A VME-Macintosh data acquisition system with ECL readout

A new Data Acquisition System has been developed at LNS to match the experimental request of handling hundreds of parameters and spectra with an input event frequency of a few kHz. Both the traditional CAMAC and a new faster ECL readout dataways are supported. To enhance the system flexibility three different kinds of CAMAC ADCs can be used (GAN'ELEC QDC1612F, FERA 4300B, SILENA ADC4418/V). Two HSM8170 interfaces are adopted between the ECLbus and the VMEbus as ECL-VME buffers. An EXB-8200 tape unit is connected to the system for off-line processing data storage.
