	INR Linac has been operating with 50 Hz beam repetition rate so far. Increasing the repetition rate up to 100 Hz is of importance as it results in doubling of the beam intensity. To solve the task several accelerator systems must be modernized but the most critical one is the DTL rf system (up to 100 MeV). The problems related to the DTL rf system repetition rate increasing are described. One of them is a 50 Hz modulation of a 100 Hz rf pulse sequence. Though the instabilities of accelerating field due to the modulation are reduced by the feedback systems, nevertheless exploration of the effect and its minimizing is of importance. The analysis of the effect is given and the results of experimental studies are presented.

	Emittance measurements at the exit of INR linac are of importance for proper beam matching with the beam line of the downstream experimental facility. Emittance ellipses are reconstructed from beam profile data obtained with three wire scanners and one ionization beam cross section monitor (BCSM). A possibility of quadrupole gradients adjustment not only increases the reconstruction accuracy but also enables to find emittances with BCSM data only. The latter provides completely transparent measurements and due to large BCSM range can be done within a wide range of beam currents.
