Thermohydraulics of quenches and helium recovery in the LHC prototype magnet strings.
Author(s) : CHOROWSKI M., LEBRUN P., SERIO L., WEELDEREN R. van
Summary
In preparation for the Large Hadron Collider (LHC) project, a 42.5 m-long prototype superconducting magnet string, representing a half-cell of the machine lattice, has been built and operated. A series of tests was performed to assess the thermohydraulics of resistive transitions (quenches) of the superconducting magnets. These measurements provide the necessary foundation for describing the observed evolution of the helium in the cold mass and formulating a mathematical model based on energy conservation. The evolution of helium after a quench simulated with the model reproduces the observations. The authors then extend the simulations to a full LHC cell, and finally analyse the recovery of helium discharged from the cold mass.
