Good point, the shielding would need to be more extensive since the 
gamasource wouldn't be in a small area of the ship.

Super conductors are vulnerable to radiation or high current loads.

That is the thrust transmition mechanism to the ship.

That doesgethr it the ship,it  gets it into  pion stream.  I.E. the kinetic 
energy of particals going one way is balenced by those going the other.  It 
does NOT get thrust into the ship.
