Three-gradient Emittance Measurements at REX-ISOLDE

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. For a 2.85 MeV/u beam with A=q = 4 the rms normalised emittance was measured as 0:32 0:06 mm mrad with the three...

description 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. For a 2.85 MeV/u beam with A=q = 4 the rms normalised emittance was measured as 0:32 0:06 mm mrad with the three-gradient method, a factor of 5 larger than was measured by the NTG emittance meter. An investigation into the discrepancy and a hypothesis for its cause are detailed in this note.
