Introduction

This page lists the public plots produced within the Tile Calorimeter calibration group. The results obtained using the Charge Injection System are presented. All the plots are taken from https://twiki.cern.ch/twiki/bin/view/AtlasPublic/ApprovedPlotsTileCalibration#Charge_injection_system_CIS

Approved Tile Calorimeter Charge Injection System (CIS) Calibration Plots


2018 Data
These three plots show the Charge Injection System (CIS) calibration constants (ADC counts / pC) for all the high gain (HG) and low gain (LG) channels in the ATLAS Tile Calorimeter LBA modules for a single run 367000 taken in November 2018. They have been created by 'PlotCalibFromCool.py' script reading CIS constants back from 'TileOfl02CalibCisLin-RUN2-UPD14-18' tag of COOLOFL_TILE Database. The third plot shows the same LG CIS constants as the second plot, but with the modified scale of Z-axis for CIS constant value.

2018 Data
These histograms show the distribution of the Charge Injection System (CIS) calibration constants for a single run taken on 4th November 2018 for all the low-gain (LG) and high-gain (HG) channels in the entire detector. Typical variation is approximately 1.6% for such channels. In addition, the systematic uncertainty is 0.7% for the calibration constants of individuals channels.

We expect this to be narrow. It shows that the constants are stable. Because of selection of only good channels with stable CIS constants, the number of entries does not equal 9852, the number of connected high-gain channels.

Run 2 Data
Detector-wide CIS calibration constant averages of all the high-gain (above) and low-gain (below) ADCs for a selection of CIS calibration runs spanning Run 2, plotted as black circles. The CIS constants from a typical channel (LBC20, Channel 35 for HG; LBC20, Channel 33 for LG) are additionally plotted as blue triangles for comparison. The RMS values on the plots are indicative of the fluctuation present in calibrations. In addition, there is a 0.7% systematic uncertainty present in individual calibrations, represented by the yellow error band. This uncertainty comes from the observed peak output amplitudes and is taken as characteristic of the channel-to-channel variation from this source, prior to any calibration. Problematic channels are not included when calculating the mean.

2014 Data
This 1D graph shows the detector-wide CIS calibration constants averages of all the high gain channels (first plot) and all the low gain channels (second plot) from 15 Feb’13 to 14 Sep’14. Note that only “good” channels with stable constants are being considered. A typical channel (LBC19, Channel 13) is plotted alongside for comparison. This channel was powered off from 20 Jan’14 to 10 Feb’14 in which there were 15 runs executed. Hence, one can note some missing “blue triangles” during that time period. The dates where there are no blue or black points imply that there were no CIS runs performed.

The ratio of CIS constant RMS to mean for all channels, both high-gain (HG) and low-gain (LG), in the detector for the time period between August 2015-November 2018, spanning all of Run 2. Overflow is included in the rightmost bin of both histograms. Channels that are unresponsive or show certain TUCS quality flags are not included.

Winter 2017 Data
This histogram shows the ratio of CIS constant RMS to mean for all channels in the detector for the time period between 15 May 2017 and 05 December 2017. Unstable channels are typically considered to have a RMS/mean above 0.38% as indicated by the blue line. Channels that are unresponsive or fail certain TUCS quality flags are not included.
