Description
In order to cope with very high radiation dose and hadron fluences at the High Luminosity Large Hadron Collider (HL-LHC), a new silicon Inner Tracker will be built for the Phase-2 Upgrade of the CMS experiment. The new Inner Tracker will contain 2 billion silicon pixels. These pixel modules will be composed of pixel sensors with pixel size of 100x25 um2 or 50x50 um2 and a new ASIC, designed in 65 nm CMOS technology, developed by the RD53 collaboration.
CMS is currently testing multiple silicon-based particle detector technologies, including thin planar sensors and 3D sensors, at Fermilab. In order to test the performance, efficiency, and resolution of these devices, a pixel telescope, pointing resolution of ~5 um, consisting of 10 layers of silicon particle detector devices is placed in the 120 GeV proton beam at the Fermilab Test Beam Facility. By comparing reference tracks from the pixel telescope, one can evaluate different detector technologies. Fermilab Irradiation Test Area (ITA), uses a 400 MeV Linac protons to irradiate the sensors.
The resolution, efficiency, and charge collection of planar and 3d pixel sensors before and after irradiation will be shown. These test results inform the choice of sensor technology for the innermost layers of the upgraded pixel detector.
