Google Patents US3928150A - Method of operating an electrolytic cell having hydrogen gas disengaging means This signal keeps a quartz oscillator in step with the resonance frequency of hydrogen, as shown in the figure.US3928150A - Method of operating an electrolytic cell having hydrogen gas disengaging means The result is a microwave signal that is locked to the resonance frequency of the hydrogen atom and that is continually emitted as long as new atoms are fed into the system. The tuned cavity around the bulb helps to redirect photons back into the system to keep the oscillation going. In this manner, a self-sustaining microwave field builds up in the bulb. These photons stimulate other atoms to drop their energy level, and they in turn release additional photons. Once inside the bulb, some atoms drop to a lower energy level, releasing photons of microwave frequency. The atoms that make it through the gate enter a storage bulb surrounded by a tuned, resonant cavity. Masers operate at the resonance frequency of the hydrogen atom, which is 1,420,405,752 Hz.Ī hydrogen maser works by sending hydrogen gas through a magnetic gate that only allows atoms in certain energy states to pass through. The word maser is an acronym that stands for microwave amplification by stimulated emission of radiation. The hydrogen maser is the most elaborate and expensive commercially available frequency standard. The carrier frequencies of 5, 10, and 15 MHz within this spectrum are internationally allocated for time and frequency radio broadcasts, and are used by a number of stations, including NIST radio stations WWV and WWVH. The area of the radio spectrum ranging from 3 to 30 MHz, commonly known as shortwave. The heterodyne technique is sometimes utilized to increase the resolution of time and frequency measurement systems, including the dual mixer time difference system, by converting the incoming signal from the device under test to a lower frequency. For example, a superheterodyne radio receiver converts any selected incoming radio frequency by heterodyne action to a common intermediate frequency (such as the 455 kHz frequency used by many AM radios). The abbreviation for hertz is Hz.Ī technique that generates new frequencies by mixing two or more signals together. The standard unit of frequency, equivalent to one event, or cycle per second.
