Cryogenics of a superconducting LINAC : SPIRAL2 from commissioning to operation
Adnan Ghribi, Muhammad Aburas, Pierre-Emmanuel Bernaudin +11
The SPIRAL2 superconducting linear accelerator (LINAC), which has been operational since 2019, employs superconducting, independently phased RF resonators to deliver a wide range o…
Advanced cryogenic process control and monitoring for the SPIRAL2 superconducting LINAC
Adnan Ghribi, Muhammad Aburas, Pierre-Emmanuel Bernaudin +8
SPIRAL2 is a superconducting accelerator for protons, deuterons and heavy ions delivering a maximum beam power of 200 kW at 40 MeV (for deuteron beams). 26 superconducting quarter…
On the use of Anderson acceleration in hierarchical control
Xuan-Huy Pham, Mazen Alamir, François Bonne +1
This paper investigates the use of fixed-point Anderson acceleration method (AA) to a recently proposed hierarchical control framework. Due to its model-free property, the AA-based…
Approximate explicit model predictive control via piecewise nonlinear system identification
Van-Vuong Trinh, Mazen Alamir, Patrick Bonnay
This article presents an identification methodology to capture general relationships, with application to piecewise nonlinear approximations of model predictive control for constra…
