【 摘 要 】

The hadron endcap (HE) calorimeter is one of the major sections of CMS detector, used for measurement of the hadrons energy. Phase1 upgrade of the front-end electronics components in the HE calorimeter is being prepared, in particular to improve ability to handle increased pile-up and mitigate radiation damage of optical system in the high eta region. Tests of Phase1 HE Front-end system including new photo-sensors, silicon photomultipliers (SiPM), as well as new charge integrator encoder (QIE11) were performed in the Burn-in station in b904 at CERN. In this note, analysis and measurement results for the new generation front-end electronics components are presented.
