    Here is an example of a plasma originally used to observe the H3+ molecular ion.

    An uncooled plasma tube.

    A liquid-nitrogen-cooled plasma most efficiently used for carbocation spectroscopy named "E.T." The gas enters into the discharge region through 8 pairs of inlets that are constricted at the point of entry. Inlets of a pair face each other accross the plasma region so that jetlike streams from them meet at the center and cause fresh chemical reactions in the optical path.

    Here is the schematic of a general discharge tube without any cooling jacket. Different shells surround this based on the source of cooling: air, water, or liquid nitrogen

    "The Black Widow." Here is an example of an empty discharge tube that we are presently using.

    Here is Black Widow in action.
