High precision X-ray measurements 2020

Overview High Precision X-ray Measurements 2020 conference is the second edition of the HPXM2018 workshop, held at the INFN Laboratories of Frascati in 2018. In the wake of the big success of the previous edition, HPXM2020 is planned both to consolidate the existing interconnections between different research teams and to help creating new ones, creating the opportunity for all the participants to discuss and share the results of their activities focusing on a common protagonist: X-ray precision detection.  The aim of this workshop is to update the participants on the most recent developments in X-ray detection and their possible impacts in various sectors like, nuclear physics, quantum physics studies, XRF, XES, EXAFS, PIXE, plasma emission spectroscopy, monochromators, synchrotron radiation, telescopes and space engineering, medical applications, food and beverage quality control and elemental mapping. In the HPXM2020 edition, also the topics of radioprotection and X-ray tracing simulations will be covered with dedicated sessions. A special focusing will also devoted to graphite mosaic crystals and their applications. The scientific program consists of invited lectures from distinguished scientists, oral presentations given by the participants technical presentations given by the sponsors, which will be also present for the whole conference duration with fixed stands to show their latest products. Main Topics: X-ray energy detectors X-ray position detectors Spectrometers X-ray tracing simulations Radioprotection X-ray optics Graphite based applications X-ray imaging Cultural heritage applications of X-rays X-rays in astrophysisc Medical applications X-rays in nuclear physics Best presentation award: A best presentation contest will take place to ...

8th Low Emittance Rings Workshop (New Dates!)

The 8th Low Emittance Rings Workshop will be held in Frascati, INFN-LNF on 26-28 October 2020, supported by the ARIES project. The goal of the workshop is to bring together experts from the scientific communities working on low emittance lepton rings. The workshop is sponsored by the RULE network under the ARIES European project and includes light source storage rings, linear collider damping rings and future e+/e- circular colliders. The theme will be beam dynamics and technology challenges for producing and controlling ultra‐low emittance beams and the participants will benefit from the experience of colleagues who have designed, commissioned and operated such rings. Workshop sessions will include: ‐ Low Emittance optics design and tuning (LERD) – Collective Effects and beam instabilities (IICE) – Low Emittance Ring Technology (LERT) Students are encouraged to participate. A Student Poster Session is forseen starting on the first Workshop day. A prize will be awarded to the best student presentation to allow the participation in a major conference presenting works related to Low Emittance Rings. The programme will be organised by the Scientific Programme Committe: Maher Attal, SESAME Ryutaro Nagaoka, SOLEIL Riccardo Bartolini, JAI & Diamond Light Source Yannis Papaphilippou, CERN – Chair Gabriele Benedetti, ALBA Qing Qin, IHEP Mike Borland, ANL Victor Smalyuk, BNL Susanna Guiducci, INFN-LNF Andreas Streun, PSI Robert Hettel, SLAC Rainer Wanzenberg, DESY Emanuel Karantzoulis, ELETTRA Simon White, ESRF Simon Leeman, LBNL Frank Zimmermann, CERN Akira Mochihashi, KIT                                                                                                                       ************************** Proposals for contributions to the workshop could be addressed ...

Fourth Rome Physics Encounter @LNF

The encounter is postponed until further notice following the restrictions from INFN regarding organised meetings.   This informal meeting is the fourth of the Rome physics encounter series. It aims at bringing together young speakers working or collaborating with the research groups in the Rome area. In the spirit of workshops and conferences at LNF, talks will be presented in a pedagogical way and plenty of time is scheduled to allow discussions among participants. The encounters will be synchronised with a selected LNF General Seminar, held in the afternoon at 2.30pm. The lunch is offered to all registered participant at the LNF canteen.

Universal Rainbow Channeling Potential

The problem of an accurate ion-solid interaction potential is one of the basic problems in description of the ion-solid interaction [1]. It has been shown how one can construct the universal rainbow channeling proton-crystal interaction potential [2]. It has been done by modifying the Moliere’s interaction potential applying the crystal rainbow theory [3, 4]. This potential merges the ZBL potential, for the small impact parameters, and the Molière’s potential, with the Thomas-Fermi radius, for the large impact parameters. The accuracy of the obtain interaction potential should be investigated in a series of high resolution transmission channeling experiments for different proton-crystal combinations. Further, application of the presented rainbow morphological method for 5 keV protons transmitted through a graphene [5] and generally through 2D materials has been disused. [1] M. Nastasi, J. W.

Machine learning an unknown physical law: the structure of the proton

Machine learning techniques are increasingly used for recognizing pattern and devising optimal strategies: situations in which the machine is taught (or teaches itself) to learn a known correct answer, or the best use of known rules. In particle physics, machine learning has been used now for several years  in order to determine an underlying physical law which is known to exist, but which is unknown. Furthermore, because elementary particles are quantum objects, this law is stochastic in nature: the machine has to learn a probability distribution, rather than a unique answer. I will discuss some classic results, used among others in the discovery of the Higgs boson, as well as recent developments, which raise the fundamental question of how to decide whether an answer is correct.
