About This Opportunity

Translated

This tender concerns the supply and commissioning of a Neutron Velocity Selector (NVS) system. The scope of work includes the delivery and parameterization of a new velocity selector (Selector 2), which will replace the existing NVS20 from Airbus Defence and Space GmbH. Additionally, the tender requires the delivery and parameterization of a new converter with an integrated monitoring and control system for Selector 2. Furthermore, a new converter with a new monitoring and control system must be supplied and parameterized for Selector 1 (currently the NVS40, also from Airbus Defence and Space GmbH). The installation of the converters and associated monitoring and control electronics for both selectors into a new, shared 19" rack, followed by acceptance testing, is also part of the contract. The project includes on-site commissioning of the complete system, performance verification, and user training. Specific on-site activities must be carried out by personnel meeting the requirements for "occupationally radiation-exposed persons," with proof of availability to be submitted with the bid. Performance tests will include demonstrating vibration stability in the primary and secondary wavelength bands of the new selector, as well as for Selector 1 with its new converter. A 72-hour long-term test at various speeds (3,000-26,000 rpm) on-site is required. Comprehensive documentation, primarily in English and supplemented in German, is also a deliverable. The primary utilized wavelength band for the new selector is specified as 2.89 Å to 6.9 Å, with no forbidden wavelengths due to mechanical resonances. A further usable wavelength band is from 10.1 Å to 13 Å. The Heinz Maier-Leibnitz Zentrum (MLZ) at the Technical University of Munich in Garching is the project location.

This is a supplies contract in the Research, information and communication technology and architecture and engineering sectors, with a focus on R&D equipment, Hardware, Electrical Engineering and Project Management. Located in Germany, Europe, this opportunity is open to firms and consortiums.
