At the European Laboratory for Particle Physics (CERN), commercial greases and oils are extensively used to lubricate moving devices operating in high-radiation areas, absorbing doses up MGy range. Due their sensitivity radiation, lubricants can become fluid or solid operation, potentially causing component failures compromising operation of accelerator complex. CERN is therefore developing methodologies select radiation tolerant critical Beam Intercepting Devices (BIDs) such as high-power...
