UKRI-3102 Precision Tools for the Assembly of ATLAS Inner Tracker Modules

ATLAS is a particle physics experiment at the Large Hadron Collider (LHC) at CERN (www.atlas.ch). The ATLAS detector is due to be upgraded and the ATLAS group at the UKRI is part of the construction of a new silicon strip tracker at the heart of the upgraded detector. This project is part of a worldwide collaboration involving more than 3000 scientists from 174 institutions. The tracker is made up of silicon strip sensor modules which are arranged in a precise series of expanding shells around a central beamline. Each module is assembled in a series of manual assembly steps, which are homogenised throughout several production sites across the UK. A high level of precision is required to provide the alignment required for the intended precision tracking within the detector. UKRI provides the tools for module building to the collaboration partners. The scope of this tender includes: • precision manufacturing of tools from aluminium, • hard anodised (Type III sulphuric anodising) to 50µm thickness, • text on required pieces must be engraved or laser etched, and • dimensions of all tools need to be correct after hard anodisation.
