Summary on Grant Application Form
The programme consist of the upgrade of the existing DIAMANT II array of CsI light-charged-particle detectors, followed by the online exploitation of the device in conjunction with the powerful gamma-ray spectrometers, EUROBALL and EXOGAM. The proposed improvements consist of equipping DIAMANT III with dedicated VXI electronics that use both zero crossing and ballistic deficit correction methods. The use of dedicated VXI electronics will improve the overall performance of the device and will facilitate the integration of the DIAMANT III data acquisition system with the XVI-based systems used with the EXOGAM and EUROBALL arrays. DIAMANT III will have the added flexibility that eight of the most-forward detectors will be interchangeable with the high-granularity Debrecen Chessboard array. This will represent an optimal configuration for experiments using inverse kinematics, where the evaporated charged particles tend to be forward focussed. The primary line of research that will be followed concentrate on the study of proton-rich nuclei, which when produced in nuclear reactions tend to have high probabilities for the emission of light charged particles (predominantly protons and alpha particles), which contrast with low cross-sections for channels involving neutron-emission. The high efficiency of DIAMAN III, especially when augmented with the new VXI electronics, will mean that the device can be used for channel selection near the N=Z line, increasing the effective sensitivity of the EXOGAM and EUROBALL arrays and lowering their limit of observation. DIAMANT III will be extremely useful in the study of states at medium to high angular momentum, where the detection of weak rotational cascades is often hindered by the Doppler broadening of the gamma-ray line-shapes. The Doppler broadening is particularly severe in reactions where emitted protons and alpha particles result in a wide recoil cone for the residual nuclei being studied. DIAMANT III will detect the emitted charged particles and allow measurement of their energies, enabling an event-by-event calculation of the gamma-ray Doppler correlation based on the deduced recoil momentum.
