AEON has worked alongside Science and Technology Facilities Council (STFC) and Rutherford Appleton Laboratory in providing design solutions to two aspects of the ATLAS HiLumi Project:

  • Design and manufacture of "Service Modules"
  • Design and vibration analysis of "Detector Support Barrels"

Service Modules are common, modular structures providing power, signal and cooling fluid services to the inner core of the ATLAS Detector, therefore enabling the operation of the silicone detectors mounted on Detector Staves. Most critically the Modules are of a low-active mass, meaning that, the structures and services interfere minimally with the sub-atomic particles produced as a result of a beam collision.


AEON's second area of interest is in the design and analysis of the Detector Support Barrels. In order to build a fully three-dimensional map of a particle's journey (a "trace"), silicone detectors are mounted along the outer cylindrical surface of six concentric cylinders (or Barrels); this allows for the particle to be traced as it speeds away from the epicenter of the collision.

Aeon designed carbon fibre barrels as well as the intermediate adjoining structures required to fully stiffen the assembly, both in term of ground-based AIV, and for in-situ operation when fully loaded with silicone detectors. Of most interest to physicists and engineers alike, is the stability of these structures, as any deformation to the roundness, say, as a result of load bearing or time, will mean the detectors are no longer in the position they once were. In turn, meaning a need to re-calibrate the detector -something which isn't possible once the structure becomes active.
