	To get a luminosity level of 10³³ cm^-2 s^-1 at all design points of the MEIC, small transverse emittance is necessary in the ion collider ring, which is achieved by an electron cooling. And for the electron cooling, two solenoids are used to create a cooling environment of temperature exchange between electron beam and ion beam. However, the solenoids can also cause coupling and matching problem for the optics of the MEIC ion ring lattice. Both of them will have influences on the IP section and other areas, especially for the beam size, Twiss parameters, and nonlinear effects. A symmetric and flexible method is used to deal with these problems. With this method, the electron cooling section is merged into the ion ring lattice elegantly.

	D. Barker, C. Dimopoulou, C. Peschke GSI, Darmstadt, Germany L. Thorndahl CERN, Geneva, Switzerland
	We report on the design of a Faltin type pickup for the stochastic pre-cooling of rare isotope beams at 740 MeV/u, using a bandwidth of 1-2 GHz, for the Collector Ring (CR) in the FAIR project at GSI. The design difficulties inherent in Faltin rails at these frequencies are described. Measurements of prototypes and HFSS simulations are compared, to check the simulations, and show good agreement. The pickup impedance and signal output phase with respect to ions traveling at 0.83c are simulated and presented for the final design both with and without the use of damping material, showing the need to damp unwanted modes present in the beam chamber.
