“…Silicon Photomultipliers (SiPM) are novel photon detectors whose potential is presently studied by many groups concerning their applicability in many different fields such as high energy physics calorimetry, astrophysics or medical imaging [1][2][3]. SiPMs consist of a matrix of typically 1000 independent micro-cells (pixels) per mm 2 which are connected in parallel.…”

This paper describes an experimental setup that has been developed to measure and characterise properties of Silicon Photomultipliers (SiPM). The measured SiPM properties are of general interest for a multitude of potential applications and comprise the Photon Detection Efficiency (PDE), the voltage dependent cross-talk and the after-pulse probabilities. With the described setup the absolute PDE can be determined as a function of wavelength covering a spectral range from 350 to 1000 nm. In addition, a method is presented which allows to study the pixel uniformity in terms of the spatial variations of sensitivity and gain. The results from various commercially available SiPMs -three HAMAMATSU MPPCs and one SensL SPM -are presented and compared.

Geiger avalanche photodiodes as tentative light detectors for VHE gamma ray astronomy

et al. 2009

International audienceDue to its sensitivity and speed, the detector still widely used in Cerenkov astrophysics experiments remains the PhotoMultiplier Tube (PMT). For instance, recent pathbreaking experiments in Very High Energy astrophysics (VHE), such as MAGIC and HESS, have used mainstream PMT technology (Aharonian et al, Astron Astrophys 492(1):L25-L28, 2008). Moreover the Cerenkov Telescope Array (CTA) which is now in its design phase, is also planed to be based on PMT's. However, there are some disadvantages to the PMT technology: the rather poor quantum efficiency, the use of high voltages, the high cost when used in large number in a matrix arrangement and the large weight. Hence, we have investigated the possibility to design future Cerenkov telescopes based on solid state technology, specifically Geiger avalanche photodiodes. In a preliminary developmen

“…A calibration signal from a pulsed and temperature-stabilized light emitting diode can be monitored continuously and, if a change in amplitude is detected on a certain channel, the voltage of the corresponding pixel is modified to readjust the amplitude. Special power supply modules have been developed for this task [9], which can communicate with the camera control software (see also section III) via an USB interface and allow the bias voltage of each pixel to be regulated individually 3 . In addition, a water cooling system has been installed.…”

“…The G-APDs are coupled to this plate by a thermally 2 The NSB light produces a permanent current in a serial resistor of the readout electronics and thereby reduces the effective bias voltage, which is supplied through the FEBs. 3 Since four G-APDs are combined in one pixel, they have been selected such that their nominal operating voltages are within ±10 mV. This translates into gain variations of a few percent [6].…”

A novel camera type for very high energy gamma-ray astronomy based on Geiger-mode avalanche photodiodes

et al. 2009

View full text Add to dashboard Cite

Geiger-mode avalanche photodiodes (G-APD) are promising new sensors for light detection in atmospheric Cherenkov telescopes. In this paper, the design and commissioning of a 36-pixel G-APD prototype camera is presented. The data acquisition is based on the Domino Ring Sampling (DRS2) chip. A sub-nanosecond time resolution has been achieved. Cosmic-ray induced air showers have been recorded using an imaging mirror setup, in a self-triggered mode. This is the first time that such measurements have been carried out with a complete G-APD camera.
