I had a hole drilled though the base plate and filled it with Argon Sussex NNC
We deposited soot from the carbon arc on an electron microscope slide and varied the Argon pressure
Sussex NNC Electron microscopy indicated that the structure of the deposited soot changed dramatically as the pressure was raised to over 80 microns
A manuscript of a paper presented at a conference in Capri sent to me by Mike Jura a professor of astrophysics at UCLA
