Thermal Analysis TF Coil Cooling |
Dahlgren (Kalish) |
The TF Thermal
Analysis assumes a flow rate and calculates maximum temperatures and
cool down time. The analysis has been updated to reflect the 3x4
winding pack. |

Comparative Stress Analysis of the Reference and Narrow (3.47”) NCSX TF
Coils |
Myatt (Brooks) |
This was an
earlier analysis that provided the basis for the change to the 3x4 from
the 2x6 winding pack. It is included in the final list of reports
only because it provides us with the basis to conclude that the .5 Tesla
case is in fact our benchmark for evaluating worst case stresses. It
analyzes the TF coils subject to fields from all other coils for each of
the required cases. This analysis uses a coarse mesh and does not
provide final stress and deflection results. Using the .5 Tesla case as
the basis for further analysis allowed us to move forward with a simpler
TF only model with greater resolution for optimization of the wedge
castings and determination of the stress. This model was not updated to
reflect the new Kapton on copper insulation scheme. |

Stress Analysis of the 3x4 Slip-Plane TF Coil with Cast SS Wedges |
Myatt (Brooks) |
This document
contains the final stress analysis for the TF Coil. Only the .5
Tesla case is considered. It is a hybrid model in that it uses smeared
winding pack properties in the low stress regions of the coil but has a
detailed winding pack model where the peak stresses occur. The analysis
was also used to optimize the casting design and includes stress
analysis in the casting. Fatigue analysis is included. |

Deformations in the NCSX TF Coil from all Field Sources and a Simplistic
Linear Model |
Myatt (Brooks) |
This analysis was
necessary to satisfy the max. displacement criteria for the coils.
Each load case is evaluated using a smeared winding pack model that
includes all of the coils. Coil restraints and preload are applied for
the TF "pushers", vertical supports, and wedge castings. The deflection
output file was provided to Art Brooks who performed an Island Study and
concluded that the deflections due to each of the operating scenarios
are within acceptable limits. See: "Island
Study Results from Revised smeared TF 3x4 with slip plane 12-20-04"

Calculating Smeared
Properties of the TF Winding Pack for Use in Global Models |
Myatt (Brooks) |
This analysis
provides the “smeared winding properties” required as input to all other
models. It has been updated to reflect changes in the coil cross
section and insulation scheme. The properties determined by this model
were benchmarked in the analysis by modeling two beams. One using the
smeared properties and one with complete conductor and insulation
detail. The smeared properties were then adjusted until the deflection
in bending of both the beams matched. This analysis will also be the
basis for the beam testing that we are undergoing.

Radial Preload Requirements for TF Coil
Structural Continuity, 3x4 TF Array Plus Wedges |
Myatt (Brooks) |
The wedging analysis
uses inputs from Art Brooks that provide the worst case magnetic
ejection loads to the TF Coils. The analysis does indeed show that there
can be a net outward radial load on the TF Coils. This result is the
basis for the Pusher Structure and is used to size the inward preload
requirement. |
