Iron Plasma

Post by Pim Muller » Fri Mar 03, 2017 9:40 am

So two days ago we were determining some plasma characteristics using a languir probe and we were checking what effect an increase in current would have.

At one point we were roughly putting in 3kW in the device when the grid melted. The plasma which was glowing a nice blue very briefly changed to a more turquoise-green when the grid melted. Later when checking, iron does have spectral lines which look very much alike what we saw. We think that at the moment the grid melted some iron got evaporated and ionised resulting in the green glow.

Attached is a picture of the plasma before and at the moment of the grid melting.
