MOPRC009	Simulating Apertures in the Uniform Equivalent Beam Model	simulation, quadrupole, optics, space-charge	87
	G.H. Gillespie G.H. Gillespie Associates, Inc., Del Mar, California, USA
	The uniform equivalent beam model is useful for simulating particle beam envelopes. Beam root-mean-square (rms) sizes, divergences, and emittances of an equivalent uniform beam approximate well the rms properties of more realistic beam distributions, even in the presence of space charge. Envelope simulation codes for high current beams using the model, such as TRACE 3-D, are central to particle optics design. However, the modeling of apertures has required multi-particle simulation codes. Multi-particle codes do not typically have the fitting and optimization capabilities common to envelope codes, so the evaluation of aperture effects is often a secondary study that may result in further design iteration. To incorporate aperture effects into the optics design at the start, a method has been developed for simulating apertures in the context of a uniform equivalent beam. The method is described and its TRACE 3-D implementation is outlined. Comparisons with multi-particle simulations are used to validate the method and examine regions of applicability.

MOPRC011	FRIB Lattice-Model Service for Commissioning and Operation	simulation, lattice, operation, database	90
	D.G. Maxwell, Z.Q. He, G. Shen FRIB, East Lansing, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DESC0000661, the State of Michigan and Michigan State University. Accelerator beam simulation is crucial for the successful commissioning and operation of the FRIB linear accelerator. A primary requirement of the FRIB linear accelerator is to support a broad range of particle species and change states. Beam simulations must be performed for these various accelerator configurations and it is important the results be managed to ensure consistency and reproducibility. The FRIB Lattice-Model Service has been developed to manage simulation data using a convenient web-based interface, as well as, a RESTful API to allow integration with other services. This service provides a central location to store and organize simulation data. Additional features include search, comparison and visualization. The system architecture, data model and key features are discussed.

MOPLR012	Compact Beam Position Monitor for Electron and Proton Machines	proton, electron, linac, synchrotron	161
	M. Žnidarčič, M. Cargnelutti I-Tech, Solkan, Slovenia
	Monitoring and subsequent optimization of the linacs, transfer lines, energy recovery linacs and synchrotrons, requires specific instrumentation optimized for beam position and charge measurements. Libera Spark is the newly developed instrument intended for position and charge monitoring in electron and proton machines. The motivation, processing principles and first results at laboratories are presented.

	The Drift Tube Linac (DTL) of the European Spallation Source (ESS) is designed to operate at 352.2 MHz with a duty cycle of 4% (3 ms pulse length, 14 Hz repetition period) and will accelerate a proton beam of 62.5 mA pulse peak current from 3.62 to 90 MeV. In this paper the DTL beam dynamics comparison between the s-code TraceWin and the t-code Parmela is presented. Full field map of the permanent magnet quadrupoles (with COMSOL) and RF fields of each of the 5 tanks (with MDTFish) were used for the two programs.

THPRC032	Towards User Defined Web Applications in Accelerator Labs	database, interface, EPICS, GUI	843
	D. Liu FRIB, East Lansing, USA
	Most Web application users in accelerator labs understand the basics of data types and data structures. They have in-depth knowledge about accelerator physics and other engineering domains. Some even develop software applications by themselves. In the approach of user-defined web applications, a user defines her/his own web application, test and use it first before sharing it to other users. It saves the communication efforts between developers and users, reduces the time from application design to production. Most importantly, users become the owner of the application and naturally the owner of the data that the application collects and produces. This will largely improve an application's quality and user experience. At FRIB, we have been practicing this approach. One of our applications, the traveler, has been developed and operated for about three years, and used by users from various departments including cryomodule, electrical engineering, controls, and business development. The traveler application allows users to design their data collection interface in a what-you-see-is-what-you-get way, and to release it by sharing with other users and groups in the lab. We are now designing and developing a generic data store that will enable users to define their own data structure, to track structure and instance value changes, and to control the access to the data. This material is based upon work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661, the State of Michigan and Michigan State University.
