Phys.) ; Kaplon, J (CERN) ; Keener, P (Pennsylvania U.) ; Narayan, A (Pennsylvania U.) ; Newcomer, M (Pennsylvania U.) ; Swientek, K (AGH-UST, Cracow)
/ATLAS ITk Strips
The ATLAS experiment will build an all-silicon tracker in the Phase II upgrade for the High Luminosity LHC (HL-LHC) at CERN. For the silicon strip detector of the Inner Tracker, a new readout chip ABCStar is under design to cope with the increased occupancies and harsher radiation environment, and to accomodate the new trigger architecture.

On the creation of the 17 MeV X boson in the 17.6 MeV M1 transition of $^8Be$
/ Krasznahorkay, A J (Debrecen, Inst. Nucl. Res.) ; Csatlós, M (Debrecen, Inst. Nucl. Res.) ; Csige, L (Debrecen, Inst. Nucl. Res.) ; Gulyás, J (Debrecen, Inst. Nucl. Res.) ; Ketel, T J (NIKHEF, Amsterdam) ; Krasznahorkay, A (CERN ; MIT) ; Kuti, I (Debrecen, Inst. Nucl. Res.) ; Nagy, Á (Debrecen, Inst. Nucl. Res.) ; Nyakó, B M (Debrecen, Inst. Nucl. Res.) ; Sas, N (Debrecen, Inst. Nucl. Res.) et al.
Electron-positron angular correlations were remeasured for the 17.6 MeV $(J^π = 1^+ \to 0^+)$ ground state transition in $^8Be$ using an improved setup compared to one we used previously. Significant deviations from the internal pair creation was observed at large angles in the angular correlations, which supports that, in an intermediate step, a neutral isoscalar particle with a mass of 17.0±0.5 (stat)±0.5 (sys) $MeV/c^2$ and $J^π = 1^+$ was created..

Design of a radiation tolerant system for total ionizing dose monitoring using floating gate and RadFET dosimeters
/ Ferraro, R (CERN ; LIRMM, Montpellier) ; Danzeca, S (CERN) ; Brucoli, M (CERN ; IES, Montpellier) ; Masi, A (CERN) ; Brugger, M (CERN) ; Dilillo, L (LIRMM, Montpellier ; CNRS, France)
The need for upgrading the Total Ionizing Dose (TID) measurement resolution of the current version of the Radiation Monitoring system for the LHC complex has driven the research of new TID sensors. The sensors being developed nowadays can be defined as Systems On Chip (SOC) with both analog and digital circuitries embedded in the same silicon. [...]

Antimatter Gravity Measurements with Cold Antihydrogen: the AEgIS Experiment
/ Doser, M (CERN ; Moscow, ITEP)
/AEgIS
The AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) experiment has the objective of testing the weak equivalence principle for antimatter, by studying the free fall of antihydrogen atoms in the Earth’s gravitational field, as well as carrying out a measurement of the hyperfine splitting of their ground state. A pulsed cold beam of antihydrogen produced by charge exchange between cold positronium (laser excited into a Rydberg state with principal quantum number n ∼ 25-35) and cold antiprotons will be transformed into a horizontal beam through Stark acceleration, whose free fall will be measured by a classical moirée deflectometer.

Commissioning of ATLAS and early measurements with leptons in ATLAS and CMS
/ Plamondon, M (Orsay, LAL)
/ATLAS ; CMS
With only a few months until the LHC start-up, the commissioning of ATLAS is in its final stage as the last components of the detector are installed. The understanding of the detector response acquired during the preparation phase is presented as well as the expected performance at start-up. [...]
