The longitudinal acceptance of the Spallation Neutron Source superconducting linac is computed with a model. A beam current monitor and loss monitors are utilized in new measurement technique, measured results show close agreement Based on simulations measurements acceptance, we developed novel method to measure bunch shape, energy profile, emittance at entrance linac. experimental reveal that large halo exists injected linac, rms approximately twice nominal design. simple applicable other linacs.
