Lithium fluoride ion source experiments on PBFA II
- Sandia National Laboratories, Albuquerque, New Mexico 87185 (US)
Lithium fluoride, field-enhanced ion source experiments are being performed on PBFA II. The source consists of a thin coating of LiF on a microscopically rough substrate. Diagnostics to measure ion beam energy, purity, and transport include electrical monitors, Faraday cups, nuclear activation, ion pinhole camera, Rutherford magnetic spectrograph, and shadowbox aperture array. With PBFA II operating at three-quarters energy, the source has produced 16 TW of ion power and 550 kJ of ion energy with 70% diode efficiency. Over 26 kJ of lithium beam energy has been focused to the diode center axis with a peak energy density of about 1.3 kJ/cm{sup 2} . PICDIAG simulations of the lithium focus indicate the intrinsic source divergence is about 45 mrad with a 20-{mu}m-grade porous stainless-steel substrate.
