A magnetic dipole can be made by running a current through a loop of wire. Most permanent magnets are bar magnets, however, and these are still commonly referred to as producing a dipole field. In this topic we will examine a very simple case in which the magnetization of a cylinder is used to determine […]

A typical graduate student’s desk is shown in figure 1. While appearing as an unorganized cluster of paperwork and beverages, the items shown actually represent a finely tuned operation of study and productivity. The interplay of all these objects is described after the labeled image of figure 2. In figure 2 the contents of figure […]

Various exercises with an electron beam are performed as part of the undergraduate plasma laboratory at UCLA. This course (look up PHYS 180E at the UCLA Physics and Astronomy Dept.) is intended to introduce upper division undergraduates to experimental plasma physics. While acting as the TA for the course during the Spring 2006 quarter I […]

While working in an undergraduate plasma laboratory I had the opportunity to use an old device for recording data. The XY recorder is to data collection as the typewriter is to a computer. An ink pen is attached to a rail that moves according to input signals. The recorded takes a voltage input for both […]

Update: An object oriented version of this routine, one that uses iContour, is now available as conmakeOBJ. Details Filename: conmake.txt (Contour Make) Direct Download: conmake NOTE: the download is provided as a .txt format, but the file must be renamed with a .pro extension (i.e. conmake.pro) before using.

Introduction This is a summary of the construction procedure for a triple probe (four tipped Langmuir probe) to be used in the LAPD. All of the dimensional requirements presented are taken from an internal lab document, which is not cited for each individual instance at which it is referenced. While many of the details contained […]
