This does not, however, signal the end of research in semiconductor optoelectronics, but rather the opening of new and ultimately more widespread application of optoelectronic devices. New and powerful signal processing and data transmission functions will become possible by the marriage of optical and electronic functions on a single monolithic wafer. Applications will range from simple single channel integrated repeaters to repeaters with error correcting electronics and switching capabilities to complex distributed computer data bus networks capable of interconnecting dozens of the computers of the 1990's with a circulating data stream operating in excess of 100 Gigabits/sec.","PeriodicalId":180541,"journal":{"name":"1980 International Electron Devices Meeting","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128769629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The range of pulse-up while maintaining high efficiency can be greatly extended by changing magnetic field levels and applied voltages at the same time. Further improvement in pulse-up operation is made possible by depressed collector techniques.

This paper discusses its experimental performance with a short 40 nsec pulse forming network the results of a preliminary air breakdown study, and modifications to extend to a longer 250 nsec pulse width. In the short pulse mode the magnetron peak power levels are on the order 500 to 800 MW. The frequency of 3.24 GHz has been measured by gating the pulse and using a solid-state dispersive line. The large peak electric fieldE_{p} = 5 times 10^{4}V/cm, which this system generates (without resonant cavities), gives a unique capability to study microwave interaction and energy deposition in air breakdown plasma. The breakdown of air for pressures up to 100 Torr has been observed by monitoring the density of the resulting plasma and its light output. The plasma density at 10 Torr is approximately 100 nc; ncis the critical plasma density where the microwave frequency equals the plasma frequency. The pulse width of the HICM will be extended to 250 nsec with a new pulse forming network which allows the examination of the hydrodynamic breakdown effects. A particularly interesting feature of the magnetron modification for longer pulse operation is the use of a novel high-voltage insulator. A newly developed circular waveguide TEonmode coupler allows axial seperation of two lengths of the eight inch output waveguide inside a larger diameter tube. The result is an effective dc isolation with very efficient r.f. transmission.","PeriodicalId":180541,"journal":{"name":"1980 International Electron Devices Meeting","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116884887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A series of computer models of the gun anode region were used to determine selected thermal and structural characteristics. Their effects on electron beam energy, velocity spread, and temperature were evaluate. The Thermal analysis yielded the steady state temperatures of 137 node points. Thermally induced mechanical expansions were found to be 0.20% axially and 0.82% radially. In the three dimensional coordinate sytem utilized, the stress in 373 elements were numerically evaluated. The cathode heater power brought the cathode emitter up to 1068°C in 500 seconds. The cathode cooling due to electron emission was found to increase the steady state heater input power requirement by 11% (for an emitter temperature of 1068°C) from 9 W to 11 W. The electron trajectory analysis included an evaluation of the beam energy, velocity spread, and temperature. The effect of the deformed mechanical shapes on the beam paremeters was determined.
