ValnaoPlease drive carefully: scientists plan to transport volatile antimatter for first time
Paranoid FactoidA few thousand antimatter charged particles could be used as an implosive trigger for a fusion bomb.
you’re off by something like 15-18 orders of magnitude
This is old, but you get the idea. See section 3.5.
Fourth Generation Nuclear Weapons: Military effectiveness and collateral effects
The paper begins with a general introduction and update to Fourth Generation Nuclear Weapons (FGNW), and then addresses some particularly important military aspects on which there has been only limited public discussion so far. These aspects concern the unique military characteristics of FGNWs which make them radically different from both nuclear weapons based on previous-generation nuclear-explosives and from conventional weapons based on chemical-explosives: yields in the 1 to 100 tons range, greatly enhanced coupling to targets, possibility to drive powerful shaped-charge jets and forged fragments, enhanced prompt radiation effects, reduced collateral damage and residual radioactivity, etc.
The paper you linked says “1 microgram is sufficient to trigger one thermonuclear weapon” which corresponds to 6×10^17.
This makes your “few thousand” of by 14 orders of magnitude instead of 15, I bet you feel vindicated now.
For example, a device the size of a hand grenade with tons of TNT equivalent output
A man portable nuke has existed since the 60’s so it wouldn’t be a game changer.
Sure. I just thought it was funny that it looks like the suitcase a cartoon character would put a warhead in.
