摘要：

We tested a new CDC readout scheme utilizing a Charge-to-Time conversion (QTC) technique and multi-hit TDC to record both time and charge information. The new scheme is planned to be used in the BELLE experiment at the KEK B-Factory. We built a prototype Shaper/QTC board and examined the performance with a beam test. This new scheme worked successfully. We obtained the same spatial and dE/dx resolutions as those using an ordinary TDC and ADC readout scheme. (C) 1998 Elsevier Science B.V. All rights reserved.
