247. #01-247 ATLAS LAr Calorimeter Commissioning for LHC Run-3

ELLIS, Kay (CERN, Switzerland)

6/22/21, 2:00 PM

01 Fundamental Physics

Oral presentation

Liquid argon (LAr) sampling calorimeters are employed by ATLAS for all electromagnetic
calorimetry in the pseudo-rapidity region |η| < 3.2, and for hadronic and forward
calorimetry in the region from |η| = 1.5 to |η| = 4.9. In the first LHC run a total luminosity of
27 fb${}^{-1}$ has been collected at center-of-mass energies of 7-8 TeV. After detector consolidation
during a long shutdown,...

228. #01-228 A high speed data link optimization for digitalized data transfer to processing FPGAs

COLLADO, Javier (Instituto de Física Corpuscular (IFIC) - CSIC / Universidad de Valencia - ETSE)

6/22/21, 2:20 PM

01 Fundamental Physics

Oral presentation

State-of-the-art arrays of detectors, that require digital processing, may have a sizeable number of digitalized signal links. This is the case in several experimental nuclear physics instruments. Moreover, the sampled signals data rate, defined primary by the signal bandwidth of the individual detector, may not exhaust the capabilities of a single FPGA transceiver input.
This is a critical...

6/22/21, 2:40 PM

01 Fundamental Physics

Oral presentation

he Tile Calorimeter (TileCal) is the central hadronic calorimeter of the ATLAS detector at the Large Hadron Collider (LHC). This subdetector is a sampling calorimeter composed of steel plates as absorber material and plastic scintillators as active material. The complete readout of the detector is done using approximately 10,000 photomultipliers (PMTs).
The LHC will undergo a series of...

191. #01-191 Preliminary results of the CGEM-IT of the BESIII experiment

6/22/21, 3:00 PM

01 Fundamental Physics

Oral presentation

The BESIII (Beijing Spectrometer III) experiment is hosted at the leptonic collider BEPCII (Beijing Electron Positron Collider II) at IHEP in Beijing and it is successfully running since 2009. Recently, an extension of the data taking for the next 10 years has been approved, so an upgrade program has started. A central element of the upgrade is the replacement of the present inner tracker with...

84. #01-84 Measurement of anomalies in angular correlation of electron and positron internally produced in excited 8Be and 4He

PETOUSIS, Vlasios (IEAP - CTU)

6/22/21, 3:20 PM

01 Fundamental Physics

Oral presentation

Theoretical prediction for the distribution of the angle between electrons and positrons originating in internal pair creations is a monotonic featureless decrease with the opening angle. Recent studies on excited states of 8Be and 4He nuclei, made in ATOMKI, Hungary, however, revealed deviations from this expectation. If true, such a result may have a fundamental impact: the anomaly can be...

248. #01-248 Development of the ATLAS Liquid Argon Calorimeter Readout Electronics for the HL-LHC

6/23/21, 4:20 PM

01 Fundamental Physics

Poster

To meet new TDAQ buffering requirements and withstand the high expected radiation doses
at the high-luminosity LHC, the ATLAS Liquid Argon Calorimeter readout electronics will be
upgraded. The triangular calorimeter signals are amplified and shaped by analogue
electronics over a dynamic range of 16 bits, with low noise and excellent linearity.
Developments of low-power preamplifiers and...

215. #01-215 Experiments with fast neutrons at nELBE

6/23/21, 4:25 PM

01 Fundamental Physics

Poster

The neutron time-of-flight facility nELBE at Helmholtz-Zentrum Dresden-Rossendorf features the first photo-neutron source at a superconducting electron accelerator. The electrons are focused onto a liquid lead target to produce bremsstrahlung which in turn produces neutrons via photo-nuclear reactions. The emitted neutron spectrum ranges from about 10 keV up to 15 MeV with a source strength of...

6/23/21, 4:35 PM

01 Fundamental Physics

Poster

The natural niobium metal is well suited for atomic reactors due to its high temperature resistant, corrosion resistant, low long term induced radioactivity properties. Niobium alloys such as NbTi and Nb3Sn are used as super magnets in fusion reactors due to its super conducting properties. The 93Nb(n,2n)92mNb reaction is also used as monitor reaction. Therefore accurate data of...
