From the article on the UC Davis Office of Research Website:

Maxwell Chertok and other researchers at UC Davis are testing mechanical structures at the McClellan Nuclear Research Center to find a material that will be able to withstand the radiation environment of the [Large Hadron Collider].

The Compact Muon Solenoid experiment, known as CMS, is a general-purpose detector at the Large Hadron Collider ... The CMS detector acts like a giant digital camera, recording and being exposed to tremendous radiation damage from trillions of proton collisions per year ... Because of this long-term damage, an upgrade for the detector is being developed.

To find a material that would be able to withstand the radiation environment of the collider, Maxwell Chertok, a professor of physics at UC Davis, and other UC Davis researchers, tested mechanical structures made from carbon foam with thermally conductive epoxy at the McClellan Nuclear Research Center. ... The results of the study were published in Journal of Instrumentation.
