TI - Comparison between Measured and Computed Temperatures of the Internal High Energy Beam Dump in the CERN SPS J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - The SPS high energy internal dump (TIDVG) is designed to receive beam dumps from 10².2 to 450 GeV. The absorbing core is composed of 2.5m graphite, followed by 1m of aluminium, then 0.5m of copper and finally 0.3m of tungsten, all of which is surrounded by a water cooled copper jacket. An inspection during Long Shutdown 1 revealed significant beam induced damage to the Al section of the dump block. Temperature sensors were installed to monitor the new dump replacing the damaged one. This paper summarises the correlation between the temperature measured as a function of the energy deposited and the same temperatures computed in a numerical model combining FLUKA and ANSYS simulations. The goal of this study is the assessment of the thermal contact quality between the beam absorbing blocks and the copper jacket, by analysing the cooling times observed from the measurements and from the thermo-mechanical simulations. This paper presents an improved method to estimate the efficiency and long term reliability of the cooling of this type of design, with the view of optimising the performance of future dump versions.
