Assessment of Static Heat Loads in the LHC Arc, from the Commissioning of Sector 7-8

This note presents first estimates of the static heat loads in the LHC arc cryostats, evaluated experimentally during the commissioning of sector 7-8 in April 2007. Heat loads to the thermal shielding are estimated from the non-isothermal cooling of the supercritical helium in line E, while heat loa...

description This note presents first estimates of the static heat loads in the LHC arc cryostats, evaluated experimentally during the commissioning of sector 7-8 in April 2007. Heat loads to the thermal shielding are estimated from the non-isothermal cooling of the supercritical helium in line E, while heat loads to the 1.9K level of the cold masses are estimated from the internal energy balance during a natural warm-up of the sector in the absence of active cooling. A comparison of the measured heat loads with the budgeted heat loads is then presented and discussed.
