	The Krion-6T ion source is an electron string ion source (ESIS) of multicharged ions. It will be used as an ion source for the heavy ion linac at the NICA project, but has been tested on an existing injection facility - Alvarez-type linac LU-20 with new RFQ type fore-injector. The transverse emittance measurements were carried out on the initial part of channel (IPC) of the low energy beam transport (LEBT) channel, between the ion source and RFQ fore-injector by pepper-pot method. Beams of multicharged Argon and Xenon ions are observed. Measurements of the profile and emittance were performed over several energies for each type of ions. The results of the measurement are presented, and some points of emittance calculations are considered.

	Light ion injector for future NICA project contain several resonator: buncher, RFQ, Alvarez-type linac LU-20, and possibly debuncher, that all work on same resonant frequency 145.2 MHz. Base frequency for all resonators in injector produced by LU-20 linac, worked in self-excited loop mode. Low-level RF control system of injector should capture RF signal from LU-20 linac within front of signal and generate output RF signals with same frequency on others resonators, with regulated phase difference between channels. Additionally, low-level RF control system should tune resonant frequencies of RFQ, buncher and debancher. Presented LLRF system was successively work within several years. LLRF controllers design, possibilities, and key stabilization techniques are presented.

	An Source of Polarized Ions (SPI), developed at JINR, produces pulsed beams of polarized protons and deuterons for NUCLOTRON accelerator. The accelerated polarized ion beams will be injected into future NICA collider. In order to reconcile requirements of a RFQ fore-injector of the Alvarez type linear accelerator LU-20, it is necessary to measure a transverse emittance of the ion beams produced by the SPI. The emittance of beams of polarized deuterons and polarized protons was measured by the pepper-pot method. The results of measurements of the emittance and profile of the polarized ion beams are presented.
