Description
Abstract – In this talk is presented the work carried out at LASA
Laboratory in the years 1995 - 1999, related to the design of a new
type of quadrupoles for the LHC low-beta insertion based on Nb3Sn
technology.
The work deals of the power generated into the insertion quads from
the reaction products of the 7TeV p-p collision in the high
luminosity interaction point of LHC.
The simulation starts from the DTUJET event generator; the reaction
products are then tracked along the magnetic structure of the
insertions; the interaction with the accelerator beam pipe and the
magnets is treated by the FLUKA code.
The keypoint of this work is the thermal analysis of the magnet under
such energy deposition conditions. The simple evaluation of the
energy deposed in the magnet cannot give any indication of the
behaviour of the magnet in this operating conditions, what is really
important is the thermal “response” of the magnet.
A 2 dimension finite elements thermal analysis (ANSYS) evaluate the
temperature increase in the coils and the stability margin,
considering the energy deposed inside the magnets
