  We report on the preliminary design of Slot-ring and Faltin type pickups and kickers for stochastic pre-cooling of rare isotope beams from 625 MeV/u to 840 MeV/u (\beta: 0.80-0.85), or from 400 MeV/u to 625 MeV/u (\beta: 0.71-0.80), using a bandwidth of 1-2 GHz (or 0.6-1.2 GHz) for Spectrometer ring (Sring) in the HIAF project at IMP. The kicker shunt impedance and signal output phase of Slot-ring and Faltin type are calculated by HFSS. From the simulation results, Slot-ring structure is better for higher \beta (0.80-0.85), and Faltin type will be a better choice for \beta from 0.71 to 0.80 when the beam aperture is 200 mm*120 mm.
