- Abstract
- X-rays have been used for imaging for over 100 years due to their unique interaction properties with matter that allow them to penetrate samples and reveal detailed structural information on the atomic scale. NanoMAX is one of the first beamlines to be developed at the new Swedish synchrotron radiation source MAX IV. It will use high brilliance, coherent X-radiation to utilize these properties fully and aim for imaging with nanometer resolution. The beamline is planned to open for users 2016 and will then offer two experimental stations. One of the stations will be coarser and flexible in regard to the sample requirements and one will have a planned beam size around 10 nm for nanoscale objects. To test the beamline and make use of it... (More)

One of the stations will be coarser and flexible in regard to the sample requirements and one will have a planned beam size around 10 nm for nanoscale objects. To test the beamline and make use of it before the installment of the permanent experimental station, a test setup – or prototype – of the higher resolution experimental station, will be built, tested and operated at the inauguration of MAX IV June 21st 2016. The aim of this project has been to design, assemble and evaluate this test setup with respect to stability. The setup consists of the final focusing step of the beamline which is a Fresnel zone plate, an aperture to exclude X-rays of higher orders, and a placeholder for a future sample. All components are held by holders, designed as part of this master’s project, and placed on piezo stages that are controlled by software, also developed within the frame of this project. This thesis describes the four steps of the process: Collecting theoretical and practical knowledge, designing components and building the setup, developing controlling software and testing the stability of the setup. It also presents the final setup and results from successful stability tests, showing that the eigenfrequency of the system is within the required limits. (Less)

- MAX IV kommer bli världens första ultrabriljanta synkrotronljusring. Ringen använder magneter för att böja elektroners bana på ett helt nytt sätt och kommer därför producera röntgenljus i strålar som blir finare och mer fokuserade än vad någon annan anläggning i världen kan göra. Röntgenstrålarna leds ut i långa rör för att kunna användas till experiment. Ett av strålrören heter NanoMAX och det kommer att användas för att kunna ta bilder med upplösning i världsklass. Eftersom röntgenljus kan gå igenom material bättre än annat ljus kan man använda strålröret för att ta bilder, inte bara på ytan av ett prov, utan även på insidan. Man kan till exempel upptäcka om det finns spänningar i strukturen på atomnivå hos nanomaterial, använda... (More)
- MAX IV kommer bli världens första ultrabriljanta synkrotronljusring. Ringen använder magneter för att böja elektroners bana på ett helt nytt sätt och kommer därför producera röntgenljus i strålar som blir finare och mer fokuserade än vad någon annan anläggning i världen kan göra. Röntgenstrålarna leds ut i långa rör för att kunna användas till experiment. Ett av strålrören heter NanoMAX och det kommer att användas för att kunna ta bilder med upplösning i världsklass. Eftersom röntgenljus kan gå igenom material bättre än annat ljus kan man använda strålröret för att ta bilder, inte bara på ytan av ett prov, utan även på insidan. Man kan till exempel upptäcka om det finns spänningar i strukturen på atomnivå hos nanomaterial, använda informationen för att utveckla bättre tillverkningsprocesser, och i slutändan lära sig att göra bättre batterier, solceller, lysdioder, bildskärmar, datorer eller mobiltelefoner. Som en del i byggandet av NanoMAX har en prototyp av experimentstationen tagits fram. Det är den del där ljuset fokuseras och skannar provet innan det fångas upp av en detektor och skapar en bild. För att kunna styra prototypen har flera datorprogram skrivits, och därefter har prototypens stabilitet undersökts med bra resultat. (Less)
