The Electron-Ion Collider (EIC), presently under construction at Brookhaven National Laboratory, will collide polarized high-energy electron beams with hadron beams, achieving luminosities up to 1 × 10³⁴ cm^¿2 s^¿1 in the center-of-mass energy range of 20-140 GeV. To achieve such high luminosity, we adopt high bunch intensities for both beams, small and flat transverse beam sizes at the interaction point (IP), a large crossing angle of 25 mrad, and a novel strong hadron cooling in the Hadron Storage Ring (HSR) to counteract intra-beam scattering (IBS) at the collision energy. In this talk, we will review the beam dynamics challenges in the design of the EIC, particularly the single-particle dynamic aperture, polarization maintenance, beam-beam interaction, impedance budget and instabilities. We will also briefly mention some technical challenges associated with beam dynamics, such as strong hadron cooling, multipoles and noises of crab cavities, power supply current ripples, and the vacuum upgrade to existing beam pipes of the Hadron Storage Ring of the EIC.

MOA3I2	Accelerator Challenges in the Fermilab Neutrino Program
	J.S. Eldred Fermilab, Batavia, Illinois, USA
	In Fermilab’s 2022-2023 proton complex run, Fermilab recovered from an unexpected failure in the neutrino focusing horn to achieve a record beam power of 960 kW. For Snowmass and P5, Fermilab recently proposed a new upgrade plan known as Accelerator Complex Evolution (ACE) to occur after PIP-II upgrade in tandem with DUNE/LBNF operation. The first phase of ACE, is the ACE Main Injector Ramp and Targetry upgrade, would raise the LBNF beam power from 1.2 MW to 2 MW by shortening the Main Injector cycle time to around 0.65s. The second phase of ACE, the ACE Booster Replacement, would replace the Booster with a new machine and achieve 2.4 MW for DUNE/LBNF. The core accelerator challenges, present and future, for operating intense neutrino beams at Fermilab will be highlighted.

MOA3I3	High-Power Targetry and the IMPACT Initiative at Paul Scherrer Institute	30
	D.C. Kiselev PSI, Villigen PSI, Switzerland
	The main challenges to operate a high-power target are dissipation of the heat and radiation damage. The latter refers to the damage of the material. Since the breakdown of the material depends on the operation temperature and other conditions, like the material treatment before irradiation, it is difficult to predict. To reduce failures, target operation parameters and beam properties have to be monitored carefully. After the failure of the neutron spallation target (SINQ) in 2016, several improvements in the HIPA (High intensity Proton Accelerator) beam line at PSI and the target installation were implemented. However, MW beams are not a prerequisite for the need of high power targets. This is the case at one of the two new target stations within the IMPACT initiative at PSI. One target station will produce radionuclides for research in cancer therapy, while the other will improve the surface muon rate by a factor of 100 for experiments in particle and material physics. In this presentation, strategies for successful operation of high-power targets are shown. Furthermore, the IMPACT initiative at PSI, with focus on the two planned target stations, will be presented.
