| description | To optimize the performance of the Collinear Resonance Ionization Spectroscopy (CRIS) experiment at CERN-
ISOLDE, technical upgrades are continuously introduced, aiming to enhance its sensitivity, precision, stability,
and efficiency. Recently, a voltage-scanning setup was developed and commissioned at CRIS, which improved
the scanning speed by a factor of three as compared to the current laser-frequency scanning approach. This
leads to faster measurements of the hyperfine structure for systems with high yields (more than a few thousand
ions per second). Additionally, several beamline sections have been redesigned and manufactured, including
a new field-ionization unit, an electrostatic bend with a larger deflection angle, and improved ion optics. The
beamline upgrades are expected to yield an improvement of at least a factor of 5 in the signal-to-noise ratio by
avoiding the use of high-power lasers (which yield non-resonantly produced ions) and providing time-of-flight
separation between the resonant ions and the collisional background. |
