In recent neutron production operations at SNS, beams contaminated the longitudinal extraction gap of the accumulator ring due to the limitation of the beam choppers. It caused significant beam loss and activation in the ring and in the extraction beam line. From simulations with computer models and in experimental measurements, properly utilizing the ring RF systems with additional storage turns after the beam accumulations in the ring effectively reduced beam loss in the SNS accelerator systems. Simulations and beam measurement results will be discussed

The Metrology Light Source (MLS) is dedicated to metrological and technological developments in the UV and EUV spectral range and in the IR and THz region. The new electron storage ring of the Physikalisch-Technische Bundesanstalt (PTB) is located next to the BESSY II storage ring in Berlin - Adlershof. The MLS with its 48 m circumference can be operated at any electron beam energy between 105 MeV and 630 MeV. The electron beam currents vary from 1 pA (one stored electron) up to 200 mA. These specific modes of operation were achieved during the initial one year phase of the commissioning of the storage ring until April 2008, when the regular MLS user operation started. The basis for this success was the previously commissioned microtron which is the main part of the injection system.

An intense neutron source with emittance recovery internal target (ERIT) using ionization cooler ring has been developed at Kyoto University Research Reactor Institute (KURRI) for boron neutron capture therapy (BNCT). The neutron source consists of a 11MeV H- linac and a FFAG storage ring. A thin (10micron) Be target is placed in the ring. In order to reduce an emittance growth caused by multiple scattering at the target, an ionization cooling with a low frequency and high voltage RF cavity is utilized. The beam is expected to be survived for more than 500 turns in the ring, which can increase beam efficiency largely to reduce an injected beam current.
