Pakistan launches national fusion program
-Sabina Griffith
Fusion World
Realizing the importance of fusion and the worldwide effort in this regard, Pakistan has launched a National Tokamak Fusion Program to develop human resource and capacity building. Under this program, the Government of Pakistan plans to install a small tokamak (like HT-6M of Hefei , China ) along with various accessories and diagnostics so as to acquire the basic scientific knowledge and the technical know-how of the fusion technology.

Glass Spherical Tokamak (GLAST) is a small limiter based spherical tokamak with aninsulating vacuum vessel. Proposed major parameters are R= 15 cm, a= 9 cm, k=2,Ip=50kA, BT=0.4 T, tp=10ms,
and Teo= 400 eV.
The purpose of this experiment is tounderstand the consumption of ohmic flux by the plasma start-up and to identify themechanism responsible for current penetration during start-up phase of the tokamakdischarge.
Because of the compactness, flexibility, low operation costs GLAST maysignificantly contribute to the better understanding of phenomena in a wide range offields such as plasma confinement; plasma stability; plasma turbulence and its impacton local and global plasma parameters; processes at the plasma edge and plasma-wallinteraction; new methods of plasma profile and parameter control; development ofnovel plasma diagnostics etc.Macroscopic plasma instabilities are one of the key issues in Tokamak research.
Someinstability can lead to complete loss of plasma and some causes less dramaticeffects. Therefore it is important to keep the plasma stable so that smallperturbation from the equilibrium does not lead to a complete loss of confinement. Inthis work the plasma equilibrium is constructed using Grad–Shafranov equation andstability is determined from the change of potential energy using energy principalfor the GLAST geometry

GLAST[2] (GLAss Spherical Tokamak)[2], is a small spherical magnetic confinement tokamak fusion reactor installed at the National Center for Physics by the Pakistan Atomic Energy Commission (PAEC) in 2008, with close coordination and collaboration with China.[3] It is a Magnetic confinement fusion spherical tokamak with an insulating vacuum vessel. The reactor is primary use to conduct scientific studies and experiments on nuclear fusion power by consuming plasmas to identify the mechanism responsible for current penetration during start-up phase of the tokamak discharge.[4] The reactor was developed by the PAEC with the help of Chinese assistance, and offers research on control plasmas
