The experiments consist of measuring the dose rate due to the 90Sr/90Y source after aluminium shields of various thicknesses (0–15 mm), using TLDs and RADFET. The experiments have been modelled in simple 1D geometries using the MULASSIS tool and in detailed 3D geometries with the GRAS tool. Good agreements have been achieved between the measured and simulated data.","PeriodicalId":392728,"journal":{"name":"2009 European Conference on Radiation and Its Effects on Components and Systems","volume":"59 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114053964","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}

A layer of material such as molybdenum is fabricated integral to a microelectronics scaled CVD diamond cantilever beam such that, as it is irradiated, the layer swells in a predictable manner due to radiation damage, creating a changing state of strain in the bi-layer beam proportional to the fluence. The more the neutron fluence, the larger is the strain and hence the greater the deflection of the beam. This effect is, by the MEMS design and construct, tied to a variable displacement air gap plate capacitor such that the change in capacitance provides a direct measure of fluence.","PeriodicalId":392728,"journal":{"name":"2009 European Conference on Radiation and Its Effects on Components and Systems","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125525349","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}

MATROSHKA is an ESA facility designed to determine the radiation exposure of an astronaut during an extravehicular activity at the ISS. During the project MATSIM a computer tomography scan of the MATROSHKA phantom has been converted into a high resolution 3-dimensional voxel model. The imparted energy and dose inside the model is determined. Part of the project is the phantom validation under reference radiation conditions.
