The responses are considered in terms of the initial slope of the optical density D-exposure E curve, the value of E for D = 1, the saturation density D, and the number of grains rendered developable per incident electron. For high D/D, values, the forms of the experimental (0, E) relationships are found to depart from those expected if the mechanism of rendering developable a photographic grain were a simple single hit process, in a way that depends on the electron energy. The effect on the single hit relationship of the dependence of the exposure on the depth of electron penetration is considered, allowing a more complete inter- pretation of the shape of the (D, E) curves in terms of simple descriptions of electron-grain interactions. The high sensitivities of the nuclear and Schumann emulsions make feasible the direct recording at useful magnifications of electron images formed by low energy electrons.","PeriodicalId":16983,"journal":{"name":"Journal of Scientific Instruments","volume":"1 7","pages":"707-14"},"PeriodicalIF":0.0,"publicationDate":"1968-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1088/0022-3735/1/7/303","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"16778710","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}
