenses allow obtaining an x-ray flux
at the lens outlet that is two orders higher compared to monolithic
x-ray lenses of mid generation (with (5?10) micron channel size).
|
Polycapillary lenses were for the first time
suggested by professor M.A. Kumakhov 20 years ago (M.A. Kumakhov,
Patent 1322888, 1984, see ‘The evolution of polycapillary optics” in
special issue of Proceedings SPIE V:4155: Kumakhov Optics and
Applications).
|
Since that time the technology has undergone
substantive changes.
The last new generation of Kumakhov integral lenses has no analogues
in the world, and this technology of microfocus x-ray tubes falls now into the Hi-Tech
category.
This achievement was noted by the Technology Achievement Award of
SPIE 2002 ( SPIE is a world major authoritative scientific
organization, which participation encompasses 70 countries ).
|
|
Today, based on a 10W x-ray tube, developed
in-house and combined with optics, we have created an x-ray tube source
producing quasi-parallel monochromatic flux of 1010 ~ 1011
photons/sec·mm2, which we have used in diffraction studies.
|
|
Such
flux compares well with that usually obtained at synchrotron stations
( See
Comparison Table ).
Hence, we have named this microfocus x-ray tube source a “Laboratory Synchrotron”.
|
At the same time, in contrast with the works
carried out at workstations in synchrotron centers where the
researchers are strictly limited in time and have other restrains, in
our case we provide for a freedom of creativity and the possibility of
careful and long term investigations.
|
It should be also taken into consideration
that our
microfocus x-ray tube "Laboratory
Synchrotron" has a
reasonable price and is affordable to a greater number of scientists,
engineers, research laboratories, universities, companies and so on.
|
|
Our
microfocus X-ray tube "Laboratory Synchrotron" is a portable instrument and does not need special premises,
radiation protection measures. In addition, it can be easily
incorporated in existent diffractometers, thus creating additional
advantages.
