Test setup, left and right: resevoir (-14° nominally), test chamber (-7° nominally)
Summary of Dogleg dTs and considerations in future tests Convection contributes to these measurements. How will convection affect cooling in the operational barrel environment? Repeating these tests on the sector prototype will provide better understanding of this behaviour. Tests will be repeated using a block with a shunt shield.
