During the high RF power part of the firing (the bright part), the Argon plasma exhaust can reach 1 Million degrees C.

[CleveSaville]

Why Ar, when most plasma engines use Xe with its lower ionization energy and higher mw?

[ytams1]

Cost. Argon (Ar) is cheap since it can be extracted from the atmospheres of the Earth and Mars simply by cooling the air. Xenon (Xe) is very expensive and there is a world shortage.

[amnesiai]

must be hot! what temps are at the exhaust?

[niiidar]

He just told you. 1 million degrees.
