An Examination of Technological Advancements and Innovations of Horn Mouthpieces in the United States from 1950 to 2015
(2021-05-05)Before the invention of numerical control, also known as Computer Numerical Control, or CNC, horn mouthpieces were handmade; this made every horn mouthpiece very unique due to the inconsistencies in the handmade process. ... -
An experimental apparatus and diagnostics for the study of vacuum surface flashover
(2022-05)Upper operational limits in pulsed power vacuum systems are typically determined by the maximum electrical stress the apparatus can handle. If this limit is exceeded, the first point in these systems to fail is usually the ... -
The sensitivity of PBX 9501 and PBX 9502 to milling and sawing
(2022-05)Explosive driven pulsed power research benefits from modern polymer-bonded high explosives (HE). In practical application, high precision in the dimensional shape is required, and high machining speeds are desired. The ... -
Two-color pyrometer measurement of stainless steels due to relativistic electron beam heating in VHV/UHV environments
(2022-05)Temperature measurement of SS anodes is of particular importance for Sandia National Laboratories. This is because the theory of SS anode outgassing is thought to be a function of temperature increase. To investigate the ... -
