Abstract
GaAs strip detectors are of interest because of their radiation hardness at room temperature and the high absorption coefficient of GaAs for x-rays. T he detectors currently under development will be used in the VLQ-experiment at the H1 experiment at the HERA collider. This will be the first high ene rgy physics experiment where GaAs detectors will be used. The detectors hav e a sensitive area of 5 x 4 cm with a pitch of 62 mu m. Due to the high den sity of channels the biasing resistors and coupling capacitors are integrat ed. For the resistors a resistive layer made of Cermet is used. The propert ies of the first fully integrated strip detector are presented.
