The conception of Multi-purpose Hadrons Facility (MHF) began to be discussed at ITEP in the late ~2010s when ITEP-TWAC facility was intensively exploited for physical and applied research with the use of accelerated proton and ion beams varied in a wide range of operating parameters. Technological developments have continued to expand the scope of beams utilizing in diverse fields of science, medicine, industry and education. The ITEP-TWAC facility was decommissioned in 2012 and continues to remain in a state of waiting for reasonable decision on its recovery and upgrade, but conception of MHF is alive and aims at creating a technological base of particle accelerator technique intended for generation of proton and ion beams, covering the needs of many areas of fundamental, applied and technological research and industrial applications, represents a significant scientific and practical interest for modern and future engineering community. Created MHF environment should obviously be friendly and flexible for collaboration with industry, universities, and other national and foreign labs to provide continuous intelligent and technological progress. The key components of the MHF mission and vision are presented.

Design of the high-current ion injector for ions with z/A<=0.5 is described. The system consists of the laser-plasma generator based on a repetition rate laser with peak power 100MW/1Hz, a vacuum target chamber with optical focusing system with variable relative apertutre, a beam extraction system and the I-4 ion RFQ accelerator of ITEP. Characteristics of ion component of plasma produced by pulses of the CO2 laser were studied, when irradiating a solid carbon target using long-focus objective at power density of 1.5·10¹¹ W/cm². This work is of considerable interest in a wide area of applications of accelerated particle beams, including fundamental studies of state of matter in particle colliders (NICA project at JINR), radiation damage simulation and hadron therapy for cancer treatment. The goal of this work is to investigate characteristics of ions in expanding laser plasma. Their energy distribution is important for extracting an ion beam and its further acceleration. Time-of-flight technique using a high resolution energy analyzer allowed to explore dynamics of the plasma expansion by determining the time when ions with specified charge and energy leave plasma plume relative to the incident laser pulse. This research is valuable for adapting an intensive beam from laser ion source to the accelerator, improving acceleration efficency and rising the amount of accelerated particles.
