    what would be the poyinting vector of beam of charged particles moving in +ve x-direction.
    S=ExH
    calculating H is fine but how to calculate the E

    The poynting vector is a property of the electromagnetic field, it is not a property of particles.
    If you have a continuous beam you get the same electric field as from a charged wire: radially outwards.
