Description
The CMS collaboration will upgrade the CMS pixel detector in 2016/2017. For this upgrade the readout chip (ROC) had to be modified. An improved readout logic, larger data buffers and the digital readout scheme promise a significant increase in hit detection efficiency at the high particle flux expected in the LHC environment of a luminosity of $2\times 10^{34}$ cm$^{-2}$s$^{-1}$. To test the chip’s high rate capabilities a test beam was performed at the Fermilab Test Beam Facility (FTBF). The chip was tested in a telescope with rates of up to 500 MHz/cm$^2$. This talk will describe the new ROC, the telescope electronics and show results from the test beam.
