AB - The Cut Disk Structure (CDS) is recommended for replacement of the first cavity of the main part of INR linac. For the cavity work stability there should be no multipactor at operating regime. CDS structure was first set on exploitation at DESY PITZ electron linac. For this cavity according to the analytical estimation multipaction should appear at the operating power level in coupling cells, but it was not approved by the numerical simulation with both accelerating and coupling modes excitation for RF energy transfer along the cavity. The multipactor appears only with the secondaty emission yield (SEY) growth which could happen if the inner surface of the cavity is polluted. The results of multipactor investigation in CDS PITZ were used as reference for the CDS structure for the first cavity of the main part of INR linac. The analytical estimation and numerical simulation of multipactor in CDS INR structure shows the appearance of the discharge in coupling cells with the OFC copper SEY for the operating regime of the cavity. An option for the multipactor damping with the forced excitation of oscillations in coupling cell with voltage higher than upper multipactor limit was considered.
