| The dependence of the PMT anode current on track-counting Luminosity for a few channels of the Tile Calorimeter in fill 6364. Due to the placement of the different cells each one receives a distinct amount of signal explaining the range of slopes in the fit. The intercept at zero luminosity has nonzero values due to a small non-linear contribution to the anode current from the PMT HV divider.

| Fraction of the PMT anode current due to material activation for channel E3 EBA06 of the Tile Calorimeter extracted from a set of 2017 and 2018 LHC fills by measuring an increase in the PMT response (comparing the pedestal immediately before and immediately after the fill) normalised to the luminosity activity in the fill. Each fill has a different length and the fraction of signal from activation is plotted against the amount of time the fill was under collisions with error bars that represent the statistical errors. A fit using an activation function with a single time constant A (1-exp(-t/tau)) is shown and illustrates a short-term turn-on followed by a plateau that reflects the equilibrium between activation and decay.

Each fill has a different length and the fraction of signal from activation is plotted against the amount of time the fill was under collisions with error bars that represent the statistical errors. A fit using activation functions with two time constants A_1 (1-exp(-t/tau_1)) + A_2 (1-exp(-t/tau_2)) is shown and illustrates a short-term turn-on followed by a slower rise suggestive of the presence of an isotope with a longer half-life.

| Fraction of the PMT anode current due to material activation in different channels of the Tile Calorimeter computed on a dataset of runs from 2017 and 2018 by measuring an increase in the PMT response (comparing the pedestal immediately before and immediately after the fill) normalised to the luminosity activity in the fill. Each fill has a different length and the fraction of signal from activation is plotted against the amount of time the fill was under collisions with error bars that represent the statistical errors. Fits using activation functions with a single time constant A (1-exp(-t/tau)) are shown and illustrate short-term turn-ons and the equilibrium plateaux. The activation build-ups reflect on the contribution to activation from different materials, depending on the cell positioning inside the ATLAS detector. In some cases (E3 and E4) a single exponential is sufficient to approximate the activation, while in other cases (A12L) two exponentials are required. The plateau for E3 is higher due to its larger active volume compared to the E4 cells.

| Ratios of the instantaneous luminosity measured by TILE E-cell scintillator families of EBA and EBC to that from track-counting in fill 6847 and closely following physics fills. The plots focus on different periods of time with changing beam properties such as the number of bunches or the luminosity scale which affect the agreement between TILE and track-counting measurements and can provide a measure of the uncertainty of the ATLAS calibration transfer procedure. Effects from activation decay can be seen in the negative slope for the low mu part of fill 6847 while signs of activation build up is visible in the positive slopes at the beginning of the three middle plots. The fill that corresponds to one of the head-on periods of the vdM run taken a few days later is also shown. Ratios using TILE E cells are averaged over 1-minute intervals and with the integrated ratio normalised to unity during fill 6850, in the range indicated by the green box.

| Deviation of the instantaneous luminosity measured by Tile D-cell scintillator families of EBA and EBC to that from track-counting during 2018. The luminosity measurements by Tile are normalised to track-counting in the fill indicated by the arrow. No significant deviation beyond half a percent is observed making the D-cell families the most stable since they are the most isolated cells in the Tile Calorimeter and are hence less affected by ageing. Laser corrections for the PMT ageing are included and the progressively more negative deviations are attributed to scintillator ageing.

| During the LHC collisions a dedicated TileCal readout provides measurement of the anode current for every photomultplier. An average anode current for A13 cell of the TileCal is shown as a functon of the instant luminosity on full data sample taken in 2010. The errors on the current are the quadratc sum of the statstcal and systematc errors. The red lines are obtained from the linear ft of the data points.

The module number is shown on the X-axis, while the Y-axis shows the relatve anode current. The error bars represent the run to run variaton of the measurement (RMS), also shown separately on the botom plot. This variaton is typical about 0.5% refectng the stability of the system. The standard deviaton module to module is about 1.5%, and the dashed lines represent a ±2.5% band enclosing 90% of the measurements.

| Luminosity coefficient (PMT anode current over instantaneous luminosity) vs η measured by Minimum Bias system in proton-proton collision data collected during run 348610 of the 2018 data period. A range of 20 consecutive lumiblocks (time interval) has been used. The average of the corresponding instantaneous luminosity is 1.7 x 1033 cm-2 s-1. Each cell of the Tile Calorimeter covers a range in η. The cells are distributed over 64 modules in phi and read out by one or two PMTs. The average currents for all channels belonging to a cell have been used to calculate the luminosity coefficient by dividing by the corresponding average inst. luminosity. The error bars represent the standard deviation of currents/ average inst. luminosity measured for a given cell. Different sets of gains are used in the cells in the gap/ crack region (E-cells) to measure the higher currents. Compared to previous years, the coefficients for E3 and E4 cells (1.2<|η|<1.6) have changed given a decrease in operating HV used in the counters.
