Title: M John Kniffin: Innovator in Multi-Detector Dewar Technology
Introduction
M John Kniffin is a notable inventor based in Santa Ana, CA (US). He has made significant contributions to the field of detector technology, particularly through his innovative designs and patents. With a total of 2 patents, Kniffin has established himself as a key figure in the development of advanced detection systems.
Latest Patents
One of Kniffin's latest patents is the Multi-detector dewar, which consolidates active and passive detectors on a single coldfinger within a dewar. This innovation is made possible by interposing an electromagnetic interference shield between the detectors, which acts as a waveguide filter to block any interfering frequencies. The waveguide is formed by a pair of spaced interleaved shields, with one shield associated with the dewar envelope and externally grounded, while the other is linked to the coldfinger. Photons that penetrate through the waveguide are deflected to the outside of the dewar by a flanged narcissus shield surrounding the passive detector. The design also facilitates the alignment of the detectors and the assembly of the dewar by constructing the envelope in several generally cylindrical sections, with the lowermost section being shorter than the coldfinger. This innovative approach allows for the coldfinger and the lowermost envelope section to be fused to a metal mounting base prior to the final assembly of the dewar.
