| Abstract | The neutron scattering community has endorsed the need for a high-power ( 1 to 5 MW) accelerator-driven source of neutrons for materials research. Properly configured, the ยท accelerator could produce very short (sub-microsecond) bursts of cold neutrons, said time structure offering advantages over the continuous flux from a reactor for a large class of experiments. The recent cancellation of the ANS reactor project has increased the urgency to develop a comprehensive strategy based on the best technological scenarios. Studies to .date have built on the experience from ISIS (the 160 kW source in the UK), and call for a high-current (approx. 100 rnA peak) Hsource-linac combination injecting into one or more accumulator rings in which beam may be further accelerated. The 1 to 5 Ge V proton beam is extracted in a single tum and brought to the target-moderator stations. The high current, high duty-factor, high brightness and high reliability required of the ion source present a very large challenge to the ion source community. A workshop held in Berkeley in October 1994, analyzed in detail the source requirements for proposed accelerator scenarios, the present performance capabilities of different Hsource technologies, and identified necessary R&D efforts to bridge the gap. |
