▪ The Jefferson Laboratory's superconducting radiofrequency (srf) Continuous Electron Beam ... more ▪ The Jefferson Laboratory's superconducting radiofrequency (srf) Continuous Electron Beam Accelerator Facility (CEBAF) provides multi-GeV continuous-wave (cw) beams for experiments at the nuclear and particle physics interface. CEBAF comprises two antiparallel linacs linked by nine recirculation beam lines for up to five passes. By the early 1990s, accelerator installation was proceeding in parallel with commissioning. By the mid-1990s, CEBAF was providing simultaneous beams at different but correlated energies up to 4 GeV to three experimental halls. By 2000, with srf development having raised the average cavity gradient to 7.5 MV/m, energies up to nearly 6 GeV were routine, at 1–150 μA for two halls and 1–100 nA for the other. Also routine are beams of >75% polarization. Physics results have led to new questions about the quark structure of nuclei, and therefore to user demand for a planned 12 GeV upgrade. CEBAF's enabling srf technology is also being applied in othe...

This undulator replaced the first Aladdin undulator, which was on loan from the Stanford Synchrotron Radiation Laboratory and had been in use since 1986 ͓K. Halbach et al., IEEE Trans. Nucl. Sci. NS-28, 3136 ͑1981͒; H. Winick et al., Nucl. Instrum. Methods Phys. Res. A 208, 127 ͑1983͒; M. A. Green et al., Nucl. Instrum. Methods Phys. Res. A 266, 91 ͑1988͔͒. The new undulator was designed, constructed, and tested by Danfysik ͑Danfysik A/S, Moellchaves 31A, DK-4040 Jyllinge, Denmark͒. The undulator uses NdFeB permanent magnets for the magnetic structure and is 3.52 m long with 50 periods, each of 68.3 mm. The new undulator is intended to provide high flux from 7.8 to 500 eV. To cover this wide energy range we use the first through ninth odd harmonics. The magnetic structure has been phase-corrected to better than 2°rms and should provide fidelity better than 90% through the ninth harmonic. The resulting undulator flux will support an extreme ultraviolet nano-lithography beamline, a low energy Wadsworth beam line, and a high energy VLS-PGM beam line. Some coherence experiments are also anticipated. The undulator radiation has been analyzed using an existing HTM ͓M. C. Hettrick, Nucl. Instrum. Methods Phys. Res. A 266, 404 ͑1988͔͒ monochromator, a durable filter-pinhole detector, and computer controlled, cooled, scanning apertures. We present measurements of the undulator harmonic content, energy and spatial structure of the undulator beam, and undulator beam position stability.
