WebPhoton-ALP oscillations would cause features in the spectra of distant galaxies as well as gamma-ray bursts from core-collapse supernovae. Axion and ALP decay would also increase the opacity of the Universe for gamma rays. These signals will be searched for through novel comparisons of gamma-ray data and model predictions. WebThe study and development of such systems belongs to the broader scientific and technological field referred to as High Power Microwave (HPM).

Web10 apr. 2024 · Most research studies of microwaves and high voltage pulses have focused on energy savings in comminution, but little research has been done on their application of in ISR. In situ cryogenic fracturing has been used in the petroleum industry and may be a potential novel option for use for the in situ recovery of minerals in the mining industry. WebThe output microwave pulse of a resonant pulse com- pressor (RPC) can be subjected to compression once more and transformed into one of higher power and shorter pulsewidth. The process is the series compres- sion and it allows to increase output power in com- parison with the maximum power achieved by a singe cavity.

WebIn microwave pulse compression one limiting factor is the Q of the resonant cavity which is “filled” with energy from some lower power source, and then rapidly switched out at some much higher power. Of course, the pulse width of the output pulse is much less than the low-power charging time. This is consistent with energy conservation [5].
