  Nowadays project RISP is developed in IBS, Daejeon. One of the main project devices is graphite targets system meant for production of rare isotopes by means of the in-flight fragmentation (IF) technique. The power inside the target system deposited by the primary beam with energy of 200 MeV/u is estimated to be around 100 kW. The target represents rotating multi-slice graphite disc cooled by thermal radiation. Necessary step of the target development is integrated test of target prototype under high power electron beam modelling real energy deposit into target. This test is planned to be held in BINP, Novosibirsk, with the use of ELV-6 accelerator. This paper presents the design of experimental facility as well as experimental program of test. Specifications of electron beam (energy close to 800 keV, size ~ 1mm, total power 30-40 kW) are discussed. Parameters and design of basic devices and systems of facility are described.

  Nowadays project RISP is developed in IBS, Daejeon. One of the main project device is graphite target system meant for production of rare isotopes by means of the in-flight fragmentation (IF) technique. The power inside the target system deposited by the primary beam with energy of 200 MeV/u is estimated to be around 100 kW. The target represents rotating multi-slice graphite disc cooled by thermal radiation. Necessary step of target development is integrated test of target prototype under high power electron beam modelling real energy deposit into target. This test is planned to be held in BINP, Novosibirsk, with the use of ELV-6 accelerator. Heavy-ion beam will be modelled by the e- beam of ELV-6 accelerator with diameter down to ~1 mm and energy 800 keV (minimum possible). IF target is not full stopping target for an electron beam with energy 800 keV. Considerable part of beam energy will be not absorbed by a target material and must be deposited into special beam dump. In this paper the design of beam dump of the graphite cone geometry cooled by thermal irradiation is described.
