February 6, 2013  The editors of the APS journals have selected 142 new Outstanding Referees for 2013, out of more than 60,000 currently active referees. Initiated in 2008, the highly selective Outstanding Referee program recognizes scientists who have been exceptionally helpful in assessing manuscripts for publication in the APS journals. Selections are based on two decades of records on the number, quality, and timeliness of referee reports. The 2013 honorees come from 27 different countries, with large contingents from the US, Germany, UK, Canada, and France. The decisions were difficult and there are many excellent referees who have yet to be recognized. By means of the program, APS expresses appreciation to all referees, whose efforts in peer review not only keep the standards of the journals at a high level, but in many cases also help authors to improve the quality and readability of their articles—even those that are not published by APS. For more information and a listing of all Outstanding Referees, please visit http://publish.aps.org/OutstandingReferees.

In order to find electron sources of low emittance and high quantum efficiency, single tip cathodes with a microstructured surface are investigated. Emission currents up to 310 A were obtained, by combining a 2 ns, 50 kV accelerating voltage pulse with a 266 nm wavelength, picosecond (σt=6.2 ps) la... [Phys. Rev. ST Accel.

The KEK digital accelerator (KEK-DA), which is a small-scale rapid-cycle induction synchrotron (IS), has commenced operation. A permanent magnet x-band electron cyclotron resonance ion source serves as the KEK-DA ion source and delivers various ions. A new Einzel lens beam chopper has been developed... [Phys. Rev. ST Accel.

The principle of using multiple partial helical magnets to preserve the polarization of the proton beam during its acceleration was applied successfully to the alternating gradient synchrotron (AGS) which currently operates with two partial helical magnets. In this paper we further explore this idea... [Phys. Rev. ST Accel. Beams 16, 043501 (2013)] Published Thu Apr 11, 2013

In this study, the observation of three simultaneously rotating beams in the SOLEIL storage ring is reported. This event occurred in November 2007 while operating in a low momentum compaction factor mode. The dynamics of the three beams is simulated using the longitudinal equations of motion and the...

Ion beams (including protons) with low emittance and high space-charge intensity can be propagated with normal incidence through a sequence of thin metallic foils separated by vacuum gaps of order the characteristic transverse beam extent to transport/collimate the beam or to focus it to a small tra...

Flat beams feature unequal emittances in the horizontal and vertical phase space. Such beams were created successfully in electron machines by applying effective stand-alone solenoid fringe fields in the electron gun. Extension of this method to ion beams was proposed conceptually. The present paper... [Phys. Rev. ST Accel. Beams 16, 044201 (2013)] Published Thu Apr 11, 2013

The concept of sharing a high-power proton accelerator (proton driver) between neutrino production and other facilities such as a high-energy collider or a spallation neutron source is an attractive, cost-effective solution which is being studied in site-specific cases as part of accelerator upgrade...
