 Three-gradient Emittance Measurements at REX-ISOLDE / Olsson, T ; Fraser, M A ; Lanaia, D ; Voulot, D The transverse emittance was measured using the three-gradient method (also known as the quadrupole scan method) and compared to the slit-grid method that is normally used at REX-ISOLDE.

 Notes on the HIE-ISOLDE HEBT / Fraser, MA The HEBT will need to transfer the beam from the HIE-ISOLDE linac to up to four experimental stations over a wide range of energies from 0.45 MeV/u to 10 MeV/u, which equates to a maximum beam rigidity of 2 Tm for A/q = 4.5.

 Longitudinal Emittance Measurements at REX-ISOLDE / Fraser, MA ; Pasini, M ; Piselli, E ; Posocco, PA ; Voulot, D ; Wenander, F ; Zocca, F The rms longitudinal emittance at output from the REX-ISOLDE RFQ was measured as 0.34 ± 0.08 π ns keV/u and at entry to the 7G3 as 0.36 ± 0.04 π ns keV/u using the three gradient technique; systematic errors are not included but are thought to be approximately 10%.
