Preparations for the last experiments under Task A, the Optimization of Electron Beam Precharger, proceeded. Six subtasks are specified: (1) installation of the particle charge-to-radius measurement system; (2) measurement of particle charge; (3) medium to heavy dust loading using hydrated alumina (HYDRAL); (4) medium to heavy dust loading using high resistivity fly ash; (5) construction of a power efficiency model; (6) economic assessment. Items 1 and 5 were emphasized this quarter. Item 5 is the first step of item 6. By way of preparations for new E-beam particle charging experiments, a dust feeder for medium to heavy loading was constructed and tested. This system is a combination of a mechanical dust feeder and a fluidized bed to deagglomerate the particles before injection. The vacuum system serving the electron beam source was overhauled, and the fail-safe circuitry was upgraded to assure trouble-free operation in the next series of experiments. The laser-based charge and size measurement system was moved into position for use with the electron beam precharger. As a first step towards an economic assessment of an electron beam precharger, the power consumption of various functions of electron beam prechargers is discussed and compared with that for an electrostatic precipitator. 18 figs., 3 tabs.
