16. Challenges of Neutrino Targets and the Role of the HiRadMat Facility

Patrick Hurh

Following from the Particle Physics Project Prioritization Panel (P5) 2014 report, Fermilab is hosting a new Long-Baseline Neutrino Facility (LBNF) with greater than one megawatt of proton beam power on target and upgrade potential to greater than two megawatts. As future accelerator neutrino sources, such as LBNF, become increasingly powerful and intense, there is a pressing need to address...

15. Demands for Thermal Shock Experiments of Pulsed-Muon-Production Target Materials

Mr Shunsuke Makimura (J-PARC, KEK)

Muons are widely used for the various fields in condensed matter physics and fundamental nuclear physics. Muons or parent particles, pions are produced by collision of high energy protons against a target material. A pulsed muon beam and a continuous DC muon beam are selectively used for the purpose of the experiments. In particular, the pulsed muon beam is useful for Muon-Spin-Spectroscopy...

35. Interaction of intense proton beam pulses with granular and powdered materials

Chris Densham (Science and Technology Facilities Council STFC (GB)), Peter Loveridge (Science and Technology Facilities Council STFC (GB))

Two experiments conducted at HiRadMat have revealed the disruption of granular and powdered materials by intense proton beam pulses, and that the results are consistent with an electrostatic mechanism. While the initial purpose was to investigate practical issues of concern for granular target technology, these experiments have opened a window onto the behaviour of granular media that we...

38. Technical challenges for higher intensity operation at J-PARC neutrino facility

Takeshi Nakadaira (KEK)

The J-PARC neutrino facility is producing the high intensity muon neutrino beam for the long base-line neutrino oscillation experiment with the conventional method using the 30GeV proton beam from the J-PARC MR accelerator. The neutrino beam-line is originally designed for the proton beam power of 750kW, and the stable neutrino beam production with the 500kW beam power is acieved. The beam...

17. Theoretical modeling for the thermal stability of solid targets in LEMMA muon collider

Dr Gianmario Cesarini (INFN Sezione di Roma)

This work, in the context of the LEMMA project, is aimed at assessing thermal stability and heat dissipation problems of crystalline solids used as targets for the purpose of producing muons. Monitoring the increase in temperature on the target due to the passage of positrons and the consequent energy loss is fundamental in order to keep the target operational and avoid fractures or damage....
