A neutral beam injector system which produces 5 MW of 475 keV D/sup 0/ neutrals continuously on target has been designed. The beamline is intended to produce the sloshing ion distribution required in the end plug region of the conceptual MARS tandem mirror commercial reactor. The injector design utilizes the LBL self-extraction negative ion source and Transverse Field Focusing (TFF) accelerator to generate a long, ribbon ion beam. A laser photodetachment neutralizer strips over 90% of the negative ions. Magnetic and neutron shield designs are included to exclude the fringe fields of the end plug and provide low activation by the neutron flux from the target plasma. The use of a TFF accelerator and photodetachment neutralizer produces a total system electrical efficiency of about 63% for this design.

We have studied hadron production in e/sup +/e/sup -/ annihilation at 29 GeV center of mass energy. We have measured the particle fractions and particle separated differential cross sections using the PEP-4 (Time Projection Chamber) detector. The particles were identified by measuring their ionization energy loss (dE/dx). The pion fraction decreases from above 90% at 400 MeV/c to 55% at 6 GeV/c. Our results for kaon production require that a large number of kaons are produced by strange quarks pulled from the vacuum. We have also measured R, the ratio of the total hadronic cross section to the mu pair cross section. Our value for R is 3.7 with an uncertainty of 10%. This value is in agreement with the results of other experiments and with the predictions of the quark-parton model.

On August 5, 1983, President Reagan signed Public Law 98-67, which provides duty-free entry into the United States for certain Caribbean exports and allows U.S. business people to take tax deductions for the expense of attending conventions in the Caribbean region.

An experiment to search for quarks at the CBA is described. The cross sections for the production of massive quark-antiquark pairs in nucleon-nucleon interactions is estimated, and the experimental design and procedures are described. (WHK)

We describe the models used to calculate the equilibrium operating point for the MARS mode of the axicell MFTF-B, and present the model equations necessary to calculate the plasma and potential parameters in the central-cell, axicell, and anchor regions. In addition, we calculate the neutral beam, rf power, and gas inputs required to sustain the plasma and maintain the ion and electron-particle energy balance. After a brief description of the MFTF code, we present the results of a sample calculation using MFTF.
