1. Dogleg Thermal Tests : Configuration 7 6 AiN plate side Jan 4 2002. SM+LB 8 Dogleg side Heater (0.4W) 2 1 3 4 5 67 8 flow 2 Temperature sensors located at positions 1-8.

2. Cooling Block Alumina dummy module Clip Coolant pipe Ceramic heater

3. Cooling block, Dogleg, and dummy module assembly

4. Orientation of dT1, dT2 and dT3 on the Dogleg dT1 dT2 (Cooling block) dT3 Upper face Lower face

5. Test setup, left and right: resevoir (-14° nominally), test chamber (-7° nominally)

6. 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.

7. dTs vs environment temperature
