A new experiment is described to detect a permanent electric dipole moment of the proton with sensitivity $10^{-29}e\cdot$cm by using polarized "magic" momentum $0.7$~GeV/c protons in an all-electric storage ring. Systematic errors relevant are discussed and techniques address them presented. The measurement sensitive physics beyond Standard Model at scale 3000~TeV.
This document summarizes the work of Accelerator Working Group (AWG) International Scoping Study (ISS) a Future Neutrino Factory and Superbeam Facility. The main goal activity was to reach consensus on baseline design for complex, including proton driver parameters, choice target, front-end design, acceleration system decay ring geometry. Another explore commonality, if any, between those or Beta Beam facility. In general, requirements either latter facilities are less stringent than...
We report initial results of exposing low-Z solid and high-Z liquid targets to 150-ns, 4/spl times/10/sup 12/ proton pulses with spot sizes on the order 1 2 mm. The energy deposition density approached 100 J/g. Diagnostics included fiberoptic strain sensors target high-speed photography targets. This work is part R&D program Neutrino Factory Muon Collider Collaboration.
In search of a low-Z pion production target for the Long Baseline Neutrino Facility (LBNF) Deep Underground Experiment (DUNE) four graphite grades were irradiated with protons in energy range 140--180 MeV, to peak fluence $\ensuremath{\sim}6.1\ifmmode\times\else\texttimes\fi{}{10}^{20}\text{ }\text{ }\mathrm{p}/{\mathrm{cm}}^{2}$ and irradiation temperatures between $120--200\text{ }\ifmmode^\circ\else\textdegree\fi{}\mathrm{C}$. The test array included POCO ZXF-5Q, Toyo-Tanso IG 430,...
The NT-02 neutrino physics target made of the isotropic graphite grade produced neutrinos for MINOS and MINERVA high-energy experiments. segmented, 95-cm-long was bombarded with a 340 kW, Gaussian 1.1 mm sigma beam 120 GeV protons reaching $6.516\ifmmode\times\else\texttimes\fi{}{10}^{20}$ on peak fluence $8.6\ifmmode\times\else\texttimes\fi{}{10}^{21}\text{ }\text{ }\mathrm{protons}/{\mathrm{cm}}^{2}$. Reductions in detected events during experiment were attributed to radiation-induced...
The effects of proton beams irradiating materials considered for targets in high-power accelerator experiments have been studied using the Brookhaven National Laboratory's (BNL) 200 MeV linac. A wide array and alloys covering a range atomic number (Z) are being scoped by community prompting BNL studies to focus on representing each distinct range, i.e. low-Z, mid-Z high-Z. low includes such as beryllium graphite, midrange Ti-6Al-4V, gum metal super-Invar finally high-Z pure tungsten...
A high-strength dual alpha+beta phase titanium alloy Ti-6Al-4V is utilized as a material for beam windows in several accelerator target facilities. However, relatively little known about how properties of this are affected by high-intensity proton irradiation. With plans to upgrade neutrino facilities at J-PARC and Fermilab over 1 MW power, the radiation damage window will reach few displacements per atom (dpa) year, significantly above ~0.3 dpa level existing data. The RaDIATE collaboration...
Large, deep, well shielded liquid detectors have become an important technology for the detection of neutrinos over a wide dynamic range few MeV to TeV. The critical component this is large format semihemispherical photo-multiplier tube with diameters in 25 50 cm. survival assembled array these tubes under high hydrostatic pressure subject study. These are results from R&D program which intended understand modes failure when implodes pressure. Our tests include detailed measurements shock...
Next-generation synchrotron accelerator facilities pushing the envelope of resolution to just a few nanometers and possibly atomic scale (~1 nm) require extreme stability their experimental sett...
In many high energy physics neutrino beamlines, targets are made up of isotropic POCO graphite grade for production neutrinos particle research and bombarded with highly energetic pulsed proton beam. The beam a small size creates thermal stress waves as well radiation damage such displacement damage, void formation, swelling, gas formation amongst others. As result, after few years operation one the longest operated appears to have undergone bulk swelling fractured along centerline. A...
