PPT-1 Holistic Cathode Design:

Structuring the cathode surface to cancel the space charge limit David H Dowell SLAC and Seattle A holistic cathode design using a contoured surface which shapes the applied fields enhancement to cancel the space charge limit and linearize the field is described. Thermionic Emission. Electrons flow in electron clouds in metals.. The electrons easily leave the surface of hot metals – as they gain enough energy from the heat to overcome the attraction of the nuclei.. The electrolysis of aqueous solutions. Aqueous. solutions are solutions in . water. .. Water is a very weak electrolyte. It ionises very slightly to give hydrogen ions and hydroxide ions.. H. 2. O. (l). Reference: . Glencoe Chemistry Chapter 20 . Electrochemical Cells. Today’s objectives: . Define anode, cathode, anion, cation, salt bridge/porous cup, electrolyte, and voltaic cell. Predict and write the half-reaction equation that occurs at each electrode in an electrochemical cell. Chapter 6 d. Assume that the plasma density falls exponentially from the orifice entrance to in 1 cm. What is the total electron current that can be emitted into the plasma? 3.
