in a series I am working on I will be using a D-He3 fusion drive system (similar to the one in the expanse according to Project RHO). I am under the assumption that the fuel will be stored in a pellet form that will then be "injected" into the engine where a powerful laser will compress it until fusion occurs. (If this is not the case then please clarify).

The question: what is the density of such a pellet? As a reference, how much of this could be stored within a cubic meter?

    $\begingroup$ People actually make these for laser fusion experiments I think. These are unfortunately paywalled but it's a start 1, 2, this one is not paywalled: 3 $\endgroup$ – uhoh May 28 '20 at 2:49

    $\begingroup$ That is one of my posts for a different aspect I'm trying to figure out. $\endgroup$ – Markitect May 28 '20 at 4:09

    $\begingroup$ Seems possible that you might fabricate pellets as you go. $\endgroup$ – ikrase May 28 '20 at 11:08
