	Funding: Work supported by Cooperative Research and Development Agreement (CRADA), No. BNL-C-10^-03 between the Brookhaven National Laboratory and Best Medical International, Inc. We present a design of the ion Rapid Cycling Medical Synchrotron (iRCMS) for carbon/proton cancer therapy facility. The facility design, produced at Brookhaven National Accelerator (BNL) at the Collider Accelerator Division (CAD) for the BEST Medical International, Inc., will be able to treat the cancer patients with carbon, lighter ions and protons. The low energy part accelerates ions and protons to the kinetic energy of 8 MeV. It consists of two ion sources (one of fully stripped carbon ions and one for protons), a Radio-Frequency Quadrupole (RFQ) and linac. The 8 GeV beam is injected into a fast cycling synchrotron (iRCMS). The lattice design is a racetrack, with zero dispersion two parallel straight sections. There are 24 combined function magnets in the two arcs with a radius of ~5.6 meters with maximum magnetic field of less than 1.3 T. The acceleration is performed in 30 Hz up to the required energy for the cancer tumor treatment assuming the spot scanning technique. The maximum energy for carbon ions is 400 MeV. Ions are extracted in a single turn and fed to different beam lines for patient treatment.

	Coherent electron cooling (CEC) is considered to be on of potential candidates capable of cooling high-energy, high-intensity hadron beams to very small emittances. It also has a potential to significantly boost luminosity of high-energy hadron-hadron and electron-hadron colliders. In a CEC system, a perturbation of the electron density caused by a hadron is amplified and fed back to the hadrons to reduce the energy spread and the emittance of the beam. Following the funding decision by DoE office of Nuclear Physics, we are designing and building coherent electron cooler for a proof-of-principle experiment at RHIC to cool 40 GeV heavy ion beam. In this paper, we describe the layout of the CeC installed into IP2 interaction region at RHIC. We present the design of the CeC cooler and results of preliminary simulations.

	We present the design of a future high-energy high-luminosity electron-hadron collider at RHIC called eRHIC. We plan adding 20 (30) GeV energy recovery linacs to accelerate and to collide polarized and unpolarized electrons with hadrons in RHIC. The center-of-mass energy of eRHIC will range from 30 to 200 GeV. The luminosity exceeding 10³4 cm^-2s⁻¹ can be achieved in eRHIC using the low-beta interaction region which a 10 mrad crab crossing. A natural staging scenario of step-by-step increases of the electron beam energy by builiding-up of eRHIC's SRF linacs. We report on the eRHIC design and cost estimates for it stages. We discuss the progress of eRHC R&D projects from the polarized electron source to the coherent electron cooling.
