Description
CMS plans to increase both its luminosity and center of mass energy in future upgrades. As such, more radiation hard silicon must be used for the inner tracker. The HPK campaign aims to determine which sensor material, polarity and geometries will work best under these high radiation conditions. One of Brown Universities' contributions to this project includes charge collection efficiency (CCE) measurements using a Sr-90 beta source and the ARC read out system in both non-irradiated and irradiated Float Zone (FZ) and Magnetic Czochralski (MCZ) multi-geometry sensors.
An overview of our setup, data analysis, and results from Long-Term (1 week) CCE and Voltage ramp measurements on non-irradiated sensors (n- and p-type with 200um thickness) will be presented.
