 ::''Abstract'': The capability of accelerating a polarized 3He ion beam in RHIC would provide an effective polarized neutron beam for the study of new high-energy QCD studies of nucleon structure.  This development would be particularly beneficial for the future plans of an Electron Ion Collider, which could use a polarized 3He ion beam to probe the spin structure of the neutron.  The proposed polarized 3He ion source is based on the Electron Beam Ion Source (EBIS) currently in operation at Brookhaven National Laboratory.  3He gas would be polarized within the 5 T field of the EBIS solenoid via Metastability Exchange Optical Pumping (MEOP) and then pulsed into the EBIS vacuum and drift tube system where the 3He will be ionized by the 10 Amp electron beam.  The goal of the polarized 3He ion source is to achieve 2.5 x 10^11 3He++/pulse at 70% polarization.  An upgrade of the EBIS is currently underway.

	::''Abstract'': Crab crossing is an essential mechanism for high-luminosity particle colliders. Several future particle colliders (HL-LHC, EIC, FCC-hh) incorporate crab cavities in their design. The possibilities offered by crab cavities are multiple. Firstly, to reestablish head-on collisions, which maximize the colliding bunches overlap and consequently the peak luminosity. Equally important, crabs provide another mechanism for luminosity levelling by adjusting the crabbing angle as bunches depopulate with every collision. In addition, crabs allow implementing the crab kissing technique which reduces the pile-up density. This talk will discuss the different crab operation modalities and their impact on experimental data quality, present the main motivation behind the adoption of crab cavities by different colliders and provide an overview of the cavity designs being considered for the crabbing systems of these future colliders.		::''Abstract'': Crab crossing is an essential mechanism for high-luminosity particle colliders.
