MicroFM Fast Silicon Photomultiplier Family

Fast Silicon Photomultiplier DetectorsThe MicroFM family features SensL’s state-of-the-art M-series silicon that features a uniquely fast output signal. This fast output can have rise times of ~100ps and recovery times of <1ns, allowing for precision timing and fast count rates. The MicroFM series is available in four detector sizes (0.25mm,1mm, 3mm and 6mm) and two types of package: either a TO-18 can or a new custom-designed, 4-side tileable surface-mount (SMT) package that is compatible with lead-free, reflow soldering processes.

The MicroFM detectors are based on the silicon photomultiplier concept and form a range of high gain, single-photon sensitive, visible-light sensors. They have performance characteristics similar to a conventional PMT, while benefiting from the practical advantages of solid-state technology: low operating voltage, robustness, compactness and insensitively to light over-exposure. More information on the MicroFM devices and their operation can be found in the MicroFM User Manual.

OUTPUT SIGNALS

The oscilloscope shots below show examples of measured waveforms from the fast output of different detector sizes and using a 2.5GHz bandwidth oscilloscope and a 50MHz, 50ps red (650nm) laser. No amplifier was used, and the output was directly connected to the oscilloscope using a 1m long, 50W coaxial cable.

PIN ADAPTER (MicroFM-SMTPA-XXXXX)

The SMT Pin Adapter board (SMTPA) is a small PCB board that houses the SMT detector and has through-hole pins to allow its use with standard sockets. This product is useful for those needing a quick way to evaluate the SMT package without the need for specialist surface-mount soldering. While this is a ‘quick fix’ suitable for many evaluations, it should be noted that the pins will slightly degrade the timing performance and if the best possible timing performance is required, the MicroFM-SMA-XXXXX is recommended.

The SMTPA comes with a SMT detector soldered on to it. Therefore, the part must be ordered with a detector type specified by using the last digits of the part number, e.g. “-XXXXX” becomes “-30035” if the 3mm, 35µm detector is required. Please see the Ordering Information on pages 6 - 7 for the full range of product options and further details.

SMA BIASING BOARD (MicroFM-SMA-XXXXX)

The MicroFM-SMA is a simple board designed to allow evaluation of the MicroFM SMT range of SPM detectors. The board has SMA connectors for connecting the bias voltage and the output signal. The biasing and output line is laid out in such a way as to preserve the fast timing characteristics of the detector. A version of this board is also available with the TO-18 detector mounted (MicroFM-XXXXX-SMA-X18).

The MicroFM-SMA is recommended for users who require a plug-and-play set-up to quickly evaluate FM-series SMT detectors with optimum timing performance. The board provides an output which can be connected directly to the oscilloscope or measurement device.

The SMA board comes with a SMT or TO-18 packaged detector soldered on to it. Therefore, the part must be ordered with a detector type specified by using the last digits of the part number, e.g. “-XXXXX” becomes “-30035” if the 3mm, 35µm detector is required. Please see the Ordering Information on pages 6 - 7 for the full range of product options and further details.

TILING OF THE SMT PACKAGE

SensL has developed a market-leading, custom SMT package for the M-series Micro detectors. It is a compact, leadless, chip-scale package that is compatible with lead-free, reflow soldering processes. A clear encapsulant is used to provide a smooth flat surface for optimal coupling to scintillators.

The dead-space between the detector chip and the edge of the package has been minimized resulting in a package that can be tiled on 4 sides. This allows multiple devices to be configured into unique layouts for a wide range of custom applications. Two-dimensional tiling examples are illustrated below for the 3mm and 6mm package. The distance between active areas is typically ~1mm when tiled, but actual alignment and placement tolerances will depend on the accuracy of the user’s assembly process. A Technical Note is available that gives advice on creating arrays of the SMT detectors.
