1 Calorimeter Transient Analysis for Steady State with ID Heat Leak and mini-FCal Analysis with 88.5°K Coolant in the Cooling Coil July 25, 2014 Brian Cuerden

2 Steady State Temperatures, ID Heat Leak Only
Fcal 1 Fcal 3

3 Steady State Results Nominal heat load, 20% Ohmic Heating, 10 W ID heat load
Node °K Node °K Node °K Node °K Node °K Node °K Node °K Node °K Node °K Radial Coordinates: Node mm Nodes 4463 and 4023 are at thermocouple locations/ max temp locations Node is in Fcal2 and in Fcal3 near the ID The plotted Temps are steady state, Listed values are at 600,000 seconds

4 Nominal Heat Loads, Full Calorimeter (not half)
FEM loads are taken from FEA results Integrated heat loads are the specified heat loads integrated over the volume specified. ID heat leak is an additional W

5 Temperature Change After Normal Beam Power is Applied

6 Temperature Change after a step application of nominal power
T4023 and T4463 are at temperature sensor locations in Fcal1 T15485 is in FCal2 near the ID T28485 is in Fcal3 near the ID

7 Mini-F-Cal Temperatures at 7
Mini-F-Cal Temperatures at 7.5x nominal power with 24 6x44mm straps to the LN2 tube Max Temp is 92.1°K LN2 tube is 88.5°K Max Temp at nominal power is 89.0°K

8 Mini-F-Cal Performance with Fewer/Smaller Straps=
