HEAD | PREVIOUS | Chapter 1 Introduction 1.1 What is a Plasma? 1.1.1 An ionized gas A plasma is a gas in which an important fraction of the atoms is ionized, so that the electrons and ions are separately free. When does this ionization occur? When the temperature is hot enough. Balance between collisional ionization and recombination: | Figure 1.1: Ionization and Recombination Ionization has a threshold energy. Recombination has not but is much less probable. Threshold is ionization

A BLOOD ALCOHOL MEASUREMENT DEVICE USING A FIXED FREQUENCY PHOTOSPECTROMETER BY LUCILLE J. DURFEE ABSTRACT There are many people who go out for a night on the town without thinking about the potential dangers of drinking alcohol and then driving. A simple, non-invasive system is needed to test these people before they leave the bar to determine if they are “okay” to drive. The purpose of this project is to study, design ,build, and test a fixed frequency photospectrometer that will test the blood

Or how about a substance that has been used as a chemical warfare agent during World War I and the Iraq war? Well, each and every day many individuals are doing this very thing, only they have absolutely no idea they are consuming this toxic substance. In fact, this very same substance is claimed to

modeling. The general theme is that the current model of matter consisting of electrically neutral atoms composed of charged particles is integral to the understanding of electrical forces. The lesson begins with traditional activities of charging objects by friction and comparing electrostatic forces to magnetostatic forces. The traditional experiments are explained in terms of the model of an atom, and the “attract and repel force rules” are explored and expanded. Devices to create, store, and measure
