SAMbuCa: Sensors Acquisition and Motion Control Framework at CERN
/ Masi, Alessandro (CERN) ; Andreassen, Odd (CERN) ; Arruat, Michel (CERN) ; Danzeca, Salvatore (CERN) ; Di Castro, Mario (CERN) ; Donzé, Mathieu (CERN) ; Fargier, Sylvain (CERN) ; Ferraro, Rudy (CERN) ; Gulin, Marco (CERN) ; Kozsar, Ioan (CERN) et al.
Motion control systems at CERN often have challenging requirements, such as high precision in extremely radioactive environments with millisecond synchronization. These demanding specifications are particularly relevant for Beam Intercepting Devices (BIDs) such as the collimators of the Large Hadron Collider (LHC). [...]

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.

Enhancing Measurement Quality in HL-LHC Magnets Testing Using Software Techniques on Digital Multimeter Cards-Based System
/ Reymond, Hubert (CERN) ; Andreassen, Odd (CERN) ; Charrondiere, Maryline (CERN) ; Charrondière, Cedric (CERN) ; Jankowski, Patryk (CERN)
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. [...]

LINAC4 Laser Profile and Emittance Meter Commissioning
/ Goldblatt, Aurélie (CERN) ; Andreassen, Odd (CERN) ; Boorman, Gary (JAI, UK) ; Bosco, Alessio (JAI, UK) ; Gibson, Stephen (JAI, UK) ; Hofmann, Thomas (Unlisted, CH) ; Roncarolo, Federico (CERN) ; Tagg, Joseph (CERN)
The CERN LINAC4 is now equipped with two laser profile and emittance meters, a basically non destructive measurement of the transverse beam profile, not limited by the beam power density. The light of a pulsed laser is trans- ported through optical fibers and focused into the 160 MeV/c $H^{-}$ beam. [...]

In this contribution we provide a summary of the LHC hardware commissioning campaign following the second CERN Long Shutdown (LS2), initially targeting the nominal LHC energy of 7 TeV. A summary of the test procedures and tools used for testing the LHC superconducting circuits is given, together with statistics on the successful test execution. [...]

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. [...]
