In order to provide acceptable tracking performance at the increased luminosity present at an upgraded LHC it will be necessary to upgrade the CMS strip-tracker.
This will require an increase in the number of readout channels with respect to the current tracker whilst maintaining or even reducing the power consumption of the device.
The CMS Binary Chip (CBC) has been designed to provide readout of silicon strip trackers ( both N-in-P and P-in-N ) whilst having very much reduced power consumption compared to the current analogue readout chip the APV.
Results on CBC performance at room temperature, connected to test pulses at the input, are presented elsewhere.
Initial results from the CBC bonded to a silicon sensor are presented. The room temperature tests were repeated at a range of temperatures between -40degC and +40degC. A pulsed LED, pulsed focussed laser and radioactive sources were used to deposit charge into the sensor.
