	Funding: Fermilab is operated by Fermi Research Alliance, LLC, under Contract DE-AC02-07CH11359 with the US Department of Energy. The Integrable Optics Test Accelerator (IOTA) is a research machine currently being designed and built at Fermilab. The research program includes the study of nonlinear integrable lattices, beam dynamics with self fields, and optical stochastic cooling. One section of the ring will contain an electron lens, a low-energy magnetized electron beam overlapping with the circulating beam. The electron lens can work as a nonlinear element, as an electron cooler, or as a space-charge compensator. We describe the physical principles, experiment design, and hardware implementation plans for the IOTA electron lens.

	We present the last advances in the operation and construction of the ESS-Bilbao 3 MeV proton beam injector. The proton ECR source allows to change the distance between the plasma chamber and the first extraction electrode, acceleration gap. The beam has been characterised at different acceleration gaps by current transformers, wire scanners and photographs of 2d profiles. In addition, we present the status of the construction of the RFQ; which is at its beginning.

	J.S. Cao, H. Geng, R.L. Liu, C. Meng, Y.F. Sui, F. Yan, Q. Ye IHEP, Beijing, People's Republic of China
	As a test facility, the design goal of C-ADS Injector I is a 10mA, 10MeV CW proton linac, which uses a 3.2MeV normal conducting RFQ and superconducting single-spoke cavities for accelerating. The RF frequency of C-ADS Injector I accelerator is 325 MHz. In accordance to the progress of construction and considering the technical difficulties, the beam commissioning of C-ADS Injector I is carried out in 3 phases: Phase 1, with ECRIS + LEBT + RFQ + MEBT + TCM (two superconducting cavities), to reach 3.6 MeV; Phase 2, with ECRIS + LEBT + RFQ + MEBT + CM1 (seven superconducting cavities), to reach 5 MeV; Phase 3, with ECRIS + LEBT + RFQ + MEBT + CM¹⁺ CM2 (same as CM1), to finally achieve the design goal of C-ADS Injector I. This paper summarizes the beam commissioning in 3 phases and focusing on the third phase.

	Funding: Work supported by the National Natural Science Foundation of China (No. 11575265, 11427904) and the “973” Program of China (No. 2014CB845501). Electron cyclotron resonance (ECR) ion sources are widely used in heavy ion accelerators for their advantages in producing high quality intense beams of highly charged ions. However, it exists challenges in the design of the Q/A selection systems for mixed high intensity ion beams to reach sufficient Q/A resolution while controlling the beam emittance growth. Moreover, as the emittance of beam from ECR ion sources is coupled, the matching of phase space to post accelerator, for a wide range of ion beam species with different intensities, should be carefully studied. In this paper, the simulation and experimental results of the Q/A selection system at the LECR4 platform are shown. The formation of hollow cross section heavy ion beam at the end of the Q/A selector is revealed. A reasonable interpretation has been proposed, a modified design of the Q/A selection system has been committed for HIRFL-SSC linac injector. The features of the new design including beam simulations and experiment results are also presented.
