The high energy physics experiments developed at CERN for the High Luminosity Large Hadron Collider (HL-LHC) are based on optical links that provide the clock distribution and control towards the front-end electronics located in the experiments, and data transmission back from these electronics circuits to remote data acquisition systems. The corresponding data is encoded and decoded by custom integrated circuits able to stand the high level of radiation in this specific environment. In particular for the Trackers at the HL-LHC, a low-power gigabit transceiver was developed (LPGBT).
This prototype presents a new phase in the development and implementation of a remotely-controlled one-way flow control valve, which is used for the remote control of actuator velocity in pneumatic control systems. In this way, the optimum, not the maximum possible actuator velocity at all times is enabled. This directly effects the reliability of the system as it extends the working life of component.
