	Funding: ANR (DYNACO project), FEDER, CEMPI LABEX. Single-shot recording of pulses is possible with high repetition rates (more than 80 MHz), as was demonstrated in the framework of a PhLAM-SOLEIL collaboration * *. This can be achieved by a relatively simple upgrade of existing setups based on spectral encoding. The strategy consists to encode the sub-picosecond information into the time domain, but at a slower scale (nanoseconds), using dispersion in a long optical fiber. Then the information is recorded by a photodiode connected to an oscilloscope. In this poster, we present guidelines for the practical realization of the electro-optical setup, as well as a performance analysis. In particular, we analyze the temporal resolution and compare it to the classical electro-optical sampling setup. E. Roussel et al., Proceedings of IPAC2014, THOBA01. ** E.

WEPMA014	Development of New Microcontroller Based Power Supply Control Units at ELSA	controls, interface, timing, power-supply	2777
	D. Proft, W. Hillert, T. Perlitius ELSA, Bonn, Germany
	At the electron stretcher facility ELSA electrons are accelerated with a high ramping speed of 6 GeV/s. This leads to strong requirements on the main magnets power supplies. In particular, any synchronization errors directly result in beam tune shifts and, at worst, beam loss. The existing thirty years old control units are now being replaced by new in-house developed versatile microcontroller based ones. These allow the application of arbitrary ramp patterns and actual value acquisition in realtime. With an ethernet interface the ramp patterns can be uploaded directly to the power supplies. The flexible design also allows usage of the module to control other power supplies, e.g. those of the orbit correction magnets. This presentation will give details on the developed hardware design and the performance of the modules compared to the existing ones.

	The architecture of power SCADA system of TPS and its monitored real time data are described in this report. The on-line monitored and measured items include voltage/current, real power/reactive power, power factor, harmonic distortion, etc. These data are presented in trend charts. The electric energy, the power quality and the harmonic distortion obtained with the SCADA system are used to study the status of the power system, and also provide information for the future improvement.

WEPTY057	Adaptable Machine Protection Architecture for CW, High Intensity Accelerators	database, operation, framework, network	3402
	S. Assadi Texas A&M University, College Station, Texas, USA
	Funding: Work is partially supported by grants from the State of Texas (ASE) & the Michelle foundation An adaptable architecture of a machine protection system (MPS) suitable for continuous wave (cw), high intensity accelerators like those proposed for Accelerator Driven Systems (ADS) for subcritical reactor strategies and heavy ion accelerators for the production of rare isotopes is presented. A system of databases, networks and nodes that can systematically and flexibly be reconfigured to rebalance the required metadata is used. Additional features include reconfigurable machine setup templates that can rigorously be tested with mirror redundant online backups, the utilization of external reconfigurable geometric algorithms for the data channels and the network distribution, and the inclusion of initial system requirements as well as envisioned upgrades.
