This paper explores the possibility of using microdischarges to generate broadband radio-frequency (RF) signaling from gas-based microdetectors of beta radiation. The concept is evaluated using two types of lithographically manufactured test structures: 1) a silicon/glass stack with etched detection cavities and 2) a planar metal-on-glass structure. The test structures include electrodes that bias...
This paper describes a miniature gas (Knudsen) pump that utilizes thermomolecular flow through a nanoporous membrane. A temperature gradient along the length of a pore that supports free molecular gas flow at atmospheric pressure pumps gas molecules from the cold end to the hot end. In contrast with past work, the membrane material is mixed cellulose which provides superior uniformity in pore diameter...
