    The 10 × 40-cm long pulse neutral beam source developed at Lawrence Berkeley Laboratory has been selected as the prototype for the design of the U. S. common long pulse source to be used on tokamak fusion test reactor (TFTR), Doublet-III, and mirror fusion test facility (MFTF-B). The long...

  • Inexpensive, automatic range-switching electrometer. Vanderschmidt, G. F. // Review of Scientific Instruments;Jul1990, Vol. 61 Issue 7, p1988 

    A simple circuit is described which implements automatic range switching for an electrometer. The circuit may be expanded to any number of ranges and provides dead-time delay following a range switch. The operator may override automatic operation and use the circuit in conventional manual mode.

    The rotor electrometer is a new instrument which we hope will make possible searches for rare fractionally charged impurities in very large quantities of matter. The ultimate goal of the project is to be able to measure the net charge of 10 mg samples of any material to an accuracy of 0.05 q[sub...

    Ion sources can be damaged by arcs between metallic components of the source if these arcs are permitted to last. The negative-biased low-work-function converter in a surface conversion negative ion source is especially susceptible to metal-arc breakdown damage. Here an electronic circuit for...

    A plasma cathode ion source has been developed to attain a long lifetime in oxygen-ion production. In this ion source, a plasma of a nonreactive gas serves as a cathode in place of a thermionic tungsten hot cathode used in the conventional Kaufman ion source. An anode ring with an annular slit...
