These figures apply to '2 of tops', (posted 15 June 2010), and its postscripts 'a', 'b', & 'c' .

_

They show the, (further revised), interior surfaces of the high and low pressure chambers .

Also shown are the gas-contacting surface of the cathode, (a small red disk at the base of the 'coffee-filter' upper surface of the high pressure chamber),

and that of the anode, (a small blue ring on the bottom of the low pressure chamber) .

These electrodes are estimates, as their area would be reduced or enlarged slightly for assembly clearances and seals .

_

The port between the chambers is shown in close-up in the center figure of the second row .

Above this, the vortex would form .

This vortex is given additional rotational room, (from postscript b), by changing the curvature of the carbon dioxide, (or mix), input zone

to an open form, (related to the function 1/x), resembling a saucer in cross section .

_

The wall of the 'cup' or 'filter' appearing to rest on this saucer is a channel by which laser light can be directed at the vortex ;

and through which observations of the process can be made .

Observation, together with the channel's expanding profile, (towards center), allows the laser(s) to be aimed in real time, following changes as they occur .

In use, this channel would be sealed by an insert, (of glass or another material), transparent at the laser and observational frequencies used ;

(and by the insert's inner and outer gaskets) .

It is important to the effectiveness of the laser that the channel, (beyond its insert), not fill with carbon dioxide .

The tamping gas, (a noble gas lighter than carbon dioxide, and which does not absorb strongly the laser frequency used),

if not layered with the carbon dioxide in the main intake channel, could be introduced through ports in the laser channel wall .

_

The surfaces shown would exist within a larger containment and electrical insulation block, (not shown), which would be assembled from four sections :

the 'coffee-filter', into which the cathode would be plugged and secured ;

the high pressure zone between the outer surface of the 'cup' and the upper surface of the top 'saucer' ;

the port zone, between the lower surface of the top saucer and the upper surface of the bottom one ;

and the low pressure zone, into which the cathode ring, (together with the bottom peak), would be plugged and secured .

Braces, (also not shown), between the top and bottom surfaces of the saucers would allow the passage of gas to and from the chambers while holding their sections of the block apart .
