“…The barrel spans the angular range from 35.6 • to 143.4 • . The position resolution is better than 0.5 mm (fwhm) for α-particles of 5.5 MeV [11] and somewhat poorer for smaller deposited energies, and the energy resolution is 120 keV. Beyond the barrel, the forward angles are covered by nested annular double-sided strip detectors, one spanning 12.8 • -28.1 • and the other, more distant annulus covering more forward angles down to 3.8 • .…”

The first physics results measured using the TIARA array are reported. The reaction 24Ne(d,p)25Ne has been studied in inverse kinematics with a radioactive beam of 24Ne provided by SPIRAL at GANIL. TIARA is very compact with a high geometrical coverage for charged particles, and is designed specifically for the study of transfer reactions in inverse kinematics, with radioactive beams. From the (d,p) differential cross sections, the ground state of 25Ne is assigned to have Jπ = 1/2+ and the lowest states with Jπ = 5/2+ and 3/2+ are tentatively identified at excitation energies of 1.70 and 2.05 (±0.05) MeV, respectively. Coincident gamma-ray data proved essential to resolve these two excited states. Strongly populated levels observed at 3.30 and 4.05 (±0.05) MeV are candidates for negative parity states. Further analysis of the differential cross sections is in progress, with the aim of improving the identification of the higher lying states and determining absolute spectroscopic factors.

“…It was designed to be used in combination with the MINIBALL γ-detector array [3], allowing the reconstruction of the excitation energy in the final nucleus with a better resolution than it could be obtained with particle spectroscopy alone. The setup is comparable with other devices such as TIARA [4,5], SHARC [6], and ORRUBA [7].…”

Transfer reactions in inverse kinematics using the radioactive ion beams provided by the REX-ISOLDE facility at CERN are very good tools to gain insight into the single-particle properties of exotic nuclei. The new silicon particle detector setup T-REX, optimized for these transfer reactions, is presented in this article. T-REX consists of position sensitive ΔE-E telescopes in a compact configuration that covers up to 66% of the solid angle. The setup allows the identification of the light reaction products and the measurement of their angular distribution for a large range of polar angles. Simultaneous detection of the elastically scattered target-like nuclei enables the determination of the optical model parameters used in the analysis of the experiments.

“…This method removes the ambiguity regarding multiple crossing points, which is a feature of DSSDs, and leads to clearer measurements of coincident particles with similar energies, if they strike separate strips. The charge division method has been shown to give superior position resolution compared to the DSSD strip width [9] but this is strongly dependent on the noise environment and the energies of the detected particles [10]. For high energy particles, a position resolution of 0.1 mm has previously been obtained.…”
