Fast front-end and readout electronics

Oral presentation

In the framework of the HISTARS (HIE-ISOLDE Timing Array for Reaction Studies) project at ISOLDE/CERN, it is planned to install a gamma-ray array specifically designed for fast-timing measurements of nuclear states populated in reactions. State-of-the-art inorganic scintillators, such as LaBr$_3$​(Ce) [Vedia2015,Vedia2017,Fraile2020] or CeBr$_3$​ [Picado2017], are commonly used due to their...

16. Redshifted Cherenkov radiation for fast-timing detectors

New detector technologies

Oral presentation

The enhancement of time response in scintillator-based gamma-ray detectors is crucial for applications such as Time-of-Flight Positron Emission Tomography (TOF-PET) and experimental nuclear and particle physics. One promising approach to achieve this improvement is by utilizing Cherenkov radiation, which is emitted nearly instantaneously compared to traditional scintillation light. However, a...

Nuclear structure from fast-timing measurements

Oral presentation

The isotopic chains close to the magic proton number $Z = 50$ have motivated an extensive experimental and theoretical effort during the last decades. Their simple structure provides an excellent ground to study shell-evolution along the chain, as well as to understand the interplay between single particles and collective degrees of freedom. The systematic study of their excited structure, and...

18. Probing the coexistence of nuclear shapes through the first lifetime measurement of the $0^+_3$ state in $^{120}$Sn

Nuclear structure from fast-timing measurements

Oral presentation

The semi-magic $^{120}_{50}$Sn$_{70}$ lies in the neutron mid-shell among the other stable Sn isotopes, where shape coexistence was observed with the signature of deformed bands built on excited $0^+$ states intruding into the yrast band that is built on the spherical ground state. However, the lifetime of the excited $0^+_3$ state only has a lower limit of 6 ps in the literature, which...

Nuclear structure from fast-timing measurements

Oral presentation

Shell evolution around magic and double-magic numbers, such as $^{68}$Ni ($N=40$) and $^{78}$Ni ($N=50$), has always attracted many theoretical and experimental investigations. For this purpose, the experimentalists have been studying a set of observables, as i.e. the first excited 2$^{+}$ state energy and the transition probability between the first 2$^{+}$ states and the ground state,...
