Assuming we can make a field strong enough to reflect the particles at all.

Does anyone know how and if this problem can be solved?

Yes, but when you decrease the amount of particles that are released, the
pressure build up is slower. This makes that the equilibrium pressure goes
down too.
Imagine a funnel in which you pour water. If you pour only a little bit of
water all goes out slowly without building up a waterlevel in the funnel. If
you pour more water, then the waterlevel in the funnel starts to rise and
the velocity of the water that comes out of the funnel increases with the
height of the waterlevel. If you pour too fast the funnel will flow over.
The level of the water can be compared with the pressure in the engine, the
amount of water poured in cna be compared with the amount of particles
(photons) released by the fusion reaction.
