| TUPLH03 | Double-Bend Achromat Beamline for Injection Into a High-Power Superconducting Electron Linac | 494 |
|

| To take advantage of the high duty cycle operation of superconducting electron linacs, commercial systems use thermionic cathode electron guns that fill every RF bucket with an electron bunch. In continuous operation, the exit energy is limited when compared to pulsed systems. Bunch length and energy spread at the exit of the gun are incompatible with low losses in the superconducting cavity. A solenoid double-bend achromatic beamline is in operation at Niowave which allows energy and bunch length filtering of the beam leaving the gun before injection into the superconducting cavity. This system uses two solenoids and two dipoles to produce a round beam, using the edge angles of the dipoles to balance the focusing effects in the two transverse planes. The design allows beam filtering on the symmetry plane where the dispersion is maximum. Additionally, the bend angle moves the electron gun off the high-energy beam axis, allowing multiple-pass operation of the superconducting booster. This contribution will discuss the beam optics design of the double-bend achromat along with the design of the magnets and beam chambers and the operational experience with the system. | ||

| Because of advances in niobium cavity resonator design and the continuing development of small helium cryocoolers, superconducting RF linacs have become a viable industrial technology for low-cost, high-power electron beams. These beams are being used to produce high-flux bremsstrahlung x-ray and neutron sources for commercial applications, particularly for the production of radioisotopes. This contribution will cover recent developments in commercial superconducting accelerator technology including thermionic cathode electron guns, superconducting cryomodules, helium cryocoolers, microwave sources, and target stations for the production of medical and industrial isotopes including molybdenum-99 and actinium-225. Machines at different stages of development span the energy range from 2-40 MeV and powers up to hundreds of kW. Connections will be made to high-power machines for high-throughput x-ray sterilization and accelerator-driven systems with electron beams. | ||
