“…The standard deviation of the relative gains among the 64 pixels was found to be 7.9% with respect to the average one, and the smallest output was 75% of the largest. This uniformity is better than that of 30% as reported for a multi-anode PMT commercially available in the market [15].…”

A multi-pixel photon sensor with single-photon sensitivity has been developed. Based on a hybrid photo-detector (HPD) technology, it consists of a photocathode and a multi-pixel avalanche diode (MP-AD). The developed HPD has a proximity-focused structure, where the photocathode and MP-AD face each other with a small gap of 2.5 mm. The MP-AD, which has an effective area of 16mm×16mm, is composed of 8×8 pixel and has been specially designed for the HPD. The maximum gain of the HPD is 5×10 4 , sufficiently high to detect single photons with a timing resolution better than 100 ps. Up to four photoelectrons can be clearly identified as distinct peaks in a pulse-height spectrum, thanks to the low noise characteristics of the HPD. It is also 1 demonstrated that the HPD can be operated with good performance in a magnetic field as high as 1.5T.

“…The standard deviation among them is 6.0%, when it is normalized to the average output signal. This uniformity is better than the value of 30% reported for a multi-anode PMT commercially available [3]. Sources of this non-uniformity are attributed to the photocathode sensitivity, the electron bombarded gain and the avalanche gains as reported in [6], [7].…”

“…M ULTI-PIXEL photon sensors with single-photon sensitivity are widely used in high-energy physics detectors, such as scintillating fibers [1] or Cherenkov counter readout [2], [3]. Broader applications are expected if the sensors can operate in a strong magnetic field [4], [5].…”

Abstract-A hybrid photo-detector (HPD) consisting of a photocathode and a multi-pixel avalanche diode (MP-AD) was developed a few years ago. Our previous studies showed that its inherent potential for high resolution photon counting could be further enhanced by reducing fluctuations in charge loss in the dead layer at the entrance of the MP-AD. In this paper, we report on the improvement with the newly developed HPD whose encapsulated MP-AD has a thinner dead layer than before. It is demonstrated that the new HPD has much better energy resolution, which enables clearer counting up to nine photoelectrons. Further enhancement of the photocathode sensitivity of the HPD is also discussed.

The 64-channel Multianode Photo Multiplier (MaPMT) has been evaluated as a candidate for the LHCb Ring Imaging Cherenkov (RICH) photo detectors. We present result from data taken with a 3x3 array of closely packed MaPMTs mounted onto the RICH 1 prototype vessel, exposed to charged particle beams at CERN, and read out at LHC speed. Using a LED light source, we have performed spatial light scans to study the light collection efficiency of the MaPMTs We have also measured the performance of the MaPMTs as a function of the applied high voltage. Different dynode resistor chains have been used to study the tubes at low gains. In addition, we have studied the behaviour of the MaPMT in magnetic fields.
