559 - Two (2) 3He/4He Dilution Cryostat Inserts Pre info notice

new

Preliminary publication of specification is 2025-10-20, Place of execution Skåne län.
Design and manufacture two (2) 3He/4He Dilution Cryostat Inserts (two identical examples). The Dilution Insert will be used for neutron scattering experiments with temperatures below 1 K on a wide range of instruments as part of the sample environment pool equipment. Each dilution insert will operate in conjunction with a top loading "wet" 4He-type cryostat or cryomagnet equipped with a variable temperature insert (VTI). The scope of delivery consists of: • Two systems of the dilution insert in the temperature range down to 50 mK. • Each system contains the dilution cryostat insert and the remotely controllable 3He gas handling system, including 2 LN2 cold traps. • 3He/4He mixture must be provided • All electronic devices for the measurement and control of the dilution stick temperature, 3He/4He gas handling parameters, and the environmental cryostat system shall be capable of remote operation. • Full documentation, drawings and source code. Delivery by 30 November 2026 or earlier.

550 - Filter Tender notice

Deadline for tenders 2025-10-29, the notice is published between 2025-10-08 and 2025-11-05. 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, with a possible option of two additional identical filters. 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.
