摘要：

A drift chamber readout system for about 8000 channels with continuous sensitivity, i.e. concurrent data recording and readout, is described, Drift times are measured in bins of 1.56 ns with respect to a continuously running 40 MHz clock. The clock interval of 25 ns is divided into 16 bins by means of a 16-element delay chain. The length of this chain is linked to the clock interval by a phase-locked loop, An ASIC chip was developed to perform time measurements and data storage for 16 channels. in an asynchronous readout of this chip, data are tranferred to intermediate buffers, for use in a first-level trigger and eventual final readout. The design of the electronics is described and results from data-taking runs are presented. (C) 1998 Elsevier Science B.V. All rights reserved.
