It will provide users and beamline scientists with tools to manage the logistics and scientific metadata for their experiments. For scientific samples it will allow users to ship them to Diamond, track where they are within the experiment hall, and store data about them. Universal LIMS...
This paper introduces an automated fault analysis framework for the Advanced Light Source (ALS) that processes real-time event logs from its EPICS control system. By treating log entries as natural language, we transform them into contextual vector representations using semantic embedding techniques. A sequence-aware neural network, trained on normal operational data, assigns a real-time...
The ISIS Neutron and Muon Facility accelerators are migrating to an EPICS control system. The tools developed to run two control systems in parallel and to automate the migration of hardware and user interfaces to EPICS have been previously presented. We now detail our emerging EPICS setup. Hardware interfaces are implemented as a mixture of conventional EPICS IOCs, in-house developed...
At the experiments of the CERN Large Hadron Collider (LHC), 31 gas systems are used to deliver a precise gas mixture to the corresponding detectors with high reliability and availability*. The Distribution Modules of these gas systems control and monitor gas flow and pressure across thousands of channels. The Embedded Local Monitor Board (ELMB), an I/O board using the CANopen communication...
LANSCE delivers macropulses of beam, hundreds of microseconds in duration and at a nominal repetition rate of 120 Hz, to five experiment areas. These macropulses are distributed to four H⁻ areas and one H⁺ area. Each of the H⁻ experiment areas require a unique beam time structure within the macropulse. This time structure is imposed on the beam by a traveling wave chopper located in the H- Low...
This paper presents the current approach to upgrade the readout instrumentation for the Proton Storage Ring (PSR) Extraction Line Beam Position Monitor System (ExBPMs) that are located between PSR and Lujan center Target at the Los Alamos Neutron Science center (LANSCE) accelerator. National Instrument’s PXIe platform with high-speed digitizers have been chosen as the hardware which will...
The Advanced Light Source (ALS) at Lawrence Berkeley National Laboratory, a third-generation synchrotron light source, has been in continuous operation since 1992. The ALS beamline equipment protection system is being upgraded by replacing legacy end-of-life Modicon PLCs with Allen-Bradley PLCs. This paper presents the software architecture of the upgraded system, highlighting the...
The LCLS-II High Energy (LCLS-II HE) upgrade at SLAC National Accelerator Laboratory involves the delivery and long-term storage of superconducting cryomodules, manufactured at partner laboratories and shipped to SLAC. To maintain their performance, these cryomodules must preserve ultra-high vacuum (UHV) conditions prior to installation. Upon arrival, each unit undergoes a comprehensive...
