I have got a fluorescent tube to light in the inductor coil of a Hartley
oscillator at 2.645MHz.

Do I have plasma?

Hello!

Currently I'm simulate the plasma cloud expansion using my 3D hybrid
PIC code.

Model description and some results of my code are available at
http://comphys.narod.ru/3d_cloud_v3.htm.

The simulation results are reasonable in general.
But some contraversal results http://comphys.narod.ru/m20d14.htm
turn out in case of the Ma > 10/
Especially suspicious things occur on a equatorial plane:
http://comphys.narod.ru/m20d14.htm#CloudVelocityXY
http://comphys.narod.ru/m20d14.htm#MF_XY
where the spatial anisotropy of cloud expansion is observed

Couldn't you help me to understand the reasons of such discrete
anisotropy?

I have a coaxial dielectric barrier discharge cell operating in air at
atmospheric pressure.

The construction (from the inside, out):
Inner electrode: Stainless steel, 19 mm diameter
Inner air gap: 1 mm width
Dielectric: Borosilicate glass, 1 mm width
Outer air gap: 1 mm width
Outer electrode: Stainless steel, 25 mm diameter

Cell length: 10 cm

When I apply pulsed AC to the cell I see 100-500 mA (12 ns) current spikes
with cell voltages of 600-800 volts.

Is 800 V a reasonable discharge voltage for this cell? Or should I suspect
my test configuration?

available at comphys.narod.ru

Can you make plasma using a coil with a tube of low pressure hydrogen gas
inside? If so can someone give me details or point to a book that gives full
details for making a plasma like that.

Hello,
Maybe someone is interested in reading and eventually makes comments
on some free materials (atomic structure, relativity, gravitation,
electromagnetism) at following link: www.elkadot.com.
The free materials are excerpts from books and show another face of
physics.

Hi Group,

I need to construct a plasma chamber for oxygen or hydrogen plasma
etching process. I have to coat the copper electrode and inner wall of
the chamber. I know that painting by carbon works fine. I was wandering
is there any better coating methods + materials for this purpose, where
the coating is more stable and sustain longer? Any advice would be very
much appreciated!

Best regards
