LabVIEW and NI Hardware Automate Gas Leak Testing in the CERN Supercollider’s ATLAS Experiment

Figure 1: The ATLAS (A Toroidal LHC Apparatus) experiment is one of the four major collaborative projects at the CERN LHC.

"LabVIEW helped us observe the behavior of the PID controller and the time evolution of the parameters."


The Challenge:
Performing automatic gas leak tests at the atmospheric pressure range on 128 gas supply lines and 1,200 resistive plate chamber (RPC) detectors installed in the CERN Large Hadron Collider (LHC) ATLAS experiment.

The Solution:
Implementing a PID controller, which is based on LabVIEW and NI data acquisition hardware, to stabilize gas flow and testing pressure at low levels, making it possible to automatically, directly, and precisely measure gas loss.
