Development of basic cold-cathode materials and fabrication of test diodes
Abstract
The work accomplished resulted in the successful completion of all the established program milestones. Specifically these milestones include: (1) The development of cold-cathode processing techniques, which resulted in activation to emission levels of 90 micro A beam current, which corresponds to about 4 A/sq cm beam current density. (2) Development of cathode transfer and tube seal technology which resulted in three successful transfers and seals out of three tries. (3) Fabrication of a functional cold-cathode tube from which emission velocity distribution measurements were made. (4) Fabrication of a hot-cathode tube from which emission velocity distribution measurements were made. (5) Development of emission velocity measurement instrumentation and the completion of tests.
