PLASMA PHYSICS LABORATORY
In the laboratory,
both the high temperature plasmas and cold
plasmas are investigated. A Mather type Plasma
Focus device generates hot plasmas (temperature;
about 107 K). Different drivers to energize
the machine are:
i) A 9 ?F, capacitor bank
charged at 18 - 20 kV, discharge current up
to 200 kA.
ii) A 32 ?F, capacitor bank
charged at 12 kV, current up to 200 kA.
iii) A 12 ?F, capacitor bank
charged at 18 - 30 kV, discharge current up
to 300 kA.
Different experiments to enhance x-ray generation
efficiency and neutron yield are in progress.
The device is also used as ion beam (hydrogen,
helium, nitrogen, neon and argon etc.) source
for ion implantation of different materials.
The cold plasmas are generated by, 50 Hz AC
source, and a 13.56 MHz RF generator. For
the diagnostics, a one-meter monochromator
coupled with a computer carries Optical Emission
Spectroscopy. Langmuir probe is another diagnostic.
With different gases’ mixture plasma,
surface hardening of steel samples is investigated.
For the analysis of treated samples, micro
hardness tester and Raman Spectroscopy are
used. Both facilities are available in the
laboratory. In addition, X-ray diffraction
facility of GC University Lahore, and SEM/
EDX facility of University of Peshawar are
employed.
FUTURE INTERESTS
The research activities in
the laboratory are geared up towards plasma
processing of a variety of different materials.
A proto-type Plasma Ionitring Reactor is ready,
and efforts are underway for liaison with
the industry. |
