The linac of the SNS accelerator facility can be used to produce an electron beam with 300-400 MeV energy. At present there are a few predesigned experiments with electron beam that can be alternatively carried out at the SNS. However, the SNS linac is designed and optimized for acceleration of H⁻ , which brings some problems when considering direct acceleration of electrons. Alternative machine setup for electron acceleration and transport are discussed. Here, we present a study of the optimal electron beam parameters that can be achieved without any significant changes of the SNS accelerator.

We report on the world’s first experiment of a parallel profile scan of the hydrogen ion (H⁻) beam using a laser wire system. The system was developed at the superconducting linac (SCL) of the Spallation Neutron Source (SNS) accelerator complex. The laser wire profile scanner is based on a photo-detachment process and therefore can be conducted on an operational H⁻ beam in a nonintrusive manner. The parallel profile scanning system makes it possible to simultaneously measure profiles of the 1-MW neutron production H⁻ beam at 9 different locations (corresponding to energy levels of 400 – 950 MeV) of the superconducting linac using a single light source. The entire measurement process takes less than 5 minutes to complete. Together with the hardware modification, we have also upgraded our user interface to visualize the 9-pairs of H⁻ beam profiles in a real-time fashion, which presents a highly intuitive and informative picture of the H⁻ beam propagation along the acceleration path. The laser wire based parallel profile scanning system provides a powerful tool for accelerator operators and physicists to study the SCL modelling, monitor and/or tune the beam parameters.
