VECC array for Nuclear fast Timing and angUlar corRElation studies (VENTURE)

Abstract The VE CC array for N uclear fast T iming and ang U lar cor RE lation studies (VENTURE) has been developed using several fast Cerium-Bromide (CeBr 3 ) scintillators coupled to Hamamatsu R9779 Photomultiplier tubes. The CeBr 3 detector has been characterised for the spectroscopic properties like energy response, energy resolution, timing resolution and detection efficiency. The response and efficiency of the detector have been compared with the results obtained from a Monte Carlo simulation with GEANT3 package. A time resolution of 144(1) ps and 109(1) ps was obtained for a single detector using 622–512 keV and 1173–1332 keV cascades respectively. The Generalised Centroid Difference (GCD) method has been employed with CeBr 3 detectors by measuring the level lifetimes for the 511.9 keV level of  106 Pd and the 160.6 and 383.8 keV levels of  133 Cs. The angular correlation measurement was performed for the 1173–1332 keV cascade in  60 Ni and the 228–49 keV cascade of  132 I nucleus, populated from the decay of  132 Te produced via  238 U( α , f) reaction.
