Test results of the reconstruction technique in track chamber with the internal target on the simulated events

The testing of the geometrical reconstruction technique of events for the SQN-200 streamer chamber with the target in the fiducial volume is presented. Effect of measuring errors on the reconstruction accuracy of the invisible vertex spatial coordinates is investigated. Modified version of the WORM2 program is used for generation of artificial events in the chamber and for projection of these events onto various film views. Consequent data processing using the corresponding program for the geometrical reconstruction allowed to evaluate the accuracy in investigated parameters and their dependence on measurement errors
