For the beam intensity and overall stability improvement of INR linac replacement of the first four section cavity of the main part is required. The present cavity is realized as the Disks and Washers (DAW) structure. The new cavity should not lose to the present one in electro dynamical parameters with minimal modifications in the rest linac systems. As the possible structures for the first cavity replacement both proven in exploitation structures and promising developments were considered. The analysis of electro dynamical parameters, coupled RF heating, mechanical processes and manufacturing analysis were performed for the considered structures. For further development the Cut Disk Structure (CDS) option is proposed as the structure with satisfying RF parameters and having the smallest transverse dimensions in comparison with analogues. For the production simplification with minimal losses in electro dynamical parameters an unification of the main geometrical parameters for the four sections cells was performed. The possibility of multipaction in the cavity is considered and an option for its damping is proposed. The manufacturing tolerances for the structure are estimated.
