“…With the advancement of rare-isotope beam (RIB) facilities [8], access to increasingly exotic radioactive nuclei has become possible, allowing for a variety of decay experiments on short-and long-lived nuclei. Modern decay spectroscopy devices employ multiple detection systems for both charged particles and photons to further increase the sensitivity of the experiment, thus allowing for the observation of weak signals [9].…”

“…The Isotope Separator and Accelerator (ISAC) facility [20,21] at TRIUMF in Vancouver, Canada, employs a high-intensity (up to 100 µA) beam of 500 MeV protons to produce RIBs using the isotope separation on-line (ISOL) technique [8,22]. ISAC is currently able to provide a wide variety of RIBs through the use of several different production target and ion-source combinations [23], including the recent use of uranium-carbide (U C x ) targets [23].…”

“…The commissioning of the decay-spectroscopy apparatus was performed using six Si(Li) detectors and one highpurity germanium (HPGe) detector in the seven access ports of the EBIT 8 . In addition to testing the array with on-line radioactive beam, the goal of these measurements was to characterize and examine the capabilities of the setup by observing the EC decay of 124 Cs [36,37].…”

A novel in-trap decay spectroscopy facility has been developed and constructed for use with TRIUMF's Ion Trap for Atomic and Nuclear science (TITAN). This apparatus consists of an open-access spectroscopy ion-trap, which is surrounded radially with up to seven low-energy planar Si(Li) detectors. The ion-trap environment allows for the detection of low-energy photons by providing backing-free storage of the radioactive ions, while guiding decay particles from the trap center via the strong (up to 6 T) magnetic field. Excellent ion confinement is also facilitated by the use of an intense electron beam which provides storage times of minutes or more without ion loss. These advantages, along with careful monitoring and control, provide a significant increase in sensitivity for the detection of X-rays from the electron-capture process. The design, development, and commissioning of this apparatus are presented and the future of the device and experimental technique are discussed.Keywords: in-trap decay spectroscopy, electron capture, beta-decay of highly-charged ions, X-ray detection, electron-beam ion trap, nuclear matrix elements, double beta decay

“…TITAN resides at the Isotope Separator and Accelerator (ISAC) facility at TRIUMF, which employs a high-intensity (up to 100 µA) beam of 500 MeV protons to produce RIBs using the isotope separation on-line (ISOL) technique [10]. The mass-selected, continuous beam of radioactive singly charged ions (SCIs) is delivered at low energies (< 60 keV) to a suite of experimental facilities for both cooled-and stopped-beam experiments [15].…”

An in-trap decay spectroscopy setup has been developed and constructed for use with the TITAN facility at TRIUMF. The goal of this device is to observe weak electron-capture (EC) branching ratios for the odd-odd intermediate nuclei in the ββ decay process. This apparatus consists of an upto 6 Tesla, open-access spectroscopy ion-trap, surrounded radially by up to 7 planar Si(Li) detectors which are separated from the trap by thin Be windows. This configuration provides a significant increase in sensitivity for the detection of low-energy photons by providing backing-free ion storage and eliminating charged-particle-induced backgrounds. An intense electron beam is also employed to increase the charge-states of the trapped ions, thus providing storage times on the order of minutes, allowing for decay-spectroscopy measurements. The technique of multiple ion-bunch stacking was also recently demonstrated, which further extends the measurement possibilities of this apparatus. The current status of the facility and initial results from a 116 In measurement are presented.

“…By implanting polarized nuclei in a medium and subsequent detection of its β-asymmetry, valuable information from either, the nucleus or the implantation medium can be inferred. With the recent developments of radioactive beam line facilities [2], the use of polarized nuclei has opened new opportunities to elucidate unexplored physical phenomena in nuclear structure [3][4][5], weak interactions studies [6][7][8][9] and material sciences [10]. At ISOLDE, CERN [11], polarized nuclei can be obtained by applying one of the commonly used techniques: laserinduced nuclear orientation [12], low temperature nuclear orientation [13], or the tilted foils method in combination with the post-accelerated beams from REX-ISOLDE [14].…”

Abstract. By using polarized ion beams in combination with the β-NMR technique, the Versatile Ion-polarized Techniques On-line (VITO) experiment at ISOLDE, CERN links together expertise from different fields in an unique experimental setup. An overview of the experimental techniques and a general description of the newly designed beam line are presented. Potential uses in multidisciplinary research and perspectives for future experiments are discussed.
