	For Indus-2, a 2.5 GeV Synchrotron Radiation Source, operational at Indore, India, the need was felt for software for easily managing various related activities for avoiding communication gaps among the crew members and clearly bringing out the important communications for machine operation. Typical requirements were to have the facility to enter and display daily, weekly and longer operational calendars, to convey system specific and machine operation related standing instructions, to log and track the faults occurring during the operations and follow up actions on the faults logged etc. Overall, the need was for a system to easily manage the number of jobs related to planning the day to day operations of a national facility. The paper describes such a web based system developed and in use regular use and found extremely useful.

	To study the synchrotron terahertz emission superconducting (YBCO) film detectors are used with the intrinsic response time in the order of a few picoseconds. For fast, continuous sampling of the individual THz ultra-short pulses a novel digitizer system has been developed. The system consists of detector, wideband low-noise amplifier, fast pulse digitizer board, back-end readout board. High-end graphic processing units (GPUs) perform real-time data analysis. Four samples with 12 bit are recorded in parallel for each fast pulse with programmable sampling times in the range of 3 to 100 ps. A new bus master DMA engine connected to PCI express endpoint has been developed to ensure a continuous high data throughput of up to 4 GByte/s. This heterogeneous real-time system architecture based on FPGA and GPU has successful been used for on-line pulse reconstruction and evaluations and calculates the peak amplitude of each pulse and the time between consecutive bunches with a picosecond time resolution at ANKA. A Fast Fourier Transform (FFT) is performed on-line for the frequency analysis of the CSR undulations.

	Funding: Supported by the Knowledge Innovation Program of Chinese Academy of Sciences To improve the accelerator reliability and stability, a beam data logging system was built at SSRF, which is base on NOSQL database Couchbase. The Couchbase is an open source software, and can be used both as a document database or pure key-value database. The logging system stores beam parameters under predefined conditions. It is mainly used for the fault diagnosis, beam parameters tracking or automatic report generation. The details of the data logging system will be reported in this paper.

FPO024	First Idea on Bunch to Bucket Transfer for FAIR	timing, target, network, flattop	210

	The FAIR facility makes use of the General Machine Timing (GMT) system and the Bunch phase Timing System (BuTiS) to realize the synchronization of two machines. In order to realize the bunch to bucket transfer, firstly, the source machine slightly detunes its RF frequency at its RF flattop. Secondly, the source and target machines exchange packets over the timing network shortly before the transfer and make use of the RF frequency-beat method to realize the synchronization between both machines with accuracy better than 1o. The data of the packet includes RF frequency, timestamp of the zero-crossing point of the RF signal, harmonic number and bunch/bucket position. Finally, both machines have all information of each other and can calculate the coarse window and create announce signals for triggering kickers.

FPO031	Power Supplies Transient Recorders for Post-Mortem Analysis of BPM Orbit Dumps at Petra-III	controls, emittance, power-supply, operation	225
	G.K. Sahoo, P.K. Bartkiewicz, A. Kling, B. Pawlowski DESY, Hamburg, Germany
	PETRA-III is a 3rd generation synchrotron light source dedicated to users at 14 beam lines with 30 instruments. The storage ring is presently modified to add 12 beam lines. PETRA III was operated with several filling modes such as 40, 60, 480 and 960 bunches with a total current of 100mA at electron beam energy of 6 GeV. The horizontal beam emittance is 1 nmrad while a coupling of 1% amounts to a vertical emittance of 10 pmrad. During a user run Machine Protection System (MPS) may trigger an unscheduled beam dump if transients in the current of magnet power supplies are detected which are above permissible limits. The trigger of MPS stops the ring buffers of the 226 BPM electronics where the last 16384 turns just before the dump are stored. These data and transient recorder data of Magnet Power Supply Controllers are available for a post-mortem analysis. Here we discuss in detail the functionality of a Java GUI used to investigate the transient behavior of the differences between set and readout values of different power supplies to find out the responsible power supply that might have led to emittance growth, fluctuations in orbits or beam dumps seen in a post-mortem analysis.

FPO034	Beamline Data Management at the Synchrotron ANKA	data-management, interface, controls, database	231
	A. Vondrous, T. Jejkal, W. Mexner, D. Ressmann, R. Stotzka KIT, Eggenstein-Leopoldshafen, Germany
	We present an architecture consisting of measurement devices, beamline data management and data repository to enable data management at the synchrotron facility ANKA. The operators perform some data management tasks manually and individually for each measurement method. In order to provide the functionality of a data repository it is necessary to collect the data, aggregate metadata and to perform the ingests into the data repository. The data management layer between the measurement devices and the data repository is referred to beamline data management (BLDM), which performs data collection, metadata aggregation and data ingest. Shared libraries contain functionality like migration, ingest or metadata aggregation and form the basis of the BLDM. The workflows and the current state of execution are persisted to enable monitoring and error handling. After data ingest into the data repository, implemented with the KIT Data Manager, archiving, content preservation or bit preservation services are provided for the ingested data. BLDM can connect the existing infrastructure with the data repository without major changes of routine processes to build a data repository for a synchrotron.

FCO202	OpenGL-Based Data Analysis in Virtualized Self-Service Environments	software, network, GPU, hardware	237
	V. Mauch, M. Bonn, S.A. Chilingaryan, A. Kopmann, W. Mexner, D. Ressmann KIT, Karlsruhe, Germany
	Funding: Federal Ministry of Education and Research, Germany Modern data analysis applications for 2D/3D data samples apply complex visual output features which are often based on OpenGL, a multi-platform API for rendering vector graphics. They demand special computing workstations with a corresponding CPU/GPU power, enough main memory and fast network interconnects for a performant remote data access. For this reason, users depend heavily on available free workstations, both temporally and locally. The provision of virtual machines (VMs) accessible via a remote connection could avoid this inflexibility. However, the automatic deployment, operation and remote access of OpenGL-capable VMs with professional visualization applications is a non-trivial task. In this paper, we discuss a concept for a flexible analysis infrastructure that will be part in the project ASTOR, which is the abbreviation for “Arthropod Structure revealed by ultra-fast Tomography and Online Reconstruction”. We present an Analysis-as-a-Service (AaaS) approach based on the on-demand allocation of VMs with dedicated GPU cores and a corresponding analysis environment to provide a cloud-like analysis service for scientific users.
