Time evolution of the PMT response for different PMT models at test bench In the test bench, the PMTs are excited using the laser light while a LED is used to generate charge to be integrated by the PMTs. The PMT response is normalized to the first day of data taking and to the signal of a reference PMT monitoring the light source intensity. Triangular points represent the PMT response of 3 PMTs model Hamamatsu R7877 dismounted from TileCal detector in February 2017. Once dismounted, these PMTs have integrated up to 40C in previous tests. Circular points and crosses represent the PMT response of 19 PMTs model Hamamatsu R11187, an evolution of model Hamamatsu R7877. This model is proposed for the PMT replacement for the HL-LHC. All the PMTs are equipped with high voltage active dividers to ensure the PMT linearity over a wide range of anode currents. There is a clear separation between the old and new PMT models. The new PMT model retains a good response in time under test and shows a smaller spread with respect to the old PMT model.

The experimental setup of the Pisa/INFN test bench for PMT qualification.
Main parts inside the optics box are: the laser head, a remote controlled filter wheel to change the transmitted beam intensity, two reference PMTs used to monitor the laser beam intensity, a beam expander, and a white fiber bundle to distribute the light to the tested PMTs. A green LED placed in front of the beam expander is used to flash higher intensity pulses for fast integration of large amounts of PMT anode charge.
PMTs under test are placed in a separated black box. Optical link between optics box and PMT box is done with white fibers. Temperature sensors are placed on the laser head and inside the PMT box.

The daily loop for PMT response measurement and large anode charge integration. Each daily measurements consists of 9 cycles. In each cycle : - 10k events with laser pulsing are acquired at maximum intensity; - 1k laser events are acquired with 6 different OD filters in the wheel for the intensity scan; - 10k events with LED pulsing are acquired; - The rest and major time of the cycle (about 2 house and 20 minutes), laser or LED pulsing for integrating anode charge without data storing.

PMT absolute gain measurements with the intensity scan method.

A linear fit is superimposed assuming the following simplified model: | |
Time stability of the PMT absolute gain.
PMT gain calculated with the intensity scan method (open circles)
and the covariance method (full circles). On day 20/01/2017 the PMT HV was increased from 700 V to 830 V. As expected, an increase of the gain by a factor about 2 is measured in all cases. The covariance method appears to be more precise, but a very good general agreement between the two methods is observed. No measurable gain drift is seen in the observation period of PMT excitation. Error bars include statistical and systematic (dominant) contributions.

PMT integrated anode charge. Integration of PMT anode charge is made at daily constant rate of about 0.5 C per day at about 5 uA average anode current. 30 C correspond approximately to half the total anode charge integrated during the entire LHC run II by the most exposed cells (A13) of the Tile Calorimeter.

Time evolution of the PMT response. Individual PMT response is normalized to the first day of observation and to the signal of a reference PMT monitoring the light source intensity. The reference PMT, model Hamamatsu R1636, not integrating sizable amounts of anode charge, was measured to be stable at 0.5% level. Each point is the average over 9 measurements taken each day. Error bars include statistical and systematic (dominant) contributions. Typical down-drift per integrated charge is about -0.1% / C. This value is consistent with the down-drift per integrated anode charge measured for PMTs mounted on detector Contacts: v.kazanine@mail.ru , sandra.leone@pi.infn.it , and fabrizio.scuri@pi.infn.it Reference: https://indico.cern.ch/event/2252701/ ![]() Date: February 21st, 2017 | ![]() [png] [eps] |
Time evolution of the PMT absolute gain. Individual absolute gain is computed with a statistical method based on the correlations between signals from PMT pairs (covariance method) and normalized to the first observation day. Gain of each individual PMT is the average of the values from all possible pairings with all other PMTs in the test sample (14). Individual PMT gain is averaged over 9 measurements taken each day. Error bars include statistical and systematic (dominant) contributions. Daily central values are stable whitin 1% along the observation period. By comparing the evolution of the PMT gain and the evolution of the PMT global response, it is possible to derive the loss in cathode Q.E.

Time evolution of the PMT response and PMT absolute gain at test bench. The PMT response and the PMT absolute gain are normalized to the first day of observation and to the signal of a reference PMT monitoring the light source intensity. Each point is the average over the response of 9 PMTs. Error bars include statistical and systematic (dominant) uncertainty. The average integrated charge in the observation period is 20 C so the typical down-drift per integrated charge is about -0.2% / C. The PMTs used were dismounted from TileCal detector in February 2017; they were reading out different cell type (A, BC, D, E) having integrated 1 to 5 C during run-I and run-II.

Estimation of the PMT response loss at HL-LHC era. Time evolution of the PMT response shows a fairly exponential decay shape both for measurements of on-detector sample and for test bench measurements. Assuming that the PMT response degrades exponentially and estimating the decay constant from the available measurement at the end of run I ad after 20 and 35 fb-1 in run II, it is possible to estimate PMT response loss. At the end of HL-LHC era, more exposed PMTs will have lost 50% of their response.

Spread of the PMT responses of A13 cell. Distribution of the A13 drift for a laser calibration run 311792 taken on 31 October 2016. The drift is evaluated with respect to the first laser calibration run after the last Cesium scan (25 May 2016). Only good PMT reading out are considered. The PMT under study have integrated 5 C in 2016. The RMS of the distribution is about 1.5 %, consistent with Hamamatsu specifics for same integrated anode charge. Laser accurancy is estimated to be 0,5 %.

TMDB block diagram. The TMDB is a 9U VME board, where the VME interface is handled by a dedicated FPGA (Cyclone III from Altera). Each board receives 32 channels from the 16 TileCal cells and performs the signal digitization using 8-bit flash ADCs. The digital signals from the 32 channels feed the core FPGA (Spartan-6 from Xilinx), where the energy estimation and signal detection is performed.

Figure shows the block diagram of the Module Processing Unit (MPU). The TMDB output corresponds to the energy value, in some arbitrary units, that is estimated by performing a inner product between the Matched Filter coefficients and the incoming time samples in ADC counts. The TMDB output is used to provide four TMDB decision triggers that are based on thresholds, two from the D6 cell and other two from D5+D6 cells.The trigger decision is obtained via AND logic between “Peak-detector" and “Thresholds" algorithms.

The analog pulses from the PMTs undergo conditioning and digitization in the first stage of the electronics, and transferred to the Daughter board at 40 MHz. The digital data are formatted and transmitted to the PreProcessor (PPr) modules through high speed fiber optic links. The PPr stores the digital data in pipelines and in parallel computes and transmits digital sums to the Trigger System through the Trigger and Data AcQuisition Interface (TDAQi) module. Upon the reception of the L0 accept signal, the digital signal are processed and transferred to the FELIX system. Contact: Alberto.Valero@cern.ch Date: 14th December 2022 |

The TileCal demonstrator hybrid read-out will combine a fully functional Phase-II read-out system with the analog trigger signals of the present system. The analog pulses from the PMTs undergo conditioning and amplification in the new version of the 3-in-1 card in two gains (high and low) with a ratio of 1:64. Low gain signals are summed in groups by adder cards and transmitted to the L1 Calorimeter system (dashed lines). The analog signals are digitized in the Main board at 40 MHz and transferred to the Daughter board which formats and transfers the data to the sROD through parallel fiber optic links using the GBT protocol. The sROD stores the digital data in pipelines and in parallel computes and transmits digital sums to the L1 Calorimeter System. Upon the reception of the L1 accept signal, the digital signal are processed and transferred to the Read-Out Buffer (ROB).
