We constructed in 2007 a beam telescope based on CMS Tracker data acquisition prototype cards and APV25 readout chips. The telescope has 8 silicon strip reference detectors and slots for a couple of test modules. The impact point precision of the reference tracks at the location of the test modules is 4 um, the S/N of the telescope is 25 and it has an active area of 4 cm x 4 cm. The telescope...

For testing signal-to-noise, efficiency and resolution of highly irradiated MCz-sensors, a beamtest will take place at CERN this summer, making use of the new beam telescope SiBT. The sensors were produced at the Helsinki Institute of Physics and were irradiated with protons in Karlsruhe and with neutrons in Louvain-la-Neuve. The data of the measured sensor parameters before and after...

Defect Engineering and Pad Detector Characterization
The systematic studies of charge collection were performed on strip and pad detectors of n and p type produced on Fz and MCz silicon. The detectors were irradiated with 24 GeV protons, 200 MeV pions and reactor neutrons up to equivalent fluences of 1.2e15 cm-2. It was shown that the to larger extent the CCE is determined by Vfd for both strips and pads. Although strip detectors perform better...

The charge collection efficiency of µ-strip sensors made with the RD50 mask set with various silicon substrates (n and p FZ and MCz) have been compared to different high doses of neutron and protons, well in the range of the anticipated fluences in SLHC.

Results of charge collection measurements with SCT128 chip will be presented. Measurements were made with miniature p-type microstrip sensors with n-side
readout produced by Micron. Sensors were irradiated with neutrons up to 1 MeV equivalent fluence of 3e15 n/cm2. Collected charge as a function of bias voltage was measured up to 2000 V.
