THE SECRET SOURCE

Fafnir Ion Plasma Source Gun Mythical Fafnir or Fire-Breathing Dragon

THE FAFNIR PLASMA SOURCE

FOR OPTICAL COATING


RUGGED and RELIABLE
Seldom needs maintenance, simple to operate, extremely stable operation. Will run for about 10 hours in oxygen before filament change, which is very easy.

POWERFUL and BROAD BEAM
Can operate continuously at 1500 watts of drive power. Over 60 degree cone angle, well suited for broad calottes and planetary part holders.

WELL SUPPORTED
This baby comes with the support of its Father.   The inventor (Ron Willey) is available for one free day of application assistance with each source, as long as his travel costs are covered.   Telephone and e-mail assistance are always available at no cost.   Source will function with a variety of power sources, but the "free day" offer only applies to users of an Advanced Eneregy MDX series power supply.

SPECIFICATIONS
Drive Volts: 50-600
Drive Amps: 0-10
Drive Watts: 0-1500
Dimensions: 160mm Dia. x 160mm high

TECHNICAL ADVANTAGES OF THE SOURCE:
This source resulted from my experiences with the Commonwealth Mk-II and Denton sources. It was specifically developed for high power in oxygen or other gasses. It is simpler, more rugged, and two to four times more powerful than the above mentioned sources. It will also operate at low powers if needed. It runs at lower voltages than the Denton sources for given gas flow/pressure. There are over 50 in the field now; one user has 20, and another user over 7 of them!

Specifics of the power supply requirements: We typically have used Advanced Energy MDX5 DC power supplies where the polarity is changed from minus to plus for the anode. An MDX15 has also been used. The source power limit is 1500 watts for continuous operation. An MDX5 is limited to 10 amps, so I was last running 10A at 60-150V (controlled by gas flow). A filament power supply is required at 20A, 50V max; AC or DC. A Variac will do just fine. A gas flow controller is also needed; at the low end it could be a needle valve.
