This page lists the public plots illustrating status of the detector.

Detector Status

"Evolution of Cell Masking in TileCalorimeter".This plot shows the percentage of all cells and channels in the detector that are masked as a function of time starting from December 2010. The recent detector status corresponding to the 03 December, 2018 is noted. The hatched area represents the maintenance period of the detector. The legend includes the amount of masked cells (0.48%) and masked channels (1.07%) at that time. The total number of cells, including gap, crack, and minimum bias trigger scintillators, is 5198.

"Eta-­Phi representation of the Number of Tile Masked Cells". This plot shows the number of cells masked in each eta-­phi bin. The bin is chosen to be 0.1 x 0.1, corresponding to the calorimeter tower definition. Cells in Tile Calorimeter can have one or two readout channels.The analog signal from each channel is then amplified in separate high (HG) and low (LG) branches and digitized by two ADCs. The bin color corresponding to integer numbers is the integrated number of cells in calorimeter tower. The non-integer numbers mean the integrated fraction of masked ADCs in tower.

Time evolution of the events with digital errors in a DMU in the Tile Calorimeter in a subsample of the physics data used for monitoring purposes. Modules that are powered off are reported as having digital errors. Red squares represent the integrated luminosity for each run. The maintenance period at the end of 2011 can be seen, as well as the decrease in the quantity of digital errors after this period, basically due to the decreased number of unpowered modules.
Last Update (October 23, 2012):

The total online luminosity lost from Tile DQ problems is 104 \ipb. The primary source of Tile luminosity losses is from the stop-less Read-Out Link (ROL) removal in the extended barrels accounting for 76.5 \ipb, of this 31.3 \ipb came with a -25 ns timing shift in EBC. Power cuts or trips of the 200V power supplies counted for 22.6 \ipb. The last 4.9 \ipb of loss came from Laser Calibration ROD (LASTROD) busy. Each bin in the plot contains about two weeks.
