Description
The High Power Targetry R&D Roadmap for High Energy Physics Workshop is focused upon plotting the course for the HPT R&D activities necessary for supporting the future global High Energy Physics experimental program. A draft workshop charge is below. Please join us as we discuss the targetry challenges of the long-term HEP program, the R&D routes necessary to meet those challenges, and develop a useful R&D roadmap to guide near-term activities.

Workshop Charge: Identify the required and most beneficial High Power Targetry (HPT) R&D routes and associated key milestones, considering the needs, objectives, and timeline of the HEP experimental program as recommended in the 2014 P5 report. The resulting HPT R&D for HEP “roadmap” should plot the course that is suitable for HPT R&D GARD (General Accelerator Research and Development) activities for the next ten years while supporting the objectives of HEP projects in the 10 – 30 year time frame. Synergies with other branches of the DOE Office of Science should be identified and evaluated for potential benefits.

A link to the 2014 P5 report (Particle Physics Project Prioritization Panel) is included in the background materials below.

        High Power Targets at J-PARC (part 1)
        Japan Proton Accelerator Research Complex, J-PARC consists of a series of world-class proton accelerators and the experimental facilities. J-PARC is a multi-purpose facility where the variety of secondary-particle beams are produced and are used in a wide range of scientific fields, such as fundamental nuclear and particle physics, materials and life science, and nuclear technology. Neutron, pion, muon, kaon and neutrino beams are produced through collisions between the high-power proton beams and target materials. Requirement to increase the intensity of the proton beam is getting higher and higher for further advanced researches. Consequently, the thermal load and the irradiation effect to the target materials are also getting severer. Simultaneously, cooling methods to remove the thermal load are restricted by requirements from physics experiment. In this presentation, present status and future prospect of the high-power targets at J-PARC, especially muon target and neutron target at Materials and Life Science Experimental Facility, COMET target at Hadron Experimental Facility, and ADS target at Transmutation Experimental Facility will be introduced.

        "conCERNs" Requirements for CERN’s Beam Intercepting Devices design, operation and R&D
        In the contribution, I will briefly discuss the upcoming CERN Projects and the respective beam requirements. I will then provide examples of challenges related to Beam Intercepting Devices (BIDs), such as target, collimator and absorbers/dump in the LHC as well as in the injector chain. I will focus on few specific devices and systems in order to give practical examples of issues that engineers and physicist need to tackle when designing, building and operating such equipment.

        Increased Neutrino Yield with the New NOvA Target Design: Simulation Study
        NOvA (NuMI Off-axis νe Appearance) is a long baseline neutrino oscillation experiment designed to search for both νe appearance and νμ disappearance. Fermilab NuMI (Neutrinos at Main Injector) facility produces an intense neutrino beam (narrow band νμ beam peaked at 2 GeV in energy with 700kW beam power) colliding 120 GeV protons from the Main Injector into a long target with a set of two magnetic horns (Horn1 and Horn2) to focus the pions produced at the target. We studied different target designs and Horn2 configuration to optimize the neutrino yield. Here, we present the New Target design which increases the νμ yield at the NOvA Far detector by about 21% compared to the event yield with the current NuMI target.

        Production Target Requirements for the Mu2e-II Experiment
        We will propose an evolution of the Mu2e experiment - called Mu2e-II - that would utilize an increased proton intensity to improve the sensitivity for neutrinoless muon-to-electron conversion by one order of magnitude over Mu2e. The proposed upgrade will use as much of the Mu2e infrastructure as possible, but improvements to the Mu2e apparatus necessary to accommodate the increased beam intensity. We will focus here on the pion production target requirements, assuming that we will utilize a proton beam delivered by a CW-capable PIP-II linear accelerator.

        High Power Targetry at FRIB
        The Facility for Rare Isotope Beams (FRIB) currently under construction at Michigan State University will use a 400 kW primary ion beam from a superconducting radiofrequency accelerator for in-flight production of intense beams of radionuclides. This presentation will give an overview of the design / concept and the challenges associated with high power density in the four main equipments impacted by beam in the Experimental System Area: the rotating graphite production target, the high power rotating beam dump based on a water filled drum made of Ti-alloy thin shell, the fragment catcher made of water cooled Al-alloy slits and Al-alloy wedge. This presentation will also discuss developments on how to mitigate some of the issues / challenges.

        High power targets of ILC: Beam dump window and positron target
        The ILC is an electron-positron collider whose energy is 500 GeV in center-of-mass. It has several kind of beam dumps and the maximum, the final beam-dump after IP, has to receive 14 MW of power. The conceptual design of this beam dump had been performed in 2012 by India/US/UK team and a water dump was proposed. It should have a window facing a vacuum of a beam line and and a water as a dump core. In addition, the ILC has another target for positron generation. It receives several kW of deposition by photons from the 300m-long undulator. A study of the positron source is in progress with overseas collaborators. Recently the KEK ILC group formed a team to lead the successive beam-dump studies toward the green light for ILC. We are planning to establish designs in a few years. We would like to introduce our objectives for discussion.
