Beam dynamics requirements for HL–LHC electrical circuits
A certain number of LHC magnets and relative electrical circuits will be replaced for the HL-LHC upgrade. The performance of the new circuits will need to be compatible with the current installation, and to provide the necessary improvements to meet the tight requirements of the new operational scenario.

The proof of principle of a real-time data acquisition system to be integrated into a digital control loop for controlling the power converters of the Compact LInear Collider is presented. The system is based on an ultra low noise analogue front-end with 1:1 ppm RMS noise (referred to input), and about 1 _s of real-time delay. After the analogue conditioning, a fully-differential analogue-todigital converter is foreseen.

A 15MS/s, 10 ppm repeatable acquisition system to characterize 3 μs rise-time trapezoidal voltage pulses is proposed. The system is based mainly on a low-noise, 5MHz bandwidth analog front-end. In this paper, the requirements, the concept and physical design are illustrated. Simulation results aimed at assessing the circuit performance are presented.

High-quality measurements of pulses are nowadays widely used in fields such as radars, pulsed lasers, electromagnetic pulse generators, and particle accelerators. Whilst literature is mainly focused on fast systems for nanosecond regime with relaxed metrological requirements, in this paper, the high-performance measurement of slower pulses in microsecond regime is faced.
