Description
We have executed a beam test of n-in-p silicon strip sensors aimed for the High Luminosity LHC(HL-LHC) upgrade of the ATLAS SCT(Semi-Conductor Tracker), in Dec. 2011 at Reseach Center for Nuclear Physics (RCNP). The data acquistion system was made of (1) the ABCN chip with a new readout system using an universal read-out board called “SEABAS" and (2) a beam defining telescope with VME readout modules. The telescope defined the beam position of 392 MeV protons with a spacial resolution of approximately 10 µm. The new sensors were irradiated using 70 MeV protons at Cyclotron and Radioisotope Center (CYRIC) to 1x10^12 to 1x10^15 n_eq/cm^2. The muti-hit ratio, the charge collection capability, the sensitive region on the strip end around the PTP structure, of the non-irradiated and irradiated new sensors were compared. In the non-irradiated sensor, the sensitive region on the strip end reached to the bias rail, while in the irradiated to the 10^15 n_eq/cm^2 sensor reached only to strip end.
