["Instructions"]
["- General:  Enter values in yellow cells only; other values are calculated automatically based on your input."]
["- Row 2:  Change \"Geometry\" to match your plasma's geometry by selecting from the pull-down menu in cell C2."]
["- Rows 3-4:  Set dimensions of plasma.  For imploding concepts, use dimensions at stagnation."]
["- Rows 6-8:  Fill in your aspirational, projected plasma parameters at reactor conditions. Note that thermal diffusivity is in the dominant direction of energy loss."]
["- Rows 12-16:  Fill in the requested dimensions listed in B12-B16 of your volumetric system; enter 0 for subsystems not needed in your concept."]
["- Row 14:  Set \"Liner thickness\" to 0 unless it is required to compress your fuel to fusion conditions, e.g., for an imploding-liquid-liner concept. Please indicate your material, unit cost, and source in cells A14, E14, and F14, respectively.  FLiBe is given as an example."]
["- Rows 18-21:  Fill in the requested information for \"Subsystems.\"  Enter 0 in column C if not applicable for your concept."]
["- Row 21:  Add other subsystems that are each >5% of total cost, such as for plasma formation, stability control, cooling, power exhaust, etc.  Cite your sources in the \"source\" column. Use Sheffield if possible for consistency."]
["- General: If necessary, please make needed changes, such as to unit costs or other fields. Please justify your changes in the \"Unit-cost source\" column and/or in cell A44."]
