This paper utilizes FLUKA code to evaluate the electron beam-wastewater interaction effects with different energy, space and divergence distributions of the electron beam. With 8 MeV average energy, the electron beam exits from a 0.0127 cm thick titanium window, travels through a 4.3 cm distance in air and through a second 0.0127 cm thick stainless sample container window with 2.43 cm radius, and finally is injected into the wastewater sample container, which has a volume of around 75 cubic cm. The distributions of the electron beam are obtained from the GPT (General Particle Tracer) simulations for the UITF (Upgraded Injector Test Facility) in Jefferson lab. By varying the parameters of the electron beam, the dose distributions through the water, the contributions from the electrons and bremsstrahlung photons are scored and compared. It is found that a spatially uniform electron beam results for the case of the most uniform dose distribution and the electrons are the main source for the dose. In addition, the electron differential fluence through the multiple planes of the has been modelled, which provides the base for the further electron beam requirements study.","PeriodicalId":345367,"journal":{"name":"IPAC 21, 24-28 May 2021, Campinas, SP, Brazil","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116456445","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 Upgraded Injector Test Facility (UITF) at Jefferson lab is a CW superconducting linear accelerator capable of providing an electron beam of energy up to 10 MeV. To investigate degradation of the organic compound pollutants, a wastewater treatment beamline at UITF has been designed by using the code GPT (General Particle Tracer). The electron beam is assumed to have 8 MeV electron energy and the transverse radius of sigma around 0.8 to 0.9 cm. It has been found that the rms (by second central moment) energy spread induced by the accelerating cavity is less than 74.5 keV in the simulations. The space charge effect doesn’t affect the beam quality for 100 nA beam current.","PeriodicalId":345367,"journal":{"name":"IPAC 21, 24-28 May 2021, Campinas, SP, Brazil","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121978926","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}
