“…The incident light intensity on the photocathode is tuned by changing the amplitude of the supply voltage to the LED. Less than 10% effective triggering rate is tuned to ensure that the acquired charge distribution is a SPE spectrum [7]. Each waveform of the PMTs has been recorded and been analyzed by off-line processing which includes peak searching and baseline calculation.…”

Photomultiplier tube (PMT) has been an essential instrument for low background experiments, and the accuracy of single photoelectron (SPE) calibration will directly affect the energy reconstruction of the detector. The SPE spectrum can be acquired from the charge distribution of dark-noise pulses or the low-intensity light signal triggered by LED. However, there are arguments on whether the two methods are consistent. In this paper, the Hamamatsu R5912-20mod PMT and the EMI-D642KNFL PMT have been tested adopting the two methods with signal waveform recording electronics. As comparison, traditional charge-to-digital conversion system is also used to test SPE spectrum. The results show that they are consistent when the PMTs are working at typical recommended high voltage (HV).

“…The signal from PMT was read out by charge-sensitive ADC LeCroy 2249W with 250f C/channel sensitivity using a 160ns gate triggered by two scintillator counters. Calibration of PMT was done by fitting the single photoelectron distribution, produced by 15ns light pulses of blue LED [5]. The average number of photoelectrons induced by cosmic muons are presented in Table 1.…”

The application of reach-through avalanche photodiodes (R'APD) as a photodetector for scintillator tiles has been investigated. The light collected by WLS fibers (0.84mm and 1mm diameter) embedded in the scintillator has been transmited to the 0.5mm 2 active surface of APD by clear optical fibers and optical connectors. A low noise charge sensitive preamplifier (≈ 400e − equivalent noise charge) has been used to gain the photodiode signal. Various configurations of tile-fibre systems, suitable for CMS and LHCb experiments at LHC have been studied using cosmic muons and muon beam at SPS at CERN. In order to optimize the performance of APD, measurments in the temperature range from −10 o C to +25 o C have been done. The M IP detection efficiency and e − /M IP separation have been estimated in order to determine applicability of the readout for LHCb preshower.

“…Moreover, the n th photoelectron peak is given by Q n = Q 0 +nQ 1 and the variance is σ Fitting Eq. 2.3 with parameters Q n , σ n , w, µ and α as fit parameters to ADC data collected in the manner previously discussed, allowed the gain of the Photonis XP2262 PMT to be determined and is given by the parameter Q 1 [18]. It is useful to note that up to fifteen photoelectron peaks were used to fit the SPE ADC data when only four fits were drawn in Fig.…”

“…Assuming the background events contributing to the total charge collected by the PMT is given by a convolution of a Gaussian and an exponential discussed in [18], then the realistic PMT signal response distribution is given by the convolution seen in Eq.…”
