“…In sum, this allows the running simultaneously of the EPICS/Linux and the LabVIEW Real-Time in the same PXI controller, sharing a common memory block as their communication interface. A control software for the beamline developed in Python at the LNLS (Py4Syn) [10] completes the picture with a practical and intuitive user interface in CS-Studio. These changes were essential preparations for the next upgrades on the beamline.…”

Abstract. The XAFS2 is a general-purpose X-ray absorption beamline. It is the second one built at the LNLS. After approximately 7 years in operation this beamline has been substantially updated in order to improve its experimental possibilities. Recently arrived, a 4-circle Huber diffractometer has been incorporated to perform combined experiments. This collects XRD patterns with the XAFS. Through the development of a new sampling environment it is now also possible to perform these measurements in situ/operando conditions. Other upgrades include a complete remodelling of the beamline software and its control system. The following new systems are crucial for the next steps that are currently underway at the beamline, namely, (i) enabling remote access for users and (ii) the testing of QEXAFS measurements. IntroductionUpon the completion, in 2007, of the commissioned works on the XAFS2 [1], a large number of users have been using this experimental facility in order to perform several kinds of experiments [2][3][4][5]. Since 2007, and with the development of combined simultaneous characterizations [6], there are a plethora of new possibilities additional to the usual XAFS experiments. Among these numerous possibilities; a combined XAFS and XRD experiment would be especially useful in order to obtain structural information of the short range order (around a selected absorber atom) and of the long range order, thus unveiling information on the material as a whole. Here one is probing different properties of the same system in a unique experiment under the same conditions, thus bridging the complex gaps in the structure. Therefore, in order to improve those abilities of the beamline, a 4-circle Huber Diffractometer was added to the experimental hutch in order to explore both techniques [7] through user demand. Here below an example of these XAFS and XRD measurements is presented. The example shows the performance of the beamline at work while combining both techniques.Importantly, the control system of the beamline has been renovated by the installation of a PXI. The PXI is from National Instruments (PXI-NI) and communicates with Galil/Parker controllers on an EPICS platform [8]. Note some parts of the motors were changed in order to improve performance with the upgrade and there were also important changes to the control hardware. The Windows

“…Furthermore, a new python based script (Py4Syn) was added. This provides high-level abstraction for device manipulation, scan routines, real-time plots and more [10]. This package was created with the aim of providing a simple yet powerful tool to allow scientists and users to develop their own scripts for data acquisition.…”

“…The foundation of Mamba, our software framework, is the Python-based Bluesky (Allan et al, 2019); before making the choice, we had researched multiple well-known alternatives for similar applications, like GDA (Gibbons, Heron and Rees, 2011), Sardana (Coutinho et al, 2011), Karabo (Hauf et al, 2019) and py4syn (Slepicka et al, 2015). Here we avoid discussing the details of our choice, and instead note that the choice is not based on the availability of readily usable features, but based on the total efforts needed to adapt the publicly available codebase to our applications.…”

Mamba is a Bluesky-based experiment control framework being developed for HEPS; its frontend and backend collaborate through a RPC service, and most importantly command injection. Improvement of Bluesky's support for high-frequency and high-throughput applications is in progress, with Mamba Data Worker as a key component. Other plans, including an experiment parameter generator and Mamba GUI Studio, are also discussed.

This research consisted of developing a graphical user interface in Python language for the reconstruction of images based on the image-based propagation technique (PBI). The methodology used consisted of rewriting and ordering the existing code by reformulating it in the form of classes and methods to link them to the graphical user interface template using PyQt. The analysis requirements, design, and implementation of user graphic interface were explained. The graphical user interface permitted conducted two experiments using the image-based propagation technique (PBI) and analyzing their differences and similarities, and demonstrating that the algorithm for reconstruction was testing successfully.
