A Storage Ring Experiment to Detect a Proton Electric Dipole Moment

A new experiment is described to detect a permanent electric dipole moment of the proton with a sensitivity of $10^{-29}e\cdot$cm by using polarized "magic" momentum $0.7$~GeV/c protons in an all-electric storage ring. Systematic errors relevant to the experiment are discussed and techniques to address them are presented. The measurement is sensitive to new physics beyond the Standard Model at the scale of 3000~TeV.

RHIC Low-Energy Challenges and Plans

There is significant interest in RHIC heavy ion collisions at $\sqrt{s_{NN}}=$5--50 GeV, motivated by a search for the QCD phase transition critical point. The lowest energies for this search are well below the nominal RHIC gold injection collision energy of $\sqrt{s_{NN}}=19.6$ GeV. There are several operations challenges at RHIC in this regime, including longitudinal acceptance, magnet field quality, lattice control, and luminosity monitoring. We report on the status of work to address these challenges, including results from beam tests of low energy RHIC operations with protons and gold, and potential improvements from different beam cooling scenarios.

Crystal-based approach to beam collimation in RHIC and SNS

Bent crystal serving as a scraper of the beam collimation system can channel halo particles directly into the absorber. By means of computer simulations, we analyse the capabilities of crystal technique for the beam cleaning process. Two applications are considered: the crystal collimator now being installed into RHIC for cleaning of the fully stripped gold ions, and a similar system being developed for the Accumulator Ring of the Spallation Neutron Source.

A Prototype of the UAL 2.0 Application Toolkit

The paper presents a prototype of the accelerator commissioning and simulation application toolkit based on the Unified Accelerator Libraries (UAL) framework. The existing UAL 1.x environment has been implemented as an open collection of C++ and Perl packages that address various tasks of accelerator physics. The UAL 2.0 application toolkit has been developing on the top of the Java infrastructure for integrating it with distributed accelerator control systems. The core part of the toolkit is composed of the Common Accelerator Objects (such as Accelerator, Algorithms, etc.) that form the framework for developing project-specific applications. The toolkit environment is not only limited to Java applications, but also supports the development and integration of high-level scripting codes (e.g. Java Python scripts) and existing C/C++ libraries. The configuration and navigation of the project-specific application system is provided by the XML-based Application Manager.
