                    Abstract
    The MQT300 tri-range Charge-to-Time Monolithic IC is under development at LeCroy Corporation. Designed to be detector mounted, the MQT will convert charge to time with a least count of 10 fC or better, with a dynamic range of at least 18 bits. Time differences are output to crate based TDCs such as the LeCroy 1877 FASTBUS TDC.

    The VISyN High Voltage System provides, in a standard, networked architecture, high voltage generation for both chamber and phototube detector systems. ARCNET and Ethernet interfaces allow networking of multiple high voltage mainframes.
