	Em# project is a collaboration project between MAX IV Laboratory and ALBA Synchrotron to obtain a high performant four-channel electrometer. Besides the objective of accurate current measurements down to the pico-ampere range, the project pursues to establish a reusable instrumentation platform with time stamped data collection able to perform real time calculations for flexible feedback implementations. The platform is based on a FPGA responsible of acquisition and synchronization where a real-time protocol between the modules has been implemented (Harmony) []. The data acquired is transmitted via PCIe to a Single Board Computer with an embedded Linux distribution where high level processing and synchronization with upper levels of Control System is executed. In this proceeding, the reasons that lead to start a complex instrument development instead of using a Commercial On the Shelf (COTS) solution will be discussed. The results of the produced units will be analyzed in terms of accuracy and processing capabilities. Finally, different Em# applications in particle accelerators will be described, further widening the functionality of the current state-of-the-art instrumentation.

	Funding: This work was in part supported by the Horizon 2020 program of the European Union (iNEXT grant, project No. 653706) Originally conceived at ESRF and first deployed in 2005 MXCuBE, Macromolecular Xtallography Customized Beamline Environment, has with its successor MXCuBE2, become a successful international collaboration. The aim of the collaboration is to develop a beamline control application for macromolecular crystallography (MX) that are independent of underlying instrument control software and thus deployable at the MX beamlines of any synchrotron source. The continued evolution of the functionality offered at MX beamlines is to a large extent facilitated by active software development. New demands and advances in technology have led to the development of a new version of MXCuBE, MXCuBE3, The design of which was inspired by the results of a technical pre-study and user survey. MXCuBE3 takes advantage of the recent development in web technologies such as React and Redux to create an intuitive and user friendly application. The access to the application from any web browser further simplifies the operation and natively facilitates the execution of remote experiments.

TUMPL08	MAX IV BioMAX Beamline Control System: From Commissioning Into User Operation	318
	M. Eguiraun, R. Appio, V.H. Hardion, J. Lidón-Simon, A. Milan-Otero, U. Müller, J. Nan, D.P. Spruce, T. Ursby MAX IV Laboratory, Lund University, Lund, Sweden
	The BioMAX beamline at MAX IV is devoted to macromolecular crystallography and will achieve a high level of experimental automation when its full potential is reached due to the usage of high end instrumentation and comprehensive software environment. The control system is based on Tango and Sardana for managing the main elements of the beamline. Data acquisition and experiment control is done through MXCuBE v3, which interfaces with the control layer. Currently, the most critical elements such as the detector and diffractometer are already integrated into the control system, whereas the integration of the sample changer has already started. BioMAX has received its first users, who successfully collected diffraction data and provided feedback on the general performance of the control system and its usability. The present work describes the main features of the control system and its operation, as well as the next instrument integration plans

THPHA070	Multiplexer for the Em# Electrometer	1548
	P. Sjöblom, A. Milan-Otero, A.G. Persson MAX IV Laboratory, Lund University, Lund, Sweden
	Small currents need to be measured from a number of devices at a synchrotron and its beamlines. To meet this demand, MAX IV have joined a collaboration with ALBA to develop an electrometer that will ensure low current measurement capabilities and seamless integration into our Tango control system. The electrometers 4 independent channels can measure accurately in the fA range. Many devices produce larger currents and only need low sample rate. To make the electrometer more flexible, MAX IV have therefore developed a multiplexer with 8 independent channels. The multiplexer is both powered and controlled by the electrometer through its multipurpose IO interface. At most, an electrometer can control 4 multiplexers simultaneously giving a system with 32 channels, but the number of multiplexers can be chosen freely. The offset current introduced by the multiplexer is 45 pA and the noise is 3 pA. The offset is eliminated by settings in the electrometer. Current sweeps shows that currents steps as small as 10 pA can easily be measured and that switching time between channels before a steady signal is achieved is limited by the filter needed by the electrometer and not the multiplexer.

THPHA170	Usage and Development of Web Services at MAX IV	1826

	The web continues to grow as an application platform, with accessibility and platform independence as major benefits. It also makes it possible to tie services together in new ways through simple APIs. At MAX IV we are using web services for various purposes related to the control system, for example, monitoring servers and services, accessing alarm history, viewing control system status, managing system and users logs and running recurring jobs. Furthermore, all user management is also accessed via web applications, and even data analysis and experiment control can now be performed via web based interfaces. We make an effort to use existing tools whenever possible (e.g. Kibana, Prometheus), and otherwise develop systems in-house, based on current well established libraries and standards, such as JavaScript, Python, Apache, etc. This paper presents an overview of our activities in the field and describes different architectural decisions taken.
