The LPC Caen, in collaboration with CIEMAT (Madrid), is developing a new neutron time-of-flight array for structure studies, in particular the investigation of beta-delayed neutron emission from neutron-rich nuclei.
Our aim is an array with improved performance compared to existing arrays, with emphasis on better energy resolution, lower neutron energy threshold, and strong background...

The interest and study of nanomaterials has grown considerably in recent years due to promising applications in everyday’s life technologies. With its relevance depending on tunable properties working at large-scale integration devices, a new battlefield is created since; small scale rules both new properties and new problems. By merging nanostructures with thin film technologies advantageous...

The Collinear Resonance Ionization Spectroscopy (CRIS) experiment at ISOLDE uses laser radiation to stepwise excite and ionize an atomic beam for the purpose of ultra-sensitive detection of rare isotopes, and hyperfine structure measurements. The resonance ionization technique offers the ability to purify an ion beam that is heavily contaminated with radioactive isobars (including the ground...

Development of the hot-cavity laser ion source is planned for the RISP ISOL facility to obtain pure ion beam. Recently, the laser system has been installed, and now the off-line test chamber is being designed. The laser system is composed of four tunable Ti:sapphire lasers (light sources for ionization), and one high power Nd:YAG laser (pump source of Ti:sapphire crystals). In the RISP ISOL...

In-beam spectroscopic techniques have long been one of the most prominent tools in our effort to
disentangle and interpret complex nuclear structure phenomena. In heavy nuclei, where internal
conversion increasingly competes with γ-ray emission, the simultaneous study of γ rays and
conversion electrons can provide a much more complete image than either of them
independently.
The SPEDE...

The one-atom-thick crystal - graphene, uniquely combines extreme mechanical strength, exceptionally high electronic and thermal conductivities, as well as many other exotic properties, all of which make it highly interesting for fundamental physics and numerous applications.
The aim of this work is to use radioactive ad-atoms attaching to graphene to investigate several aspects:
The first...

Rare Isotope Science Project (RISP) aims to construct world-class Rare Isotope Facility named “RAON” consisting of both Isotope Separation On-Line (ISOL) and In-flight Fragment (IF) facilities. The main goal of the ISOL facility is to deliver high quality intense neutron-rich beams to the experimental hall with a beam intensity of ~105–109 particles/sec in the mass range of 80 < A < 160, using...

Collinear laser spectroscopy provides a powerful high-resolution method for the investigation of the nuclear structure of the exotic nuclei. In combination with bunched ion beams a very high sensitivity can be reached. The hyperfine spectra of 48-51K (Z = 19) isotopes were observed at ISOLDE (CERN) for the first time. For this purpose, the CW laser was set to the 4s 2S1/2 → 4p 2P1/2 transition...

SiC is a wide band gap semiconductor with an increasing number of applications in high-temperature electronics. Similar to Si, transition metals (TMs) in SiC are the source of deep levels in the band gap, however, the knowledge on structural properties of TMs in SiC, such as possible lattice sites, is much less advanced. In this work we report first results on the lattice site location of...

During LS1 an incremental upgrade of the REX-ISOLDE charge breeder along with its regular maintenance is foreseen. The goal is to increase the ion acceptance, pulse frequency and intensity by minor changes in the electron optics and operation settings.
In this contribution we present a complete simulation of the electron beam transport through the entire EBIS. Reliable results can be...

The ability of digital TDPAC spectrometers to process high count rates while providing flexible gating and evaluation options provides new opportunities for online measurements. In order to allow for online TDPAC measurements at ISOLDE, a specialized online TDPAC chamber will be build for the GLM branch.
We will present the concept of this chamber alongside first results of an online TDPAC...

The next generation of Rare Isotopes facilities, such as SPIRAL2, HIE-ISOLDE, FAIR, RIBF aims to push further the borders of our knowledge about fundamental properties of exotic nuclei. To do so, these facilities require a production of high quality beam that is adapted to the needs of various experiments.
Besides production mechanisms, mass separation techniques are crucial for the...

The mass is a unique property of an atomic nucleus, reflecting its binding energy and thus the sum of all interactions at work in the atom. Precise measurements of nuclear masses, especially of short-lived exotic nuclides with extreme proton-to-neutron imbalance, provide important input for nuclear structure and nuclear astrophysics investigations, for tests of the Standard Model, and for weak...

Rare Isotope Science Project (RISP) was launched by Institute for Basic Science (IBS) in December 2011 in Korea. We are developing Isotope Separation On-Line (ISOL) target system, which consists of 1.3 mm-thick uranium-carbide multi-disks and cylindrical tantalum heater, to provide various rare isotope beams for the researches in basic science and application. The intense neutron-rich nuclei...

One of the main goals of modern experimental nuclear physics is studying exotic nuclides far from the valley of stability of the nuclear chart. Measuring the mass of these nuclides allows gaining knowledge about the nuclear forces keeping nuclides bounded and about the resulting nuclear structure. ISOLTRAP is the Penning-trap mass spectrometer situated at ISOLDE-CERN used for high-precision...
