How long to activate the Jump Drive?

[MasterGwydion]

Note that the bubble T5 refers to is a bubble of our normal spacetime and quantum fields - this bubble of normal space is maintained by the hull.

It is not hydrogen filled, it is a vacuum of four dimensional spacetime and the fundamental quantum fields of our universe maintained as a bubble of the quantum foam that makes up the jump dimensions.

In T5 the hull grid wiring maintains the normal universe field conformal to the hull and a metre or so extended beyond it. It is a field, not a bubble of hydrogen.
The jump bubble version extends the normal space bubble as a sphere around the ship, but again it is a field that maintains our normal space within, and once again it is not filled with hydrogen.

Not filled with, used to create.

No, there is no hydrogen used to create the bubble. The hydrogen is used to generate the energy necessary for the jump drive to create the field that interacts with jump space dimensions.
In an antimatter powered jump drive it is the generation of energy from the matter/antimatter rection that is used to generate the field.

The collector works somewhat differently, it is not a big photovoltaic cell. It somehow interacts with the particle expression of the jump field interaction and when its 'jump accumulators' are filled it may then initiate jump.

When I originally posed the exotic particles idea I said they were generated by stars to order to model the original Annic Nova. Since the retcon to collectors in MgT/T5 then I would have to handwave interaction with the quantum fields that fill even the vacuum of space - proximity to a star no long appears to matter.

MgT2 CRB 2022 seems to contradict you. Page 157 states,

Jump travel is the only known means by which a vessel
may travel faster than light. To jump, a ship creates
a bubble of hyperspace by means of injecting highenergy
exotic particles into an artificial singularity. The
singularity is driven out of our universe, creating a tiny
parallel universe that is then blown up like a balloon
by injecting hydrogen into it. The jump bubble is folded
around the ship, carrying it into the little pocket universe.

Hydrogen is injected into jumpspace blowing it up like a balloon, not converted into power. It has been different in other versions, but this is the current MgT2.

To reiterate, speculative.

Simply, it looks like we're trying to fit the pieces given into a coherent jigsaw picture.

That is actually exactly what I am trying to do...lol...

The 2022 quote is contradicted by the words of MWM himself. His jumpspace article should be the reference for how things work in the OTU, it is even part of MGT canon. The author of the 2022 quote should have done better research.

I have quoted the relevant sections from the MWM article, hydrogen is only used to generate the power for the jump - there is no hydrogen filled bubble, that particular trope developed from a misunderstanding of what was written in the MegaTraveller Starship Operators Manual which first describes the jump field as a bubble of normal space. I think it was FF&S that first mentions using a small amount of hydrogen being used to 'prop up' the bubble, but this is directly in contradiction to MWM;s article, T5, and the way collectors and antimatter poered ships jump without hydrogen.

It is pretty galling to see the rules diverge from their own canon. Since MWM decides what is canon for his setting then within the Third Imperium jump works the way he describes in his article, not in a bit of misunderstood contradictory fanon/canon.

The 2022 quote and MWM's article can't both be correct, and I tend to side with MWM if he has a definitive version.

Still at the end of the day it is a game and such discussions shouldn't get in the way of people enjoying their games.

I look forward to the updated version of HG to see if they reconcile collectors and anti matter powered ships being able to jump without hydrogen.

I won't disagree with that at all, but unless they change it up in High Guard, then it is what it is.

I agree with you
