68. Single-neutron properties of nuclei probed with the ISOLDE Solenoidal Spectrometer

David Sharp (University of Manchester (GB))

Invited (In person)

The ISOLDE Solenoidal Spectrometer was fully commissioned in 2021 with the new silicon array developed by the University of Liverpool installed. This array makes use of double-sided silicon strip detectors, with ASIC readout, to determine the position of interaction and the energy of light ejectiles when they return to the beam axis following reactions of HIE-ISOLDE accelerated beams with a...

1. Characterisation of the SpecMAT active target at ISOLDE and its physics perspectives

The SpecMAT active target will be used to study shell evolution in exotic isotopes and investigate the fundamental aspects of the nuclear structure far from stability via transfer reactions in inverse kinematics. The SpecMAT is currently at the final developmental stage and undergoes characterisation measurements at KU Leuven and ISOLDE. During the most recent characterisation, SpecMAT was...

55. Elastic alpha scattering on heavy exotic nuclei - report on IS698 experiment

Daniel Galaviz Redondo (LIP - Laboratorio de Instrumentação e Física Experimental de Partículas (PT))

Submitted oral (In person)

The uncertainties in the knowledge of the alpha-nuclear potential are still one of the main sources of uncertainty in the modeling of the production of the stable p-nuclei, with those uncertainties extending to unstable proton rich regions of the nuclear chart.

Recent developments in the production of thin silicon films containing large amounts of He allowed for the proposal of the first...

7. Neutron measurement in the IS581 experiment

Martin Veselsky (Czech Technical University in Prague (CZ))

01/12/2022, 15:00

Submitted oral (In person)

Four Timepix3 pixel detectors were installed
on the body of Actar TPC demonstrator during
the November 2021 beamtime of the IS581 experiment.
Polyethylene converters were used for detection
of fast neutrons. Since no significant background
was observed, it was possible to measure the angular
distribution of emitted neutrons. Subsequent simulations
emplying the results of Talys code and...

8. ASET: the new α- decay setup and much more

Silvia Bara (KU Leuven (BE))

01/12/2022, 15:15

Invited (In person)

ASET, α-setup, is a new detection system designed and built to perform particle decay spectroscopy at ISOLDE. It is based on a movable ladder system instead of a wheel, previously used in the Windmill system $^{[1]}$. The working principle is the same as Windmill’s: the ladder moves up and down between two silicon detectors (an annular and a full one), which are placed at each side of the...
