        A mass-measurement of 137-Cs in biological samples 15m
        The present work reports on a citizen science project which is in progress during the autumn 2018. 240 secondary school classes (pupils of age 13-16) participate by collecting mushrooms, soil samples and animal droppings and perform preliminary analyses before submitting their samples and results to Uppsala University (UU) and the Swedish University of Agricultural Sciences (SLU) for further compilation and analysis Scientifically, the project deals with radioactivity accumulated in the environment. In Sweden, the Chernobyl accident in 1986 together with fallout from nuclear tests in the 50s and 60s, have left radionuclides in the environment and some of them can still be found in food (such as game and mushroom) consumed by humans. Measurements of the most significant radionuclide, 137-Cs, was undertaken by the Swedish Radiation Authority after the Chernobyl accident, and since then measurements have been performed at irregular intervals. Recently, the topic of measuring more frequently and coordinately has gained new attention, as meat from wild boars have been found to have high levels of 137-Cs. Wild boars were rare in the Swedish fauna in the 80s; but have since then established a solid population in southern Sweden. The relationship between how the concentration of 137-Cs was in 1986 and how it is today is not straightforward. Biological systems interact with, and redistribute, materials in an efficient manner, and consequently the distribution of the 137-Cs concentrations will be affected. Also, the forest type, soil type, land use, precipitation, hydrology and other environmental factors play significant roles in how the 137-Cs is redistributed. We therefore conclude that more measurements of the presence of 137-Cs in the Swedish environment would be of interest both for several scientific disciplines and for the general public. In this project, gamma radiation from the samples collected by school pupils will be measured carefully with a HPGe detector. In order to facilitate fast and accurate measurements, one must take into account samples that are extended, inhomogeneous, and vary in mass, form, size and composition. We will here report on the ongoing work to set up a detector and analysis environment that can perform a measurement of up to 500 biological samples in a time frame of 2-3 months. The tight time frame is part of the citizen science idea; our public collaborators need feedback on their samples not too long into the future. However, the large amount of samples and data collected opens possibilities for interesting interdisciplinary research long after the school-project is reported and finished. The long-term scientific goal is to create a geodatabase with the 137-Cs activity (Bq/m2) present in the Swedish environment, where radioactivity data also can be linked to the biological species (fungi, competing species, animals foraging), forest type, soil parameters and other environmental factors. To this end, there are many research questions about the role of 137-Cs in ecology and biological food chains that can be investigated.

        Neutron Scattering Instruments and Detectors at the ESS 15m
        The European Spallation Source, ESS, is a facility for material study by means of thermal neutron scattering, currently under construction in Lund, Sweden. The facility broadly consists of a linear accelerator with a 5MW ultimate power, a neutron source based on a spallation target, and a suite of instrument, each optimised for a particular type of investigation. Some instruments will access energy states in soft or condensed matter, others will investigate crystal structure of new materials, while others still will study behaviours of thin layers. These are only a few examples of the applications that the initial suite of instruments will address. Further instruments are envisaged beyond the initial 15, including a fundamental physics beam line for experiments such as neutron decay and neutron - antineutron oscillations. The facility construction is now well underway. Most of the instruments are in the detailed design phase and the first hardware is beginning to take shape. I will present the main classes of the neutron scattering instruments that are being built as well as the types of neutron detectors being used and developed for the ESS and other facilities of this type.

        New ideas on EFT approach to nuclear system 15m
        Recent development of applying chiral effective field theory (EFT) potential on nuclear structure calculation has gained huge success in terms of describing data. However, it also faces problems such as sensitivity to the input data and cutoff. More fundamentally, there is an ongoing debit on whether EFT is lost in the current framework. In this talk the shortcomings of current approach will be discussed, and ideas of an improved version of obtaining interaction from chiral EFT will be introduced.

        Simulation study of the pbar p -> Sigmabar Lambda channel at PANDA 15m
        At PANDA, strangeness production through $\bar{p}p$ $\rightarrow$ Hyperon Antihyperon processes will be addressed. Measurements of the $\bar{p}p\rightarrow \bar{\Sigma} \Lambda $ channel for its comparison with the existing data of the $\bar{\Lambda}\Lambda$ channel are highly encouraged to study the role of isospin symmetry in hadron production dynamics. A previous simulation study from 2009 was performed with a simplified MC framework and an isotropic Sigmabar distribution. However, it has been found by the PS185 that the Sigmabar distribution is very strongly peaked in the forward direction with respect to the beam. In this talk, the motivation for performing a new, more realistic simulation study using the upgraded PandaRoot software and an angular distribution parametrization based on the experimental data will be presented.

        Microscopic description of energy partition in fission 15m
        We describe induced fission and how the resulting fission fragment mass distributions depend on the energy of the incoming neutron. The Metropolis walk method is extended to allow predictions of how the available excitation energy at scission is partitioned between heavy and light fission fragments. From the excitation energy distributions one can deduce how many neutrons that will be emitted from each fragment and how it depends on the energy of the incoming neutron. Compared to earlier studies, we simulate the full fission process taking into account all different fragments and their departure from equilibrium deformations. For each of the fragments we calculate microscopic level densities by solving pairing equations for billions of excited states. The microscopic level densities are used both in the energy partition as well as in the neutron emission.

        The proton structure: Interplay between partonic and hadronic degrees of freedom 15m
        The dbar-ubar asymmetry observed in the proton sea is difficult to understand from a strict perturbative QCD point of view. We show that by also taking into account hadronic (baryon-meson) fluctuations of the proton, this problem has a natural solution and quantitative agreement with data is presented. An outstanding problem going back several decades is the so-called `proton spin puzzle'. This relates to the fact that data shows that the fraction ∆Σ of the proton's spin carried by its constituent quarks is quite small compared to what is predicted by the otherwise successful SU(6) quark-model of hadrons. We present our Hadron-Cloud Model taking into account hadronic and partonic degrees of freedom, relativistic effects and allow for SU(6) symmetry-breaking. With this we obtain good agreement with the polarized structure functions of both the proton and that of the neutron. The measured integrals of the polarized structure functions (and the related Bjorken sum-rule) are also reproduced. This yields a value of ∆Σ consistent with data.

        State-of-the-art and physics research opportunities in ion beam therapy 40m
        Owing to the favorable physical and biological properties of swift ions in matter, their application to radiation therapy for highly selective tumour treatment is rapidly spreading worldwide. To date about 70 ion therapy facilities are treating patients, predominantly with proton beams, and about the same amount is under construction or planning. In Germany, already 3 proton therapy facilities and 2 combined proton and carbon ion beam therapy centers are operational. Over the last decades considerable developments have been achieved in accelerator technology, beam delivery and medical physics to enhance conformation of the radiation dose to complex shaped tumour volumes, with excellent sparing of surrounding normal tissue and critical organs. Nevertheless, full clinical exploitation of the ion beam advantages is still challenged especially by uncertainties in the knowledge of the actual dose delivery during the fractionated course of treatment, thus calling for continued multidisciplinary research in this rapidly emerging field. This talk will review the state-of-the-art in ion beam therapy, giving particular emphasis to remaining challenges with related opportunities for a broad spectrum of ongoing physics-based research activities, spanning from computational modeling to detector developments and imaging methods for beam characterization and in-vivo visualization.

        Isomeric yield ratios in fission for odd mass $^{119-125}$Cd and $^{119-127}$In isotopes with the Phase-Imaging Ion-Cyclotron-Resonance technique 15m
        Measurements of isomeric yield ratios can provide important information about the angular momentum of the fission fragments, whose origin is still one of the many open questions regarding the fission process. Although it is well established that they carry considerable amount of angular momentum, there are competing theories on how this is generated. We will report the first systematic study of independent isomeric yield ratios for the odd mass isotopes of $^{119-127}$In, $^{119-125}$Cd, performed at the Ion Guide Isotope Separator On-Line facility at the University of Jyväskylä using the JYFLTRAP Penning trap. From the experimentally determined isomer production ratios the root-mean-square angular momenta ($J_\mathrm{rms}$) of the initial fission fragments after scission were estimated using the nuclear reaction code TALYS. The study provide important information on how Jrms evolve with respect to the mass number A, approaching the closed neutron shell configuration ($N = 82$). The measurements were possible thanks to a novel approach based on the projection of the Penning Trap ion motion onto a position-sensitive detector. The new Phase-Imaging Ion-Cyclotron-Resonance (PI-ICR) technique, recently implemented at JYFLTRAP, provides a superior mass resolving power, where isomers with excitation energies down to 50 keV can be readily separated from the ground state. In this presentation we describe the PI-ICR method as well as the results and our conclusions.

        From sticky analysis to fast VME shadows 15m
        Storing long-lived slow control information directly in the data stream simplifies analysis, particularly during experiment setup and calibrations. Typical examples are to correlate event-wise data with magnet currents, high-voltage values or thresholds. Sticky events are meant to realise this. Their distinctive feature is that they are valid until revoked or replaced. The status of implementation in the generic UCESB raw data unpacker will be presented. Experiments often do not reach the limits imposed by hardware. In the quest for more statistics, a scheme to use existing commercial multi-event VME modules to their conversion time limit has been implemented. Conversion times below 10 us correspond to accepted event rates above 100 kHz. These are continuously handled as long as the data volume is within the transfer bandwidth of the VME processor. This asynchronous readout mode will be briefly reviewed.

        NUSTAR Data Acquisition: Realizing Signal Exchange Points 15m
        The NUSTAR Data Acquisition System (NDAQ) will provide a data acquisition infrastructure for the foreseen NUSTAR experiments. While all of those experiments require correlated data from detectors located at Super-FRS focal planes, they are very different in terms of used detectors and are in general set-up at different locations along the beam lines downstream from the Super-FRS. In order to distribute trigger signals to the needed locations in a flexible way, a network based on fiber-optics and so-called Signal Exchange Points will be built. The goal to is to be able to configure NDAQ, for a given experiment, in a way that data from all detectors of interest can be correlated as needed, while trigger signals can be generated based on coincidences in experiment and Super-FRS detectors as desired. Commercially available electronics does not meet the SEP specifications, which is why we are currently working on the detailed specification and production of appropriate modules. The hardware concept for SEPs will be presented and discussed.
