About Me
My Ph.D. research
My Ph.D. dissertation included two parts (a) wavelength inclusive photon generation & absorption using ray-tracing within Silvaco cylindrical co-ordinate system to compute light output, and (b) flat-band generation for the hetero-junctions of an embedded AlGaAs Bragg reflector.
My Masters' Thesis
In the first picture you see a close-up of my test setup which I built (with the help of a machinist) consisting of copper sheet surrounding high voltage capacitors surrounding copper pipe forming a PFN (pulse forming network), attached to aqueous load of copper sulphate solution, the ceramic tube is the Back Lighted Thyratron which we were testing, on the lower right are regular thyratrons forming trigger circuits culminating in a crowbar circuit. The impedance was 2.2 Ohms and I ran it up to 50,000 V and 22,000 A.
In the second picture is the entire setup (single shot oscilloscope was in the screen room on the right) consisting of an oil filled tank to immerse the test setup and a variety of power supplies for trigger circuits, heaters, oil pumps etc.
I adjusted the gas pressure in the BLT (electrical control) and characterized the switching jitter as a function of the trigger voltage, trigger PFN impedance, shape and duration.
