In designing the radiation-tolerant silicon microstrip sensors, the onset of microdischarge must e expelled above the maximum operation voltage. The difficulty is enhanced in the n-in-p sensors, with the existence of p-n junction in the n-strips and

A serial powering scheme is a promising solution to reduce the total power, number of cables, passive detector material and overall the cost for large-scale silicon tracking detectors. We present a control and monitor system for a serial powering sch

In accordance with the super LHC program, which plans to increase a collision rate of LHC by tenfold, the ATLAS silicon strip trackers need to be upgraded to overcome proportionally higher data rate and harsher radiation environment. Immediate concer
