The Enhanced Liquid Interface Spectroscopy and Analysis (ELISA) beamline is a new instrument at BESSY II focusing on a novel, integrated approach for the high-fidelity preparation and investigation of liquid interfaces using soft x-ray radiation and infrared radiation light generated simultaneously from the BESSY II light source. As ELISA is part of the BESSY II+ upgrade scheme* it will be...
Controls engineers in scientific facilities manage numerous projects, support multiple Customer Units (CUs), and balance operational demands with new initiatives. This often leads to growing backlogs and staff stress. Meanwhile, managers struggle to allocate resources across CUs, frequently prioritizing short-term goals at the expense of long-term strategy. At ALBA, such pressures prompted a...
The TSU's (Trigger Synchronization Unit ) purpose is to synchronize beam dump requests with the Beam Abort Gap (BAG) upon request from clients, primarily the Beam Interlock System (BIS). Synchronization is crucial to prevent damaging absorbers/collimators and cryo ring magnets.
The TSU system, per beam, comprises two interconnected, redundant chassis for synchronization. It internally...
Full utility of Diamond IIโs increased brilliance and coherence will require next generation scanning, capable of operating at high speed in the nano-scale regime. At this level, motion systems can become highly non-linear and under actuated creating challenges beyond the capabilities of traditional control methodologies. The new architecture, and more specifically, the high performance FPGA...
The Linear Coherent Light Source (LCLS) has developed a pulse-by-pulse data acquisition system, Beam-Synchronized Acquisition (BSA), to support the transition from normal-conducting (NC) to superconducting (SC) accelerator operation. BSA evolved from a 360โฏHz software-based system to a 1โฏMHz firmware-based architecture tightly integrated with the LCLS timing system and beam rate.
Alongside...
The Matter in Extreme Conditions Upgrade (MEC-U) is a Department of Energy (DOE) Fusion Energy Sciences (FES) funded project slated for construction at the SLAC National Accelerator Laboratory later this decade. The facility will deliver the Linac Coherent Light Source (LCLS) X-ray Free Electron Laser (XFEL) beam to an experiment target chamber, coordinated with two high-power laser systems: a...
The control of fast pulsed magnet systems at CERN requires often a common set of fast digital electronics sub-systems to perform tight timing control and fast protection of high-voltage pulse generators. Although the generators architecture is mainly modular, these control systems were until now most of the time centralized: several generators per equipment, but one global and...
Single-bunch beam position monitors (BPM) are used to track the trajectory and measure turn-by-turn positions of a single bunch of electrons while multiple bunches are present in the storage ring. In the Advanced Photon Source Upgrade (APS-U), 20 single-bunch BPMs have been installed in the first three sections right after the injection point. For each BPMs, an RF switch is used to select the...
This presentation covers the history of Fermilab's Tevatron Clock (TCLK) timing system and how it has served to regulate the facility over the past 40 years. The presentation provides an overview of beamlines at Fermilab, the challenges of timing in a Rapid Cycling Synchrotron, and the transfer scenarios utilized to generate megawatt-class beam at America's "premier" high energy physics...
When the SNS site was built around 20 years ago, the Conventional Facilities (CF) control systems were designed using 2 communication protocols to allow programmable logic controllers (PLCs) to interface with motors, variable frequency drives (VFDs), and distributed inputs and outputs (I/O). The protocol chosen to control motors and VFDs is DeviceNet, a CANbus-based protocol developed by...
