Labview-Based Template for Enhanced Accelerator Systems Control: Software Solutions for the CERN-ISOLDE Facilities / Charrondière, Cedric (CERN) ; Andreassen, Odd (CERN) ; Benoit, Antoine (Unlisted, CH) ; Boorman, Gary (Unlisted, CH) ; Galetti, Elena (CERN) ; Heinke, Reinhard (CERN) ; Le, Line (CERN) ; Marsh, Bruce (CERN) ; Rossel, Ralf (CERN) ; Rothe, Sebastian (CERN) et al.
ISOLDE is part of the experimental infrastructure with-in the CERN accelerator complex that provides radioac-tive ion beams for studies of fundamental nuclear phys-ics, astrophysics, condensed matter physics and medical applications. Complementing the available controls in-frastructure, an easy-to-use set of applications was devel-oped to allow operators to record and display signals from multiple sources, as well as to provide drivers for non-standard, custom-made instruments and specialized off-the-shelf components.

The HL-LHC magnets play a critical role in the High-Luminosity Large Hadron Collider project, which aims to increase the luminosity of the LHC and enable more precise studies of fundamental physics. Ensuring the performance and reliability of these magnets requires high-precision measurements of their electrical properties during testing. [...]

The Micro-Services of Cern’s Critical Current Test Benches / Charrondière, Cedric (CERN) ; Andreassen, Odd (CERN) ; Ballarino, Amalia (CERN) ; Barth, Christian (CERN) ; Boutboul, Thierry (CERN) ; Fleiter, Jerome (CERN) ; Hopkins, Simon (CERN) ; Koziol, Piotr (CERN) ; Reymond, Hubert (CERN)
In order to characterize the critical-current density of low temperature superconductors such as niobium¿titanium (NbTi) and niobium¿tin (Nb₃Sn) or high temperature superconductors such as magnesium-diboride MgB₂ or Rare-earth Barium Copper Oxide REBCO tapes, a wide range of custom instruments and interfaces are used. The critical current of a superconductor depends on temperature, magnetic field, current and strain, requiring high precision measurements in the nano Volt range, well-synchronized instrumentation, and the possibility to quickly adapt and replace instrumentation if needed.

Challenges of Automating the Photocathode Fabrication Process at CERN / Charrondière, Cedric (CERN) ; Chevallay, Eric (CERN) ; Zilliox, Thomas (CERN)
The CERN Photoemission Laboratory was founded in 1989 with the goal of studying laser-driven electron sources, for producing high-brightness electron beams within the framework of the Compact Linear Collider (CLIC) study. To produce these photocathodes, two processes run in parallel. [...]

Lessons Learned Moving from Pharlap to Linux RT / Charrondière, Cedric (CERN) ; Andreassen, Odd (CERN) ; Sierra-Maíllo Martínez, Diego (CERN) ; Tagg, Joseph (CERN) ; Zilliox, Thomas (CERN)
The start of the Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) facility at CERN in 2016 came with the need for a continuous image acquisition system. The international scientific collaboration responsible for this project requested low and high resolution acquisition at a capture rate of 10Hz and 1 Hz respectively. [...]

Synchronizing LabVIEW Development and Deployment Environment / Andreassen, Odd (CERN) ; Charrondière, Cedric (CERN) ; Miskowiec, Martyna (CERN) ; Reymond, Hubert (CERN) ; Rijllart, Adriaan (CERN)
LabVIEW with its graphical approach is suited for engineers used to design and implement systems based on schematics and designs. Being a graphical language, it can be challenging to keep track of drivers, runtime engines, deployments and configurations since most of the tools on the market aimed towards this are implemented for textual languages.

Evaluation of Timing and Synchronization Techniques on NI CompactRIO Platforms / Andreassen, Odd (CERN) ; Charrondière, Cedric (CERN) ; Develle, Kevin (CERN) ; Rossel, Ralf (CERN) ; Zilliox, Thomas (CERN)
For distributed data acquisition and control system, clock synchronization between devices is key. The internal CPU clock of a CompactRIO has an accuracy of 40 ppm at 25 degree Celsius, which can cause up to 3 sec of drift per day. [...]

Wall current monitor using PXI and LabVIEW at CERN / Charrondiere, Cedric (CERN) ; Delrieux, Marc (CERN) ; Limpens, Rik (CERN)
The new data acquisition system for the PS ring wall current monitors installed in the PS is able to perform high frequency measurements of a beam bunch up to a frequency of 2.7 GHz. This is an important improvement, since the oscillating signal within the bandwidth 500-700 MHz, is related to losses of a beam bunch. [...]
