I wonder if forcefield bullet shells could be used here. Bullet goes BLAM, forcefield explodes, the projecting material is destroyed, the rod is shattered... and sprayed across the open wound. While still active, because within the minimal size.
Actually, I'm a little fuzzy on how that last part works, but if it requires the fragments be within that size, we could even make those rods bigger - easier for manufacturing and transportation - and then blow them up into little chunks within the size requirements. Instant cooling activation. To think of it, if that method works, we could even upscale it as specialised spaceship ammo against organic space-objects (Haebi, space-wasp (if it's organic), STAN-2, etc.).
@Radio Controlled Would you mind assigning a second science team to some project as well? If you need ideas, there's whole list of suggestions down at the bottom of the Hephaestus wiki page. Also maybe one or two Construction crews. Depending on space-magic-disabling effectiveness, those space-pollen minefields could be very useful as an addition to nuke minefields, for example. Or, if not to trespass on Sean's sphere of influence, they could be assigned to building replacements for the base components disabled by our little Thermophage pet (best built away from the base, if possible). Then even if we have to bomb it into nothingness (or whatever 'final countermeasures' might consist of), the full functionality of the base won't be disturbed.
