Project Status of the Polish Synchrotron Radiation Facility Solaris

Abstract in Undetermined The Polish synchrotron radiation facility Solaris is being built at the Jagiellonian University in Krakow. The project is based on an identical copy of the 1.5 GeV storage ring being concurrently built for the MAX IV project in Lund, Sweden. A general description of the facility is given together with a status of activities. Unique features associated with Solaris are outlined, such as infrastructure, the injector and operational characteristics

Towards Specification of Tango V10

International audienceMore than 40 laboratories use Tango Controls as a framework for their control systems. During its 18 years of existence, Tango Controls has evolved and matured. The latest 9.3.3 release is regarded as the most stable and feature-reach version of the framework. However, it makes use of already outdated CORBA technology which impacts all the stack, from the low-level transport protocol up to the client API and tools. The Tango Community decided to move forward and is preparing for so-called Tango Controls v10. Tango v10 is meant to be more a new implementation of the framework than a release of new features. The new implementation shall make the code easier to maintain and extend as well as remove legacy technologies. At the same time, it shall keep the Tango Controls objective philosophy and allows the new implementation to coexist with the old one at the same laboratory. The first step in the process is to provide a formal specification of current concepts and protocol. This specification will be base for the development and verification of new source code. Formal specification of Tango Controls and its purpose will be presented along with used tools and methodologies

Towards Improved Accessibility of the Tango Controls

International audienceTango Controls is successfully applied at more than 40 scientific institutions and industrial projects. These institutions do not only use the software but also actively participates to its development. The Tango Community raised several projects and activities to support collaboration as well as to make Tango Controls being easier to start with. Some of the projects are led by S2Innovation. These projects are: gathering and unifying of Tango Controls documentation, providing a device classes catalogue and preparation of a so-called TangoBox virtual machine. Status of the projects will be presented as well as their impact on the Tango Controls collaboration

Tango Controls RFCs

International audienceIn 2019, the Tango Controls Collaboration decided to write down a formal specification of the existing Tango Controls protocol as Requests For Comments (RFC). The work resulted in a Markdown-formatted specification rendered in HTML and PDF on Readthedocs.io. The specification is already used as a reference during Tango Controls source code maintenance and for prototyping a new implementation. All collaborating institutes and several companies were involved in the work. In addition to providing the reference, the effort brought the Community more value: review and clarification of concepts and their implementation in the core libraries in C++, Java and Python. This paper summarizes the results, provides technical and organizational details about writing the RFCs for the existing protocol and presents the impact and benefits on future maintenance and development of Tango Controls

Temperature-dependent orientation of self-organized nanopatterns on ion-irradiated TiO_{2}(110)

none10Temperature-dependent self-organized formation of nanoripples on TiO2(110) surfaces irradiated by low-energy Ar+ beams has been investigated by scanning tunnelling microscopy in UHV conditions. Under the experimental conditions employed (2 keV Ar+ and oblique incidence, 75∘ off-normal, T = 120, 300, 620, and 720 K) on the irradiated surface the ripple structure of periodicity ∼10 nm has developed. Interestingly, the orientation of the nanopatterns switches reversibly by 90∘ with the systematic change of the substrate temperature during irradiation. We have demonstrated that formation of the surface nanomorphology is determined by the interplay between the erosion of the monatomic step edges at grazing incidence, anisotropic surface diffusion along the favoured crystallographic orientation and, at elevated temperatures, the diffusion into the bulk of the excess Ti ions. As indicated by density functional theory (DFT) calculations used for modelling the diffusion processes on the ion irradiated TiO2(110), the significant surface mass transport required to form the nanoripples is dominated by the highly mobile Ti atoms diffusing in assistance of O adatoms.M.
