Abstract [en]

GEMS PET Systems AB manufactures a type of particle accelerator called cyclotron. A cyclotron accelerates charged particles in order to hit so-called targets. The acceleration takes place inside a vacuum chamber and currently BEVs or beam exit valves are used to maintain this vacuum during target maintenance. The problem with the BEVs are that they can become overheated during cyclotron use. The commissioner requested a detail made in one and the same part that houses all BEVs currently used. Additionally, suggestions for how the new part could be connected to a cooling device was requested. The commissioner wanted to use parts of a valve provided by a supplier. A prototype for the valve-housing was designed and ordered to test the compatibility between this new valve-housing and the parts from the supplier. The idea was to use some of the prototype’s features in the new detail. A concept generation was made for the new detail with tools like Brainstorming and SCAMPER. CAD proposals were created for the new detail according to the chosen concept, which was then shown to employees at GEMS PET Systems AB and they deemed that the concept was possible to realize. The prototype was not delivered before the project’s conclusion and could not be tested. Consequently, it is not possible to determine if the suggested concept is compatible with the parts from the supplier nor if it is able to maintain vacuum, but the proposed concept meet the other requirements set out in the specification.
