Abstract : This supplement to an existing ONR grant was used to develop new experimental capabilities both to diagnose and manipulate single component positron plasmas and to study the electron positron plasma system. A technique was implemented using a CCD camera and phosphor screen to measure the magnetic field line integrated density distribution of single component positron and electron plasmas in the plane perpendicular to the field. The sensitivity is sufficient to make quantitative profile measurements on plasmas with as few as 10 positrons. This supplement was also used to build the apparatus for and carry out exploratory experiments to use a rotating electric field to compress single component positron and electron plasmas.
