A Swiss intergovernmental organization / research centre is looking for supplier of around 3000 shielding elements made from Tungsten Heavy Alloy (WHA) with low magnetic permeability. The partner sought for a manufacturing agreement will be able to manufacture and deliver the shielding elements according to the tolerances listed.
The accelerator currently used by the Swiss NGO is installed in a 27 km circumference tunnel, about 100 m underground. Its design is based on superconducting twin-aperture cryo-magnets which operate in a superfluid helium bath at 1.9 K.
A project is running with the aim to upgrade the collider after 2020-2025 in order to maintain scientific progress and exploit its full capacity. By increasing its peak luminosity by a factor five over nominal value it will be able to reach a higher level of integrated luminosity, nearly ten times the initial design target. To this aim, the research centre is exploring new beam configurations and new advanced technologies in the domain of superconductivity, cryogenics, rad-hard materials, electronics and remote handling.
New beam screens are being designed for the beam apertures of the new cryo-magnets to ensure the required beam aperture while maintaining the ultra-high beam vacuum.
The beam screens will be equipped with tungsten heavy alloy shielding elements to intercept collision debris from the experiments, in order to minimise the heat load to the 1.9 K cryogenic system.
The Swiss NGO is looking for partners able to fulfil a manufacturing agreement for these types of tungsten shielding elements, according to the specifications detailed in the following and to drawings that will be provided separately.
The chemical composition shall be in accordance with the following parameters:
The partner sought is qualified in the manufacturing and testing of tungsten heavy alloy (WHA) parts.
The tasks to be performed by the partner sought:
