Argonne is developing the design for an advanced super pulsed-spallation neutron source called ASPUN that uses a fixed-field alternating-gradient accelerator as the proton source. ASPUN is intended to be the next generation in pulsed spallation neutron sources. The spallation source concept was pioneered at ANL, an effort which has led to the successfully operating Intense Pulsed Neutron Source (IPNS). IPNS uses a 500-MeV rapid cycling synchrotron as the proton source. Beam is extracted at a 30-Hz rate onto a depleted uranium target in 100-nanosecond bunches to produce intense bursts of neutrons for solid state physics experiments. The IPNS accelerator routinely delivers greater than 12 ..mu..A of timed-averaged proton current on the uranium target. Newer, more powerful pulsed spallation sources are nearly ready to start operation. The Proton Storage Ring at the Los Alamos National Laboratory is designed to deliver 100-..mu..A at 800 MeV in 12-Hz bursts and the Spallation Neutron Source at the Rutherford-Appleton Laboratory in England is designed to deliver 200-..mu..A at 800 MeV in 50-Hz bursts.
