“…The curve shown in Fig. 11 is similar to the one obtained from a measurement performed at Argonne National Laboratory in which the same detectors and electronics were used [32]. The mean lifetime is measured to be 2.046(43) ns using an exponential fit to the slope.…”

“…The time walk, or residual time walk, that still persists after the signal has been discriminated in the CFD, is a very important characteristic for the application of the centroid shift method. Applying this method, lifetimes down to less than 10 ps can be measured bydelayed coincidence using the FATIMA array [32]. For this purpose the prompt response curve (PRC) of the system, i.e.…”

The FATIMA detectors described in this paper were used, for example, at Argonne National Laboratory with Gammasphere [32] (see Section 4.1), at GANIL with AGATA and VAMOS [37], at the IPN Orsay with Stella [38] (see Section 4.2) and in the beginning of the -Ball campaign [39][40][41], and at RIKEN during the EURICA campaign [42,43]. In all these cases the detectors were fixed in place using custom designed clamps.…”

The components, working principle and characteristics of FATIMA (FAst TIMing Array), a fast-timing detector system for DESPEC at FAIR, are described. The core system includes 36 LaBr 3 (Ce) scintillator detectors, a mounting frame for the DESPEC station and a VME-based fast-timing data acquisition system. The current electronic timing circuit is based on V812 constant fraction discriminators and V1290 time-to-digital converters. Gamma-ray energies are measured using V1751 digitisers. Characteristics of the core FATIMA system including efficiency, energy, and coincidence resolving time, as well as limitations, are discussed on the basis of test measurements performed in the S4 cave at GSI, Germany. The coincidence -time resolution for the prompt 60 Co cascade is determined to be ∼320 ps full width at half maximum. The total full energy peak efficiency at 1 MeV for the 36 detector array in the DESPEC setup is 2.9%. The energy-dependent prompt response centroid curve with the current CFD/TDC combination is shown to be smooth; the centroid shift method can be applied for the measurement of half-lives below 200 ps. An overview of applications of the FATIMA detectors as an ancilliary system in combination with other detector arrays during recent years is given. Data on the operation of the detectors in the presence of magnetic fields are presented.

Gamma-ray spectroscopy of fission fragments with state-of-the-art techniques

2022

View full text Add to dashboard Cite

The paper reviews recent developments in $$\gamma $$ γ -ray spectroscopy of the neutron-rich fragments produced in nuclear fission. This subject has been an intensive area of study spanning more than five decades. Here we highlight key results and describe the evolution of the associated experimental techniques since the last review papers in 1995 (I. Ahmad and W.R. Phillips, Rep. Prog. Phys. 58(11), 1415 (1995); J. H. Hamilton et al., Prog. Part. Nucl. Phys. 35, 635(1995)). Research themes in nuclear structure will be explored along with the fission reaction mechanism and the links to nuclear astrophysics and applications.
