Heatspot

Just then another sensor pinged; a heatspot on the exterior hull, not far from the stasis switch. Not very hot, only enough to vaporize iron, but it might be a guide beam for some weapon that would penetrate shipmetal.

As pointed out by Faubel and Ali (1986), the use of undiluted APM in a column mode is difficult because of the microcrystalline structure of the material and because of the potential need to provide a cooling system to prevent heatspots from the radiolytic heat generation.
