What ISM(HiFer) allocations are really for.
 

I had a chance last night to see this baby in action.

Pretty good screen room, I couldn't pick it up in the parking lot on my
DX398.

Of course the discription;"G1 13.56MHz RF Generator delivers up to 3000
Watts into a 50-W , non-reactive load. It uses a 3 phase, 208 Vac,
50/60 Hz power source, is water-cooled, and provides control signals
through a 25-pin analog/digital user port." is misleading. Under
typical use
only 50W are needed. Much more power is there if needed.

"...50-W, non-reactive load."

In this context, "W" means "ohms". (why not just say ohms? I have no
idea)

That doesn't necessarily mean that application requires more than 50
watts of power, but you can't tell from what's on that page.

The maximum this machine had ever used was around 30W.

A very contained field.

Somehow when I took Physics I never thought anyone would want to
"implant ions".

Typo and/or bad font conversion, I suspect. The letter omega of the
opposite case from the one we use (I don't remember if it's upper or
lower) looks like a "w", only rounded. It's used in physics for
angular velocity.

Wow. Interesting and strange.
A company I worked for many years ago was
doing ion implantation of semiconductors.
I didn't realize that so much HF power was
involved.

The strange part is that that info is hosted by
a company that makes shipping cases. ?
