K29.00001: Meeting high expectations: How ESS will provide unprecedented opportunities for materials research Invited Speaker: Helmut Schober The European Spallation Source (ESS) is Europe's answer in the continuous strive for the production of neutron beams of ever higher brilliance. The scientific instruments exploiting these beams are an indispensable tool for studying material properties as well as transformation processes, which will unlock new discoveries . During my talk I will illustrate the breadth and impact of science performed with neutrons via a few recent examples. The concept underlying the ESS combines a powerful linear accelerator using a 62 mA proton beam and that in its final stage will be delivering a 5 MW long-pulse proton beam to a highly innovative spallation solid tungsten target and a low-dimensional moderator assembly. A suite of initially 15 instruments is designed to exploit the full potential of the long-pulse nature of the neutron beam. In my talk I will present the fundamental design of the accelerator and neutron source followed by an overview of the beam shaping and detection concepts retained to match the instruments optimally to the source characteristics. I will outline the exceptional scientific opportunities created by the unparalleled performance of these instruments and will finish with an update of the current project status. |

K29.00003: The European XFEL: new scientific opportunities and first results Invited Speaker: Sakura Pascarelli In the past decade we have seen very important developments in the field of accelerator based X-ray user facilities, with the advent of 4th generation synchrotron sources and MHz rate hard X-ray free electron lasers (FEL). Among the latter, the EuXFEL is the first hard XFEL powered by a superconducting linear accelerator, which enables MHz rate pulse generation, leading to an increase of more than 2 orders of magnitude in the number of delivered photon pulses per second to the sample. A unique feature of X-ray FELs is the combination of the extremely short (fs) photon pulses with the short (Ȧ) wavelengths of hard x-rays produced. These new user facilities are opening novel avenues in the investigation of fundamental processes in many areas of science, from physics to chemistry, biology and materials science, because they allow investigation of matter at the time scales of electron and nuclear dynamics (down to fs), with chemical selectivity and bulk sensitivity. |

K29.00004: Science at J-PARC Invited Speaker: Takashi Kobayashi J-PARC, Japan Proton Accelerator Research Complex, is the research facility with high intensity proton accelerators which consists of a chain of three accelerators, ie, 400MeV LINAC, 3GeV Rapid Cycling Schinchrotron (RCS), and 30GeV main ring, and three experimental facility, ie, Material & Life Science Experimental Facility (MLF), Hadron Experimetanl facility (HEF), and Neutrino experimental facility. The RCS provides 3GeV proton beam to MLF to produce muon and neutron beam and MR provides the 30GeV proton beam to HEF and neutrino facility. The original design intensity of the accelerators are 1MW and 750kW for RCS and MR, respectively. J-PARC is an unique accelerator facility in the sense that it covers very wide research fields ranging from elementary particle physics, nuclear physics, material and life science, and even, industrial applications. In my presentation I will introduce the latest status of J-PARC accelerators and facilities, recent scientific outcomes, and future plans. |

K29.00005: Science enabled by NSLS-II and possible upgrade paths beyond MBAs Invited Speaker: John P Hill In this talk, I will discuss recent results from the National Synchrotron Light Source II. Commissioned in 2015, this 3GeV, low emittance facility has rapidly ramped up accelerator and beamline operations, presently running at 400 mA with 28 operational beamlines. I will highlight recent research enabled by beamlines delivering world-leading energy and spatial resolution, as well as state-of-the-art autonomous operation. Research includes work on quantum materials, energy storage and COVID-19. Finally, I will conclude with a discussion of potential upgrades to the NSLS-II lattice that would increase the brightness up to a hundred-fold at 10 keV |
