Title: John E Sadleir: Innovator in X-ray Technology and Magnetic Shielding
Introduction
John E Sadleir is a prominent inventor based in Washington, DC, known for his contributions to the fields of x-ray technology and magnetic shielding. With a total of 4 patents to his name, Sadleir has made significant advancements that enhance the functionality and efficiency of various devices.
Latest Patents
Sadleir's latest patents include a method of fabricating x-ray absorbers for low-energy x-ray spectroscopy. This innovative method involves forming low-energy x-ray absorbers on a semiconductor wafer, such as silicon. The process includes depositing a seed metal layer, like gold, on the wafer and patterning it into stem pads for electroplating. Stems are then electroplated from the seed pads through a mask, followed by the deposition of an absorber layer, preferably using e-beam evaporation. After patterning the absorbers, the mask material is removed through a solvent bath and critical point drying.
Another notable patent is the method and apparatus of implementing a magnetic shield flux sweeper. This invention focuses on protecting magnetically sensitive devices with a shield made from a non-superconducting metal or a lower transition temperature material. The method creates a spatially varying order parameter in the material, allowing it to become superconductive as the temperature decreases. This results in a flux-free Meissner state at the center, effectively sweeping magnetic flux lines to the periphery.
