Nuclear fusion can only happen if you can get the components close enough together and hot enough.

Very close.
A small fission bomb goes off and the energy from this heats the outer casing of the fusion bomb. This casing then emits intense X rays which in turn heat a the outside of the 'real' fusion core which is made of berylium which absorbs X rays and reflects neutrons. This causes the outside of the core to rapidly expand and causes immense heating and compression of the De/Tr. When it is hot enough a triggering device emits a quick blast of neutrons which kick starts the fusion. The tricky part is getting the bomb to hang together long enough for all this to happen.
The reason for the indirect heating by X rays is to get a uniform implosion of the core. Just putting it next to the fission bomb would heat one side more than the other and reduce the compression.
Don't try this at home folks.
(My nuclear physics course at university seemed to have an unhealthy focus on neutron capture cross sections and things that go bang)

The x-rays transfer energy to the hydrogen which causes it to heat up. When it reaches the required temperature the fusion reaction should take place. I'm not a weapons expert so I can't tell you how they focus the x-rays.

in a hydrogen bomb fission bomb explodes first,the high temperatures resulting from this (of the order of 300,00,000 degrees centigrade)cause the fusion of tritium ,He3 ,deuterium mixture enclosed around core of fission bomb.Very high energy gets released in fraction of second.
In controlled fusion reactions high temperatures required are attained through pulsed LASERS of very high frequency(x-ray frequencies).The confinement of fusion material is done with magnetic fields.

Nuclear fusion is 2 atoms fusing together. This takes temperatures of around 120000 degrees Celcius.
In a nuclear bomb it is nuclear fission, a different matter altogether.

PRODUCTION OF X RAYS:x rays have nothing to do with nuclear reaction
x rays are produced when a beam of fast moving electron strike an element of high atomic no and at. mass.generally the target element is taken as tungsten or thoriated tungsten
X RAYS show all the phenomenon which light rays show like diffraction refraction .surely they can be bent using non uniform electric field. it acts like a lens for it
nuclear fusion is major source of energy for all stars like sun whose major component is hydrogen whose atomic no is lowest so no chance of production of x rays for initiation of nuclear reaction by means of x rays
due to extreme gravitational pull of gases in vacuum space and frequent collision of gas molecules create high temp of order 10 to power of 5
this causes nuclear fusion reaction to start once started enormous amount of energy is liberated which further leads continuation of reaction till the fuel that is hydrogen get used up.
I WROTE ALL THIS TO EXPLAIN TO YOU THE THING REQUIRED TO INITIATE NUCLEAR FUSION REACTION THAT IS VERY VERY HIGH TEMPERATURE
THEY MIGHT BE TRYING TO HEAT THEM BY FREQUENT COLLISION WITH X RAYS
ACTUALLY TO COLLIDE THEM FIRST THEY ARE ACCELERATED BY PARTICLES ACCELERATORS LIKE CYCLOTRON, CYCLO SINCROTRON WHICH PROVIDE HIGH ENERGY TO THEM AND ON COLLISION CAUSE INITIATION OF NUCLEAR FUSION REACTION

it's a kind of weapons people use it for wars and fight between two countries about for example (oil,gaz,bomb,water,or a city near to the other country mapor and they used to kill the animals like dinosaurs,momiyah ect...
