Detector Characterization
This contribution gives an overview on the campaign to evaluate the planar silicon sensor options for the CMS Tracker Upgrade. This evaluation is done with one industrial supplier, which is capable to provide the large quantity of sensors needed for the Tracker volume at very high quality. Wafers are processed on various materials (FZ, MCz, Epi), with several dopings (n-type, p-type with...

Detector Characterization
The aim of the CMS-HPK-Campaign is to find a new Material for the HL-LHC Upgrade of the CMS-Tracker. Therefor a lot of different structures and materials is produced by HPK. A first sample of FZ Diodes of n- and p-type has been neutron and proton irradiated with 10^14 neq. Their IV/CV-characteristics will be presented.

In a large campaign started by the CMS collaboration to identify the future silicon sensor technology baseline for a new tracker for the high-luminosity phase of LHC, a first set of floatzone diodes was irradiated to a fluence of 10^14neq/cm2 with protons, neutrons and mixed exposure. Measurements of leakage current, depletion voltage and charge collection efficiency with an infrared Laser on...

Current amplifiers with and without integrated Bias-T and laser drivers (with heads) were developed for the dedicated use in TCT. The results from the first tests will be shown.

Silicon n-on-p strip detectors produced by CIS, have been irradiated with pions in a fluence range 2e14pi/cm^2-1e15pi/cm^2. The irradiated detectors have been measured by means of the Edge-TCT and Alibava CCE setup, as well as standard CV/IV characterization. The detectors have shown a fairly low gc value. Investigation went in the direction of looking for correlation between the different...

Charge collection measurements with both Edge-TCT and Alibava on neutron i pion irradiated micro-strip detectors will be presented. Edge-TCT measurements were made in reverse and forward bias and include several annealing steps at 60C (according to the standard CERN scenario), as well as different temperature and laser frequency steps.

For the development of radiation hard Si detectors for the SiD BeamCal program for International Linear Collider (ILC), n-type MCZ Si detectors were irradiated first by fast neutrons to fluences of 1.5x10^14 and 3x10^14 neq/cm2, and then by gamma. It is found that gamma radiation has suppressed reverse annealing in neutron irradiated detectors which were subject to gamma radiation during the...

Temperature dependence of the generation current is analysed using the experimental and theoretical data for intrinsic carrier concentration. It is recommended that the current is scaled with temperature by the following formula: T^2 exp(-1.21 eV/2kT) both for non-irradiated and irradiated Si detectors.
