TUP029 | A Hybrid Approach to Upgrade Hardware for the Proton Storage Ring Fast Kicker | controls, kicker, proton, storage-ring | 250 | ||

Funding: Work supported by the U.S. Department of Energy, contract no. 89233218CNA000001. LA-UR-23-25123 The Los Alamos Neutron Science Center (LANSCE) Proton Storage Ring (PSR) needs precise timing to ensure successful extraction of the bunched protons. The current control system¿s hardware is obsolete and unmaintainable. The task was to replace the 1980¿s era CAMAC control and timing system for the PSR extraction kickers. This included a system which halts charging of the kickers after a duration without firing to prevent equipment damage. A hybrid approach was taken to integrate a Berkeley Nucleonics Corporation (BNC) pulse generator that was controlled by a soft input/output controller (IOC) and National Instrument compact Reconfigurable Input/Output (cRIO) IOC. This allowed for flexibility and modularity of the software and hardware development. This approach built the framework to streamline robust deployment of hybrid systems and develop a solution for upgrades of other LANSCE kickers. |

TUP045 | Real Time Momentum Spread Measurement of the CERN Antiproton Decelerator Beam | operation, real-time, diagnostics, software | 293 | ||
|
|||||
Constant optimisation and diagnostics of the cooling processes in the CERN antiproton decelerator (AD) relies on a de-bunched beam momentum spread real time measurement. This article will describe the renovation of the acquisition chain of the longitudinal Schottky diagnostics in the AD, using standard CERN hardware and software to maximize reliability, ease maintenance, and meet the requirements for standard operational tools. The whole chain, from the pick-up to the operation software applications will be described with emphasis on the implementation of the data processing running on the front-end computer. Limitations will also be discussed and outlook for further development given. | |||||

WE2C03 | Beam Instrumentation Hardware Architecture for Upgrades at the BNL Collider-Accelerator Complex and the Future Electron Ion Collider | instrumentation, electron, collider, power-supply | 308 | ||
|
|||||
Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. Many beam instrumentation systems at Brookhaven National Laboratory¿s Collider-Accelerator complex are over 20 years old and in need of upgrading due to obsolete components, old technology and the desire to provide improved performance and enhanced capabilities. In addition, many new beam instrumentation systems will be developed for the future Electron Ion Collider (EIC) that will be housed in the existing Relativistic Heavy Ion Collider (RHIC) tunnel. A new BNL designed custom hardware architecture is planned for both upgrades in the existing facility and new systems for the EIC. A general-purpose carrier board based on the Xilinx Zynq Ultrascale+ System-on-Chip (SoC) will interface with a family of application specific daughter cards to satisfy the requirements for each system. This paper will present the general architecture that is planned, as well as details for some of the application specific daughter cards that will be developed. |

WEP028 | LANSCE High Density Emittance Instrumentation System | emittance, instrumentation, controls, data-acquisition | 413 | ||
|
|||||
Funding: Work supported by the U.S. Department of Energy, contract no. 89233218CNA000001. LA-UR-23-25123 The Los Alamos Neutron Science Center (LANSCE) is currently upgrading the existing emittance stations with a high-density instrumentation system for emittance measurements in the low energy beam transport region. Emittance measurements were obtained using obsolete legacy equipment. For motion control a switching station with a mechanical mux to switch actuators was used. This caused a single point of failure for all emittance stations and is becoming increasingly unreliable. For data acquisition, two sets of signal conditioning and digitizers were employed and had to be shared between 7 emittance stations. Physical cable swapping was necessary when taking measurements from station to station. A system was developed using dedicated Quad Actuator Controller (QAC) chassis, capable of driving four (4) actuators, and dedicated data acquisition (DAQ) chassis capable of signal conditioning and digitizing up to 80 channels simultaneously. Details of the system development are presented. |

WEP029 | LANSCE QAC/DAQ Wire Scanner Instrumentation Upgrade | controls, instrumentation, data-acquisition, impedance | 415 | ||
|
|||||
Funding: Work supported by the U.S. Department of Energy, contract no. 89233218CNA000001. LA-UR-23-25124 High density instrumentation has been developed to upgrade wire scanner beam diagnostic capability in all areas downstream of the Coupled Cavity LINAC (CCL). Transverse beam profile measurements were originally obtained using legacy electronics known as Computer Automated Measurement and Control (CAMAC) crates. CAMAC has become obsolete, and a new wire scanner diagnostic system was developed as a replacement. With high wire scanner device density located in each area, instrumentation was developed to meet that need along with the ability to interface with legacy open-loop controlled actuators and be forward compatible with upgraded closed-loop systems. A high-density system was developed using a Quad Actuator Controller (QAC) and Data Acquisition (DAQ) chassis that pair together using a sequencer when taking measurements. Software improvements were also made, allowing for full waveform functionality that was previously unavailable. Deployment of 52 wire scanner locations in 2022 increased device availability and functionality across the facility. Hardware and software design details along with results from accelerator beam measurements are presented. |

WEP043 | Upgrade of the ELBE Timing System | timing, operation, software, controls | 446 | ||
|
|||||
The CW electron accelerator ELBE is in operation for more than two decades. The timing system has been patched several times in order to meet changing requirements. In 2019 the development of a new timing system based on Micro Research Finland Hardware has been started which is designed to unify the heterogeneous structure and to replace obsolete components. In spring 2023 the development of the software has been accomplished, which included the mapping of operation mode and different complex beam patterns onto the capabilities of the commercial platform. The system generates complex beam patterns from single pulse, to macro pulse and 26 MHz cw operation including special triggers for diagnostics and machine subsystems. The contribution will describe the path from requirements to development and commissioning of the new timing system at ELBE. | |||||
