The versatile design of IDS allows for the installation of different types of detector around the implantation point, alongside its own four HPGe clovers. It can hence be used for many specialised decay measurements, including fast-timing, neutron time-of-flight, angular correlation, charged particle spectroscopy and conversion electron spectroscopy (using the newly employed SPEDE detector).
The Decay Station is an ideal tool for studying the decay properties of radioactive nuclei across the Segré chart; light to heavy, proton-rich to neutron-rich. The nucleus of interest is only limited by the production capabilities of the targets at ISOLDE.
While the four HPGe clovers are used for most experiments at IDS, the addition of other HPGe detectors allows for increased statistics when performing gamma ray spectroscopy. Two openings in the holding structure (shell) at 90 degrees to the beamline, and a third located coaxially, in the horizontal plane may be used to position plastic beta detectors (two located here at IDS) or fast-timing detectors. The detector chamber itself may be changed according to the needs of the experiment, as may be the contents (such as DSSDs for particle detection). Since 2016, a dedicated neutron time-of-flight detector is permanently located at IDS (IDSND) and is based on the VANDLE (University of Tennessee, Knoxville, USA) detector design.
IDS is supported by 13 institutes across Europe, and used by many more globally.
