 #### Abstract:
-We present a symplectic Particle-in-Cell algorithm which uses a space coordinate, instead of time, as the independent variable. 
+We present a symplectic particle-in-cell algorithm which uses a space coordinate, instead of time, as the independent variable. 
 The algorithm derives from a Hamiltonian which is obtained from canonical transformation of the relativistic Low Hamiltonian for collisionless plasma.
 This method has the advantage of greatly simplifying simulations such as tracking with space charge throughout an electron gun.
