A double-sided silicon strip detector with capacitive read out and a new method of integrated bias coupling
Abstract
By introducing a new biasing concept it was possible to implement capacitive coupling with a relatively simple production process. Capacitive coupling eliminates the problem of electronic readout saturation caused by leaky strips. This advantage is of particular value for the n-side where a current caused by differences in the input voltage levels of the readout electronics could make any measurement impossible. Double-sided readout increases the position information and is advantageous for use in detector systems where aspects like compactness and minimization of scattering material are important. Furthermore, by using the pulse height correlation, multihit ambiguities may be decreased. Static measurements confirmed all principal performance properties of the device. Further tests were performed in the readout electronics environment of the ALEPH minivertex detector under laboratory as well as under operating conditions in a test beam at the CERN SP synchrotron and have shown the detectors functionability.
