전자빔 조사에 의한 방향성 전기강판의 철손 감소를 위한 소형 전자빔 조사장치 설계 = Design of a miniature electron beam irradiation apparatus for domain refining grain oriented electrical steel with electron beams

다국어 초록 (Multilingual Abstract)

A nonconstact technique for reducing the core loss of a grain oriented silicon steel has been developed by the use of mechanical scribing, Q-switched laser, plasma jet or electron beam irradiation.<br/>
Among these methods electron beam irradiation has advantages of domain refining without any deformation or damage of insulating film on the surface of a grain oriented SI- Fe.<br/>
Over the past years, this processing was performed in vaccum of 10-4 Torr or below causing the problem of high cost and difficulty of continuous works.<br/>
In this paper, a miniature electron permeable window through which electron beam energy 40-80keV and average current 0.1-2mA were obtained for electron beam Irradiating on air was designed and manufactured
