RESEARCH FACILITIES
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.
