Microstrip silicon detectors with orthogonal readout on opposite sides have been designed and fabricated. The active area of each device is 25 cm2 and the strip pitch is 25-mu-m on the junction side and 50-mu-m on the opposite ohmic side. A space resolution of 15-mu-m on the junction side (100-mu-m readout pitch) and 24-mu-m on the ohmic side (200-mu-m readout pitch) has been measured. We also report on AC-coupling chips, designed and fabricated in order to allow AC connection of the strips to the amplifiers. These chips are 6.4 x 5.0 mm2 and have 100-mu-m pitch. Both AC-couplers and detectors have been installed as part of the ALEPH minivertex.

Abstract
Microstrip silicon detectors with orthogonal readout on opposite sides have been designed and fabricated. The active area of each device is 25 cm2 and the strip pitch is 25-mu-m on the junction side and 50-mu-m on the opposite ohmic side. A space resolution of 15-mu-m on the junction side (100-mu-m readout pitch) and 24-mu-m on the ohmic side (200-mu-m readout pitch) has been measured. We also report on AC-coupling chips, designed and fabricated in order to allow AC connection of the strips to the amplifiers. These chips are 6.4 x 5.0 mm2 and have 100-mu-m pitch. Both AC-couplers and detectors have been installed as part of the ALEPH minivertex.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
