A DC wire has been installed in RHIC to explore the long-range beam-beam effect, and test its compensation. We report on experiments that measure the effect of the wire's electro-magnetic field on the beam's lifetime and tune distribution, and accompanying simulations.

  We report on simulations of beam-beam experiments performed at RHIC in 2006. These experiments were designed to observe the influence of a single parasitic interaction on beam quality. Several observables such as tunes, emittances and losses were simulated with the weak-strong code BBSIM. These simulation results are compared to observed values. Simulations of the wire compensation experiment to be carried out in RHIC are also shown.

  Funding: This research was supported by MOST (Ministry of Science and Technology) of Korea as a sub-project of PEFP (Proton Engineering Frontier Project).

The test beam line was installed at the MC-50 cyclotron of KIRAMS (Korea Institute of Radiological And Medical Sciences). It has been supporting many pilot and feasibility studies on the development of beam utilization technologies of PEFP (Proton Engineering Frontier Project). The energy measurement with high accuracy is very important for the some experiments such as radiation hardness test of semiconductor devices, nuclear physics, detector test, etc. SSB and Si(Li) detector was used as del-E and E detector and the thickness of detectors are 2mm and 5mm each. The available energy range is 10MeV~39MeV and the flux was controlled not to be exceed 1·10+05/cm2-sec using a 0.5mm diameter collimator.
