	Proposal. An Experiment for Studying Mechanisms of Charmed Paticle Production and Decays in pA-interactions at 70 GeV/c.

In the proposal of an experiment the aimes of a continuation of charm particle production studies started in the framework of experiment E--161 with the SVD set-up are formulated. From an analysis of the existing data on charm hadroproduction obtained in fixed target experiments and of modern theoretical ideas on mechanisms of heavy quark production in hadronic collisions it is shown that conducting an experiment at the energy near the threshold of charm production offers an unique opportunity to verify the intrinsic charm hypothesis and to estimate a possible contribution of such a mechanism to the charm particle yield. A capability of an experiment in this energy range for a study of exclusive nonleptonic decays of $\Lambda_c^+$-baryons is also envisaged. The upgrade for the SVD set-up needed to realize the proposed program of physical investigations, including problems of fabrication of the new precision vertex detector, of the trigger system electronics and of development of the data acquisition system is considered. The results of the detailed Monte Carlo simulation of the charmed events triggering efficiency and of the probability to detect charmed hadron decays with the upgraded SVD set-up are presented. Finally the organization of the data handling system using the interactive program of the graphical analysis of events is discussed and the rate of statistics accumulation is estimated.
