A three-megavolt tandem accelerator for material, nuclear and life science research

The University of Jyväskylä is acquiring a 3 MV electrostatic tandem accelerator and related ion-optical components. The accelerator will be installed in the existing Accelerator Laboratory main target hall of the K130 cyclotron. The procurement includes 3 MV tandem accelerator, high-energy focusing optics and high-energy switching magnet. The existing H-, He- and cesium sputtering ion sources from the 1.7 MV Pelletron accelerator will be fitted to the new system. The low energy vacuum system and injector will be designed and built separately from this procurement. The beam lines after the switching magnet will also be moved from the 1.7 MV Pelletron accelerator. The area reserved for the new accelerator platform is 10x20 m, and the walls and ceiling used for radiation protection will be constructed from concrete blocks. The concrete floor can easily carry the weight of the system, but no cable channels can be chased to it. Approximate layouts for two example solutions will be provided with the tender documents. The procurement is mainly funded by means of FIRI funding from the Research Council of Finland. Contracting authority (JYU) may suspend the procurement procedure if the tenders exceed the budget available for the procurement. Prior references of comparable systems are required.
