L. Rossi et al., THERMAL-BEHAVIOR AND CRYOGENIC PERFORMANCE OF THE FIRST CERN INFN PROTOTYPE DIPOLE CRYOMAGNET FOR THE CERN LHC PROJECT/, Cryogenics, 34, 1994, pp. 697-700
The first 10 m long LHC prototype dipole magnet produced in industry h
as been mounted on the measurement test bench and operated at 1.8 K in
a static bath of pressurized helium II. During tests its thermo-mecha
nical and cryogenic behaviour has been measured. The cool down under d
ifferent conditions, the resulting temperature gradients and the therm
o-hydraulic consequences of resistive transitions have been investigat
ed.
