Introduction

This page shows public results from the Radiation Simulation Working Group.
The FLUKA simulations have focused more on the needs of the ID/ITK communities, and FLUGG for the muon systems. The GCALOR and GEANT4 studies have focused more on radiation background issues in the calorimeter systems.

Comparisons between measurement and simulation:

IBL Run 2 (April 2018)

Fluence-per-luminosity conversion factors extracted from leakage current fits as a function of distance along the IBL stave, compared with Pythia 8 + FLUKA 2011 and Pythia 8 + Geant 4 [0,1].  The Hamburg model [2] is used to fit the leakage current data, with the Fluence-per-luminosity conversion factor as one of the fit parameters:

Ileak = (Φ / Lint) x V x Σi=1n Lint,i x [α Iexp(-Σj=in tj/τ(Tj)) + α0* - βlog(Σj=in Θ(Tj) x tj / t0)]

where V is the sensor volume, Φ is the fluence, Lint is the integrated luminosity, t is time, T is temperature and the sum is over all time periods i. The values for the various parameters can be found in [2] and Φ/Lint is fit to the data. The error bars from the leakage current extraction are dominated by a conservative 10% uncertainty, accounting for the variation in the bias voltage at full depletion. Uncertainties due to the annealing model (0.1%) and data fit (0.5%) are subdominant.  Note that the uncertainty in the parameters of the Hamburg annealing model are about 5% [2], but the quoted uncertainty is the impact of those uncertainties on the extracted value of Φ/Lint.

The Pythia 8 simulation uses the MSTW2008LO PDF with either the A2 [3] or A3 [4] minimum bias tunes. A description of the ATLAS FLUKA simulation framework can be found in [5]. The ATLAS detector geometry models are not identical between Geant 4 and FLUKA - the former uses the full geometry model employed by the standard ATLAS Monte Carlo production system [1] while the latter uses a simplified standalone geometry. The predictions are mirrored for +/- |z|, so there is symmetry by construction. Only Monte Carlo statistical uncertainties are shown for the simulation predictions. Due to the more complex geometry used by Geant 4, the statistical uncertainties are enhanced (from the tilt of the IBL staves in φ); the FLUKA simulation also uses a factor of 5 more events than the Geant4 prediction.

Inner Detector Radmons (April 2018)

FLUKA Simulations:

Phase II ITk Inclined Duals (April 2018)

These plots shows the results of FLUKA [1] simulations of radiation fluence and dose in the ATLAS Phase-2 Upgrade Inner Tracker (ITk) regions. The ITk layout simulated is the inclined duals layout as described in the Pixel TDR [2]. The minimum-bias pp collisions are simulated with ATLAS-tuned Pythia8 [3] at 14 TeV centre of mass energy and predicted inelastic cross section of 79.3 mb. The tune used is the A2 tune [4]. The radiation environment is characterized by three quantities:
1) 1 MeV equivalent neutron fluence, i.e., the fluence of 1 MeV neutrons that would cause the same amount of displacement damage in silicon as the actual mixed particle spectrum. To obtain this quantity each fluence component is weighted by a particle- and energy-dependent damage factor which expresses the damage relative to 1 MeV neutrons. For the latter the Non Ionising Energy Loss (NIEL) in silicon is defined as 95 MeV mb.
2) Total Ionising Dose (TID), defined as the energy deposited by ionisation divided by the mass of the material where the energy is deposited.
3) Fluence of hadrons with E > 20 MeV, which can be used to estimate the rate of Single Event Effects (SEE) in electronics components by comparing with the SEE rate of a given device in a beam test.

Phase II Upgrade (Mar 2018)

These plots show the results of FLUKA simulations of the 1 MeV neutron equivalent damage in silicon for the ITk region of the ATLAS Phase II upgrade.
The purpose of this set of plots is to illustrate that in inner regions of the ITk, notably in the Pixel detector, the silicon bulk damage is not dominated by neutrons but by other particles. These are mostly pions and other charged hadrons, with minor contribution from neutral hadrons, electrons, positrons, muons and photons.
All particle fluences have been weighted with the corresponding particle- and energy-dependent hardness factors in silicon. The fluences are expressed in terms of silicon 1 MeV equivalent fluence, i.e. the fluence of mono-energetic 1 MeV neutrons (defined to have a non-ionising energy loss (NIEL) of 95 MeV mb) that would cause the same amount of NIEL in silicon as the actual radiation field. Where relevant, the plots are normalised to an integrated luminosity of 4000 fb−1 of pp collisions. The pp collisions are simulated with Pythia8 minimum bias events at 14 TeV centre of mass energy, with an assumed inelastic cross section of 80 mb. The radiation levels are assumed to be symmetric in azimuth and about z = 0.

HGTD results (Oct 2016)

Si1MeVneq fluence in the hottest spot of the outermost ITk Strip disk relative to the baseline without a HGTD. The values correspond to the hottest spot at the lowest edge of the out- ermost disk, defined as an annular ring between r = 38–44 cm and z = 296–300 cm. The horizontal line, showing the baseline configuration with 50mm moderator and no HGTD, is considered the target level for the shielding optimisation. The solid blue circles and the fit show the reduction as a function of the moderator thickness between the ITk and the HGTD. The slope of the fit is 0.285cm−1, which implies that 50mm of moderator should reduce the Si1MeVneq fluence by a factor of 4.2. The significant constant term, due to high energy hadrons, causes the real effect to be only a factor 1.4. The other symbols at 50 mm thickness correspond to configurations in which the HGTD is on the ITk side of the moderator. They differ only in terms of moderator thickness at r > 70 cm.

Neutron spectra averaged over the fourth silicon layer of the HGTD from r = 110mm to r = 700 mm. The plain HGTD is not protected by a moderator while the optimised moderator layout includes a 50 mm BPE layer at r < 90 cm, continued with a 20 mm thick layer to the outer radius of the endcap. The spiky stuctures between 1 keV and 10 MeV are due to resonances. The uncertainties are of the order of 5 %.

HGTD results for the ECFA Upgrade workshop 2016

Ionising dose in the readout chips of the HGTD layer closest to the ATLAS endcap calorimeter. The histograms represent the three different HGTD layouts that have been studied: the preshower option (black circles), with 3.5 mm thick borated polyethylene moderator layers from R=47 mm to R=284 mm, continued with tungsten plates of the same thickness from R=284 mm to R=700 mm, an option with the tungsten replaced by borated polyethylene (red triangles), giving a total of 10 mm moderator over the full radial range of the HGTD and an option with no moderator inside the detector (blue squares). While the presence of the tungsten plates increases the dose significantly in the radial range covered by these plates, the borated polyethylene has no influence on the ionising dose. The Z position of the HGTD as described in the FLUKA geometry is: Z=±[3461,3516] mm.

Comparison of the non-ionising energy loss (NIEL) in the ITk region close to the endcap for three alternative HGTD layouts with respect to the baseline configuration without the HGTD, but 5 cm of borated polyethylene all over the calorimeter endcap face. The histograms represent the preshower option (black circles), with 3.5 mm thick borated polyethylene moderator layers from R=47mm to R=284mm, continued with tungsten plates of the same thickness from R=284 mm to R=700 mm, an option with the tungsten replaced by borated polyethylene (red triangles), giving a total of 10 mm moderator over the full radial range of the HGTD and an option with no moderator inside the detector (blue squares). From R=700 mm to R=800 mm a gap for service routing is left. In the simulations this region contains only air – the presence of cables is likely to reduce the fluence to some extent. The fourth histogram (green open squares) shows the baseline case with 5 cm moderator and no HGTD. Depending on the layout the NIEL in the ITk volume just next to the endcap increases, with respect to the baseline, by 40–140% in the radial range covered by the HGTD. The Z position of the HGTD as described in the FLUKA geometry is: Z=±[3461,3516] mm.

Athena G4 Simulations

Run 2 Tile Calorimeter studies (May 2018)

Total ionisation doses from GEANT4 simulations of the ATLAS detector in the Tile calorimeter (see ATLAS Collaboration, “Mechanical construction and installation of the ATLAS tile calorimeter”, JINST 8, T11001 (2013)) region are presented for proton- proton collisions at a centre-of-mass energy of √s = 13 TeV for a) scintillating tiles, b) steel absorbers and c) all materials as average dose from the sum of individual doses. Scintillators and steel absorbers account for about 93% of the total volume of the Tile calorimeter. The remaining 7% are filled mostly with air and to a minor fraction with glue. The simulation is based on 50000 inelastic proton-proton events generated with PYTHIA 8 using the A3 tune (see ATLAS Collaboration, “A study of the Pythia 8 description of ATLAS minimum bias measurements with the Donnachie-Landshoff diffractive model”, ATL-PHYS-PUB- 2016-017 (2016), https://cds.cern.ch/record/2206965) and the NNPDF23LO PDF at a centre-of-mass energy of 13 TeV normalised to a cross section of σinel = 78.42 mb and an integrated luminosity of L = 1 fb−1.

Phase II Upgrade (Mar 2018)

Average material density from GEANT4 simulations of the ATLAS detector in a configuration for the Phase-II upgrade of the LHC. The values are calculated from the ratio of the total deposited ionisation energy density in a given r − |z|-bin (∆r × ∆|z| = 4 × 4 cm2) and the total ionisation dose in the same bin. They are reflecting the actual density in homogenous regions and a bin-average in volumes with material mixes. The simulation is based on 49150 inelastic proton-proton events generated with PYTHIA 8 using the A2 tune (see ATLAS-PHYS-PUB-2012-003) and the MSTW2008LO PDF at a centre-of-mass energy of 14 TeV.
