550 - Filter Pre info notice

Preliminary publication of specification is 2025-11-17, Place of execution Skåne län.
ESS is looking for a main loop filter in the 1010 helium cooling system for which a tender is needed. Requirement on dimensions, pressure losses, radiation shielding and quality documentation is described in the specification and appendices which will be shared in whole with the full publication of the tender. It is expected that finished filter unit needs to be custom made with the filter elements used being standard elements from a supplier. The filter is to be used to filter helium thats cooling the target wheel. During operation some debris will release from the target wheel and be carried by the helium gas. As the debris can be highly radioactive catching them is important to keep the overall dose-rate down as well gathering the debris in a single place. Once installed the filter unit is only used until it needs to be changed, after that the whole filter unit is handled as waste. When either the radiation level or the pressure loss becomes to high the filter is replaced. The whole filter package, both the pressure vessel and the container is removed and stored. The filter will be stored in a standardized concrete container for radioactive waste which requires that the outer dimensions of the filter don’t exceed the given dimensions.

534 - Cryomagnet for Spectroscopy Tender notice

Deadline for tenders 2025-09-19, the notice is published between 2025-06-17 and 2025-09-19. Place of execution Skåne län.
ESS intends to procure the design and construction of a vertical field split coil superconducting magnet with a minimum central magnetic field of 10.5-14 Tesla and a variable temperature insert (VTI). The latter shall allow normal operation down to 1.5 K or the insertion and cooling of a dilution and/or He3 ultralow temperature (ULT) insert (ULT inserts not part of this tender). The magnet will be used to perform scientific experiments with high magnetic fields and (very) low temperatures on neutron-scattering instruments. The magnet will be principally used on the neutron spectroscopy instruments CSPEC and TREX, so very low background scattering is extremely important. For this reason, the magnet will sit inside a vacuum tank containing the neutron detector assemblies. In addition, material in the main and scattered neutron beam paths must be minimised and detector coverage maximised. A small amount of blocked scattering within the detector range is permitted, to provide additional coil support. This must however be kept to a minimum, and the full horizontal range available with two possible magnet orientations. These instruments are designed to have highly non-magnetic environments, but the supplier will perform simulations to verify both static and dynamic magnetic forces where appropriate and design the magnet to work in the instrument environment. Dynamic forces may occur in the event of an accidental quench. Key specifications: • Alternative offers for 3 fields: 10.5T, 12T, 14T • Symmetrical field • Vertical opening: +/- 7° • Horizontal detector coverage: -36° to +144°, with maximum 2 obstructions in that range, of minimum possible angular range. No more than one obstruction in the 0°-90° range. • Two alternative beam paths to provide full horizontal detector coverage. • 50 mm diameter accessible sample space, within VTI • Sample size 1cm x 2 cm (h x v) • Temperature range 1.5 K – 300 K • Recondensing helium bath, zero boiloff in standby mode. Delivery by mid 2027 or earlier
