/IS634 Collaboration
The lattice location of ion implanted radioactive 24Na (t1/2=14.96 h) in GaN and AlN was determined using the emission channeling technique at the ISOLDE/CERN facility. In the room temperature as-implanted state in both GaN and AlN, the majority of the sodium atoms are found on interstitial sites near the octahedral position, with a minority on cation Ga or Al substitutional sites.

Versatile firmware for the Common Readout Unit (CRU) of the LHC ALICE experiment
/ Bourrion, O. (LPSC, Grenoble) ; Bouvier, J. (LPSC, Grenoble) ; Costa, F. (CERN) ; David, E. (Wigner RCP, Budapest) ; Imrek, J. (Wigner RCP, Budapest) ; Nguyen, T.M. (Wigner RCP, Budapest) ; Mukherjee, S. (Bose Inst., Kolkata)
As from the run 3 of CERN LHC scheduled in 2022, the upgraded ALICE experiment will use a Common Readout Unit (CRU) at the heart of the data acquisition system. The CRU, based on the PCIe40 hardware designed for LHCb, is a common interface between 3 main sub-systems: the front-end, the computing system, and the trigger and timing system. [...]

Lattice location study of low-fluence ion-implanted 124In in 3C-SiC
/ Costa, A. R. G. ; Wahl, U. ; Correia, J. G. ; David-Bosne, E. ; Augustyns, V. ; Lima, T. A. L. ; Silva, D. J. ; da Silva, M. R. ; Bharuth-Ram, K. ; Pereira, L. M. C.
We report on the lattice location of low-fluence ion implanted 124In in single-crystalline 3C-SiC by means of the emission channeling technique using radioactive isotopes produced at the ISOLDE/CERN facility. In the sample implanted at room temperature to a fluence of 4 × 1012 cm−2, 60(9)% of the In atoms were found slightly displaced (0.12–0.20 Å) from substitutional Si sites, with the remainder occupying sites of low crystallographic symmetry, the so-called random sites.

/ISOLDE
Using radioactive isotopes produced at the CERN-ISOLDE facility, the lattice location of the implanted transition metal (TM) ions $^56$Mn, $^59$Fe and $^65$Ni in n-type single-crystalline hexagonal 6H-SiC was studied by means of the emission channeling technique. TM probes on carbon coordinated tetrahedral interstitial sites ($T_C$) and on substitutional silicon sites ($S_{Si,h+k}$) were identified. [...]

Trigger and Timing Distributions using the TTC-PON and GBT Bridge Connection in ALICE for the LHC Run 3 Upgrade
/ Mitra, Jubin (Calcutta, VECC) ; David, Erno (Wigner RCP, Budapest) ; Mendez, Eduardo (CERN) ; Khan, Shuaib Ahmad (Calcutta, VECC) ; Kiss, Tivadar (Wigner RCP, Budapest) ; Baron, Sophie (CERN) ; Kluge, Alex (CERN) ; Nayak, Tapan (Calcutta, VECC)
The ALICE experiment at CERN is preparing for a major upgrade for the third phase of data taking run (Run 3), when the high luminosity phase of the Large Hadron Collider (LHC) starts. The increase in the beam luminosity will result in high interaction rate causing the data acquisition rate to exceed 3 TB/sec. [...]

A potent approach for the development of FPGA based DAQ system for HEP experiments
/ Khan, Shuaib Ahmad (Calcutta, VECC) ; Mitra, Jubin (Calcutta, VECC) ; David, Erno (Wigner RCP, Budapest) ; Kiss, Tivadar (Wigner RCP, Budapest) ; Nayak, Tapan Kumar (Calcutta, VECC ; CERN)
With ever increasing particle beam energies and interaction rates in modern High Energy Physics (HEP) experiments in the present and future accelerator facilities, there has always been the demand for robust Data Acquisition (DAQ) schemes which perform in the harsh radiation environment and handle high data volume. The scheme is required to be flexible enough to adapt to the demands of future detector and electronics upgrades, and at the same time keeping the cost factor in mind. [...]

The solid state physics programme at ISOLDE: recent developments and perspectives
/ Johnston, Karl (CERN) ; Schell, Juliana (CERN ; Duisburg-Essen U.) ; Correia, J G (CERN ; IST/ITN, Lisbon) ; Deicher, M (Hamburg U.) ; Gunnlaugsson, H P (Iceland U.) ; Fenta, A S (CERN ; Aveiro U. ; Leuven U.) ; David-Bosne, E (CERN ; IST/ITN, Lisbon) ; Costa, A R G (CERN ; IST/ITN, Lisbon) ; Lupascu, Doru C (Duisburg-Essen U.)
Solid state physics (SSP) research at ISOLDE has been running since the mid-1970s and accounts for about 10%–15% of the overall physics programme. ISOLDE is the world flagship for the on-line production of exotic radioactive isotopes, with high yields, high elemental selectivity and isotopic purity. [...]
