✦ Synopsis

A high resolution vertex detector has been realized to operate in the photoproduction experiment F.687 scheduled to run at Fermilab Tevatron for heavy flavor searching [S. Sala, Proc. of Physics in Collision 3 (1983) 459]. The vertex has 12 planes of silicon microstrip chambers with more than 8000 channels, all equipped with a low noise front-end electronics and ADC read-out. The ADC module developed on purpose, has histogramming facility for each channel and makes use of look up tables for pedestal correction and gain equaJization.

A sophisticated database system has been developed, based on DEC DATATRJEVE. It contains general and detailed informations on all the items of the vertex, such as detectors position and geometry, electronic connections, look up tables generating function, selected histograms and any useful parameter of the system. Once initialized for a given configuration, it can be manually or automatically conditions as detected by the monitor and calibration procedures.

After a brief description of the detector, the general architecture and the underlying philosophy of the Database system will be discussed together with the main procedures operating on it.
