MOPHA015	Reverse Engineering the Amplifier Slab Tool at the National Ignition Facility	database, target, simulation, operation	228
	A. Bhasker, R.D. Clark, J.E. Dorham LLNL, Livermore, California, USA
	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 This paper discusses the challenges and steps required to convert a stand-alone legacy Microsoft Access-based application, in the absence of original requirements, to a web-based application with an Oracle backend and Oracle Application Express/JavaScript/JQuery frontend. The Amplifier Slab Selection (ASL) Tool provides a means to manage and track Amplifier Slabs on National Ignition Facility (NIF) beamlines. ASL generates simulations and parameter visualization charts of seated Amplifier Slabs as well as available replacement candidates to help optics designers make beamline configuration decisions. The migration process, undertaken by the NIF Shot Data Systems (SDS) team at Lawrence Livermore National Laboratory (LLNL), included reverse-engineering functional requirements due to evolving processes and changing NIF usage patterns.

MOPHA047	CERN Secondary Beamlines Software Migration Project	software, controls, database, experiment	312

	The Experimental Areas group of the CERN Engineering department operates a number of beamlines for the fixed target experiments, irradiation facilities and test beams. The software currently used for the simulation of the beamline layout (BEATCH), beam optics (TRANSPORT), particle tracking (TURTLE) and muon halo calculation (HALO) has been developed in FORTRAN in the 1980s and requires an update in order to ensure long-term continuity. The ongoing Software Migration Project transfers the beamline description to a set of newer commonly used software codes, such as MADX, FLUKA, G4Beamline, BDSIM etc. This contribution summarizes the goals and the scope of the project. It discusses the implementation of the beamlines in the new codes, their integration into the CERN layout database and the interfaces to the software codes used by other CERN groups. This includes the CERN secondary beamlines control system CESAR, which is used for the readout of the beam diagnostics and control of the beam via setting of the magnets, collimators, filters etc. The proposed interface is designed to allow a comparison between the measured beam parameters and the ones calculated with beam optics software.

TUCPL02	Processing System Design for Implementing a Linear Quadratic Gaussian (LQG) Controller to Optimize the Real-Time Correction of High Wind-Blown Turbulence	controls, software, real-time, Linux	761
	M. Kim, S.M. Ammons, B. Hackel, L. Poyneer LLNL, Livermore, California, USA
	Funding: This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 with document release number LLNL-PROC-792238. LLNL has developed a low latency, real-time, closed-loop, woofer-tweeter Adaptive Optics Control (AOC) system with a feedback control update rate of greater than 16 kHz. The Low-Latency Adaptive Mirror System (LLAMAS) is based on controller software previously developed for the successful Gemini Planet Imager (GPI) instrument which had an update rate of 1 kHz. By tuning the COTS operating system, tuning and upgrading the processing hardware, and adapting existing software, we have the computing power to implement a Linear-Quadratic-Gaussian (LQG) Controller in real time. The implementation of the LQG leverages hardware optimizations developed for low latency computing and the video game industry, such as fused multiply add accelerators and optimized Fast Fourier Transforms. We used the Intel Math Kernel Library (MKL) to implement the high-order LQG controller with a batch mode execution of 576 6x6 matrix multiplies. We will share our progress, lessons learned and our plans to further optimize performance by tuning high order LQG parameters.

TUCPL07	Optimal Control for Rapid Switching of Beam Energies for the ATR Line at BNL	network, controls, simulation, quadrupole	789
	J.P. Edelen, N.M. Cook RadiaSoft LLC, Boulder, Colorado, USA K.A. Brown, P.S. Dyer BNL, Upton, New York, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Nuclear Physics under Award Number DE-SC0019682. The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory will undergo a beam energy scan over the next several years. To execute this scan, the transfer line between the Alternating Gradient Synchrotron (AGS) and RHIC or the so-called the ATR line, must be re-tuned for each energy. Control of the ATR line has four primary constraints: match the beam trajectory into RHIC, match the transverse focusing, match the dispersion, and minimize losses. Some of these can be handled independently, for example orbit matching. However, offsets in the beam can affect the transverse beam optics, thereby coupling the dynamics. Furthermore, the introduction of vertical optics increases the possibilities for coupling between transverse planes, and the desire to make the line spin transparent further complicates matters. During this talk, we will explore three promising avenues for controlling the ATR line, model predictive control (MPC), on-line optimization methods, and hybrid MPC and optimization methods. We will provide an overview of each method, discuss the tradeoffs between these methods, and summarize our conclusions.

WEDPR03	Synoptic GUIs in NSRC SOLARIS for Beamlines and Accelerators Visualization and Control	controls, TANGO, interlocks, operation	982
	M.K. Falowski, T.R. Noga, N. Olszowska, M. Zając NSRC SOLARIS, Kraków, Poland
	High demand from scientists and operators to create new, clear and intuitive SCADA graphical interfaces for new beamlines and replace or supplement existing beamlines’ and accelerators’ graphical user interfaces is a challenging task. This is not only time consuming but very often requirements from users vary, change quickly and even sometimes they are mutually exclusive. To meet this challenge and provide clear, scalable and ergonomic graphical user interfaces, SOLARIS chose ’Taurus’ and ’svgsynoptic2’ to create synoptic applications which allow to visualize and control beamlines and accelerators with ease. In addition, it was decided to use identical scheme of visualization and control for synoptic applications on all beamlines, so scientists can get used to it, even if they carry out research on different beamlines. This paper presents the overall architecture and functionality of the applications.
