The main goal of this proposal is the search for a narrow cryptoexotic nucleon resonance by scanning of the p-p system invariant mass in the region (1610-1770) MeV with the detection of p-p and KL decays. The scan is supposed to be done by the variation of the incident p- momentum and its measurement with the accuracy of up to +/-0.1% (better than 1 MeV in terms of the invariant mass in the whole energy range) with a set of proportional chambers located in first focus of the magneto-optical channel. High sensitivity of the method to the resonance under search is shown. The secondary particles scattered from a liquid hydrogen target are detected by sets of the wire drift chambers equipped with modern electronics.Now it is achieved the pion beam momentum resolution better than 0.1% at Pp = 1.5 GeV/c. The wire drift chambers are in preparation. The liquid hydrogen target is tested. The first experimental accelerator run can be at the end of 2008 year.
