They were 6-cavity, frequency-tunable klystrons which could deliver 1 MW continuous output power for 10 s duration. Each klystron has a similar electron gun with a modulation anode, and an evaporation-cooled collector.A prototype klystron was tested for 1 MW performance successfully and a two-window version was also manufactured in order to reduce the thermal stress of the window material. A high-power magic tee was used in order to combine the two power outputs and to produce more than the 1 MW power output. The window temperature was observed to rise, with light emission. The measured temperature rise was about 16°C at the end of 10 s duration, when the klystron was operated at the power level of 500 kW per window.An external digital computer was used to control the high-speed tuning mechanism several times during every one pulse operation.","PeriodicalId":76653,"journal":{"name":"The Journal of microwave power","volume":"26 1","pages":"173-179"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83289813","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}

Such prototype applicators have been used with a number of industrial materials to assess the feasibility of drying or heating with radio frequency power. Essentially, two aspects are considered in this paper. Firstly, with the prototype applicators not coupled to an oscillatory (tank) circuit of a radio frequency source, the resonance characteristics and Q-factors are measured leading to the establishment of the utilisation efficiency. Secondly, the interaction at lower power between the loaded applicator and the tank oscillatory circuit which is coupled to it, is considered in terms of the return loss and the impedance loci. A critical electrode separation, dc, is observed which is dependent on the material loading and at which the impedance loci and return losses of the loaded applicator and tank oscillatory circuits are identical. Such an observation may be a...","PeriodicalId":76653,"journal":{"name":"The Journal of microwave power","volume":"1 3","pages":"197-216"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/16070658.1985.11720305","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72453902","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}

Following the irradiation period, various insect development parameters were monitored until the next generation was produced. Microwaves did not have any influence on food consumption of the larvae, but larval weight, mortality and the rate of development during the successive larval stages were affected. There was no occurrence of deformities. No effect could be detected on pupal development, sex ratio and mortality.
