[3dem] Solarus H2 only

[Schwartz, Cindi (NIH/NIAID) [E]]

Hi there,

We're trying to set up our Solarus 950 to do a H2 only plasma on graphene grids.

We have tried many, many permutations, but are unable to generate plasma with H2 only. In fact, at this point, we realize that our O2:H2 program is probably actually O2 only.


  1.  O2 only has plasma
  2.  H2 only does not have plasma
  3.  We move the O2 line to the H2 input in the back of the machine, we get plasma
  4.  We move the H2 line to the O2 input and we do not get plasma
  5.  We have the line unattached to the machine and we can get H2 gas coming out of the line
  6.  We have tried maxing the allowable sccm for H2 and no plasma
  7.  We have not tried adjusting the wattage, which default is 50 W

If you have a working program, can you please share? Or any other thoughts?

Thanks,

Cindi L. Schwartz
