  For heavy-ion accelerator facilities charge stripping is a key Technology: the stripping charge state, its efficiency to produce ions in the required charge state, and the beam quality after stripping substantially determine the entire accelerator performance. Modern heavy ion accelerator facilities such as the future Facility for Antiproton and Ion Research (FAIR) at GSI provide for high intensity heavy ion beams beyond 200 MeV/u. Heavy ion stripping at a lower energy enables more efficient acceleration up to the final beam energy, compared to acceleration of ions with a low charge state. Due to the high power deposited by the heavy ions in the stripping media and radiation damages if a solid target is used, self-recovering stripper media must be applied. General implementation options for different stripper target media are discussed in this paper, as well as general considerations to optimize the Linac layout through the appropriate choice of stripping medium and stripping energy. The driver Linac for the Dubna Electron-Radioactive Isotope Collider fAcility (DERICA) project, recently initiated by JINR, is foreseen to provide for 100 MeV/u Uranium beam in continuous wave mode. First layout scenarios of a one-step and a two-step DERICA-stripper approach will be also presented.
