A brief description of the problems of bubble chamber optics is given, stressing the need to illuminate the chamber using Scotchlite on future large chambers. Experimental measurements of the contrast and widths of reconstructed track images are reported. Tolerances on the reference and reconstruction beam geometries and film flatness are given in relation to the measurement of bubble image positions to ± <strong>1</strong> μm in the hologram space. The formation of an image hologram minimises these tolerances and also permits the reconstruction stage to be carried out using a polychromatic extended source which could be useful for visual scanning of the track images.</p></div>","PeriodicalId":100989,"journal":{"name":"Optics Technology","volume":"2 3","pages":"Pages 132-138"},"PeriodicalIF":0.0,"publicationDate":"1970-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0374-3926(70)90036-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78194419","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}

Their experiments yield on explanation of generation of u.s.p. as radiation pulse passes through a 2-component medium. The pulses can be amplified but the increase in power is limited by atomic processes in the active medium. Possible ways of overcoming the problems are indicated, such as using one pulse passing several times through an amplification rod.
