Friends and Cyberneighbors!
The recent posting requesting information from users on their experience with
rotating anodes and the use of this information in evaluating which system to
purchase for a new lab prompts me to announce through this medium the fact that
Enraf-Nonius is now providing a NEW rotating anode system. The model FR591 was
displayed at the IUCr meeting in Beijing and we will be delivering the first
units in a few weeks.
The new system provides:-
1. High-frequency inverter technology for greatly increased efficiency
2. Greatly decreased size and weight
3. Available in either a high-brilliance or high-power version (9 or 18
KWatt, all models have full range of anode speed from 'idle' up to 6000
rpm and yes the 18 KWatt version can use the high brilliance focus
setting of the 9 KWatt version)
4. Full computer control with constant monitoring and dynamic adjustment
of anode speed, filament current, water flow etc etc.
5. A fully self contained system with an INTERNAL water-water heat
exchanger and no external HV tanks or vacuum pumps!
6. Very flexible geometry with two fully equipped X-ray ports.
7. Direct support from Enraf-Nonius who invented, designed and builds
More and more features of significant scientic value - talk to me
about the 10 micron vibration spec, the value of a decent electron optic
system, how direct pumping of the anode cavity improves vacuum and filament
life, what direct drive really does for you, etc etc.
As many people know Enraf-Nonius bought the rotating-anode line
previously marketed under the "Elliott" name by Marconi Avionics (a division of
the English "General Electric Company" in Dec of 1985. Various models of
rotating-anode generator had been sold prior to this time with model numbers
GX-6, GX-13, GX-18, GX-20 and GX-21. None of these were manufactured by EN
although we did sell some of them. Since the transfer we have offered parts
and service support for all customers.
The model FR571 RAG was the first built by EN and this model has been
continuously evolved by the redesign of major systems. The new model FR591
builds upon all of the previous developments and adds the high-frequency power
supply and computer control of a modern system. Note that this system is
invented, built, sold and serviced by Enraf-Nonius.
