An alternate design:

Build the system as a rapidly rotating disk, with a moderately high
operating temperature. You have lots and lots of holes in the disk
(slanted, obviously), each with an associated ring of coolant material. The
heat exchange tunnels will be very hot (a few thousand degrees), while the
coolant will be very cool (use a big orbit so it has time to cool off).

Also, you should imbed something ferrous in the particles so that you can
manipulate the stream magnetically. That way a mass driver system
integrated with each tunnel can adjust the coolant vectors to correct for
the inevitable orbital instabilities (assuming they aren't too big).

I would assume an SI can easily solve any engineering problem that does not
violate the laws of physics. Therefore, it seems reasonable to assume that
it can find some clever means of quickly dumping heat from the tunnel to the
coolant stream. (Mind you, I'd still like to think of a good solution to
the problem - I just think we shouldn't expect it to b a show-stopper if we
don't come up with one.)
