PERFORMANCE OF THE FRONT-END SIGNAL-PROCESSING ELECTRONICS FOR THE DRIFT CHAMBERS OF THE STANFORD LARGE DETECTOR

This paper reports on the performance of the frontend analog and digital signal processing electronics for the drift chambers of the Stanford Large Detector (SLD) detector at the Stanford Linear Collider. The electronics mounted on printed circuit boards include up to 64 channels of transimpedance amplification, analog sampling, A/D conversion, and associated control circuitry. Measurements of the time resolution, gain, noise, linearity, crosstalk, and stability of the readout electronics are described and presented. The expected contribution of the electronics to the relevant drift chamber measurement resolutions (i.e., timing and charge division) is given.
