The LHC upgrade will extensively increase the area of silicon detectors used in the ATLAS experiment and require substantial changes to the readout system of both the ATLAS and CMS experiments. The two experiments are expected to use optical systems for part of the data and control paths which must withstand levels of radiation equivalent to a dose of(More)

Optical fibers in the readout system for the LHC upgrades will operate in a harsh radiation environment. The fibers within 12 meters from the front-end detectors are exposed up to 250 kGy(Si) total ionizing dose in their 10 year operational life time. In some applications, the fibers within the tracking volume are kept in a cold environment near -25 °C. The(More)
Silicon nanoclusters (Si-ncs) embedded in silicon nitride films have been studied to determine the effects that deposition and processing parameters have on their growth, luminescent properties, and electronic structure. Luminescence was observed from Si-ncs formed in silicon-rich silicon nitride films with a broad range of compositions and grown using(More)
