Torr
Scientific offer
a professional coating service for x-ray anodes used on all the major
surface analysis instruments,
…………….which
is also fast and competitively priced !
We
can coat both twin and monochromator anodes used on VG, Kratos, VSW,
Leybold etc. instruments, using the usual materials Mg, Al, plus the more
exotic such as Zirconium, Yttrium, Titanium, etc.
All
work is conducted to the highest standards in an ISO 9000 approved company
by people who have a strong background in surface analysis related
instrumentation, and therefore understand the issues of cleanliness and
contamination.
We
use the latest sputter coating technologies to produce clean pure,
strongly adhering coatings, which are very rugged.
We
offer several different levels of service
-
a
simple clean and recoat (to specified thickness) with Mg, Al etc.
-
a
more specialist recoat including a proprietary barrier layer for more
recent instruments using higher powered / stressed anodes,
-
or
simply for older instruments to enhance anode lifetime
-
to a full
re-tip, cathode replacement and re-build

*Note:-
All prices quoted are FOB TSL.
1.
with
twin anodes cross contamination of anode material is guaranteed to be less
than 0.1% - but the electron optics of some anodes is such as to result in
greater apparent cross-talk.
2.
with
Mg anodes every effort is made to minimise ghosts due to Oka,
but this will be function of the time the surface spends exposed to air;
for this reason we recommend the use of inert gas filled shipping tubes
(which we can provide at additional cost). Also the ghost intensity will
be a function of the Al window thickness since it preferentially filters
the softer Ok a.
3.
Other
permutations of anode material Al / Mg / Zr / Y / Ti are available on
request.
4.
Barrier layers
prevent lower melting point Al/Cu / Mg/Cu etc eutectics forming which
limit power / lifetime. Such layers are essential for many modern anodes
as they are integral to the design
5.
A
full rebuild will be coated for on an individual basis
