Object of research special form of glow
discharge with small anode. It is interesting
that in certain conditions (radius of needle, gas
pressure and discharge current) plasma localizes
on the end of the needle. The scale of
microplasma source tenths of millimeter. Experi
mental devices of three types were created,
initial investigations shown their workability
were carried out.

Research of integral and local properties of the
plasma air flow generated by the extra small
plasma generator
Air plasma flow generator was designed and
constructed. Power source of this device was
constructed as well. The methods of measurements
of integral and local characteristics of plasma
flow and initiating discharge, spectroscopic
investigations of plasma flow, spreading to
atmosphere were carried out. Chemical composition
of flow was measurement.

Aspirating counter ACAI-02-GDT. The
device for investigation of the charge
composition of air and air-plasma flows was based
on the discharge principle, that is for
simultaneous measurement of ions concentrations
with mobility higher or equal the ultimate one.
The device consists of an aspirating
chamber, power sources, a signal amplifier, a
digital voltmeter-oscillograph and a computer.
