[en] The BCD Silicon strip Vertex Detector is constructed of 10 identical central region modules and 18 similar forward region modules. This memo describes a method of assembling these modules from individual silicon wafers. Each wafer is fitted with associated front end electronics and cables and has been tested to insure that only good wafers reach the final assembly stage. 5 figs

[en] This paper is based, in part, on an internal review conducted by the Silicon Tracker Group in the ATLAS experiment at CERN. Its purpose is to examine the current status of on-detector read-out electronics appropriate to the LHC environment, and in particular to expose any new development that might be required for use with the high level one trigger rate requirements in the LHC-B beauty experiment planned for the LHC.

[en] While silicon detectors have come into general use in measuring alpha and beta radition, the measurement of gamma radiation is still done mainly by GM tubes especially in portable devices. This is due to the relatively small sensitivity of the silicon detectors and their high dependence on the gamma energy as well. VIDEOTON Development Institute has been enganged in manufacturing silicon detectors for radiation protection purposes for more than 10 years. The sensitivity of 5 - 50 mm³ detectors is equivalent to that of small size GM tubes. Moreover, silicon detectors have a lot of advantageous properties in comparison with GM tubes, namely, higher stability, endless operating life time, ability to operate reliably in extremely high dose rate /above 100Gy/h/, and they don't need high operating voltage. It is possible to make the application of silicon detectors easier by using hybrid integrated circuits which have been developed for their electronics. This paper gives information on the characteristics of silicon detectors, their advantageous and disadvantageous features as well. It also demonstrates methods applied in order to reduce the temperature dependence of the noise level and energy dependence of sensitivity. Finally, the measuring results of radiation protection probes built of hybrid circuits will be given. (Author)

[en] The ATLAS pixel detector consists of three barrel layers and three disk-layers in the endcaps, comprising a total of 80 million pixel cells. Commissioning for the pixel detector has started in spring 2008. A representative selection of commissioning results is given.

[en] A radiation detector is described which comprises a wafer of semiconductor material (silicon) having a high-low junction formed on one planar surface, the high-low junction also continuing around the edge and an annular region at the periphery of the reverse planar surface. An electrically isolating region is formed around the inner edge of the annular region of the reverse planar surface of the water and a rectifying junction formed over the remainder of the reverse surface of the wafer. Means are provided for making electrical contact to the high-low and rectifying junctions. (author)
