AB  - The Decay Spectroscopy Station (DSS) of the Collinear Resonance Ionization Spectroscopy (CRIS) experiment at ISOLDE-CERN has been upgraded to perform isomer-selective β- and γ-ray spectroscopy, including a new tape system to perform spectroscopy, free from residual activity. The baseplate of the detection chamber was redesigned to incorporate the tape, a MicroTOF detector for beam diagnostics, and a custom-made, high-vacuum-compatible plastic scintillator. The vacuum operation reached a stable pressure of 10^−7 mbar in the detection chamber, overcoming vacuum issues from the previous design. Around the detection chamber, up to three high-purity germanium (HPGe) detectors and four LaBr detectors can be installed, giving a total photopeak efficiency of the HPGe detectors of 7% at 200 keV. The implementation of a 24-channel digital DAQ system combines the detection array with the CRIS setup to perform laser-assisted β- and γ-ray spectroscopy. A commissioning experiment with isomeric beams of ^106g,106mIn, purified by narrow-band laser resonance ionization, showed complete removal of activity from the β detector and full separation of the ground and isomeric state of ^106In. An average β-detection efficiency of 19(2)% was determined from the experiment.
