This story goes back to 1981, when I had completed my Masters in Physics from Delhi University and was proceeding to USA to do PhD. I did specialization in Astrophysics and General Theory of Relativity during my MSc. During summer of 1981, I had worked with Prof J V Narlikar on Black Holes at TIFR as part of NCERT National Science Talent Search Summer Camp.
This long blog describes my successful foray into experiments to prove my model and my insistence on using only components available in the local market. It led to a unique development, improvement of machine to international standards and publication in top rated journal in spite of efforts made by colleagues to put barriers!
During 1995-96, while trying to run ADITYA Tokamak (Nuclear Fusion Reactor), we used to find that nearly 80% of the discharges fail to go through. This was due to the fact that power supply control system used to stop the discharge due to some malfunctions. ADITYA power supply system was controlled by a PDP-11 computer. It was popularly believed that software in the computer has some problems due to which the control system was malfunctioning. This was frustrating as lot of effort went into running the machine but there was very little output.
(For those, not aware, Tokamak is a device used to confine very high temperature plasma to produce energy using controlled nuclear fusion. As of now these are not in commercial use but at research stage. But we are getting close, like we have been saying for last 60 years !!!)
When SINP Tokamak installation was going on, Japanese Engineers from Toshiba came to install the machine as it was manufactured by Toshiba in Japan.
