Radio frequency inductively coupled plasma sources are widely used in low temperature industrial processing. Recent computer simulations and experiments indicate significant improvement in processing results with the use of pulsed plasmas. This thesis reports simultaneous measurements of nearly all plasma and electromagnetic properties of an ICP in three-dimensions under pulsed operation.The plasma density profile is measured by rf compensated Langmuir probes, hairpin probes, and a 60 GHz microwave interferometer. Line integrated electron density measured from these three very distinct diagnostic techniques (interferometer, Langmuir probe, Hairpin resonator probe) shows agreement. Three-axis Bdot probes are used to measure the magnetic field. Inductive plasma current is calculated from measured magnetic field using Ampere’s law. With the observed cylindrical symmetry, the electromagnetic electric field is derived from Bdot data using Faraday's law. The above field and current are used to calculate the inductive power and Poynting vector. A side by side comparison in pulsed plasma operation is presented for two industry-relevant neutral pressures (5 mTorr, 25 mTorr). Distinct plasma evolution is observed with the two cases. The observations from the experiment are explained with the help of a simple lumped element circuit model.

This is a tabletop game. 

The object of this game is to perform four different levels of concerts successfully. There are four difficulty levels: simple, medium, difficult and challenging. You are a high school student, full of passion in music. You and your fellows start a music band, based in your school. Throughout the school years, you and your fellows will improve skills, recruit new members, and participate in concerts. Earn your band fame and funds for each successful show performed. Progress to next level of stages as your band grows and becomes the best school band in the world. Will you lead your band to Wiener Musikverein?
