Development and commissioning of the 30 ps time resolution MEGII Pixelated Time detector (in session "Solid State Detectors - Poster Session") Development of a high voltage power supply for detectors using photo-diode (in session "Front, Trigger, DAQ and Data Management - Poster session"). The four-anode detector produces a significant increase in detection/counting efficiency over that for a single-anode detector. In this work a times increase in detection efficiency is demonstrated. The multi-anode detector is also used as a diagnostic tool to optimize transmission of the ion optics.
The PET detector consisted of an 8 x 8 array of 3 x 3 x 15 mm 3 LYSO crystals with an 8 x 8 array of 3 x 3 mm 2 SiPMs. The crosstalk, energy linearity, energy resolution and coincidence resolving timing (CRT) at different SiPM pixel positions were measured . The SSPM timing jitter was determined using down-conversion pairs, whose intrinsic time correlation—typically 1 ps —allows for precise relative timing measurements. As shown in Fig. b, a jitter of ≈ ns was reported by measuring coincidences between an SSPM and a commercial single-photon counting module (EG&G SPCMPQ); the timing resolution in these early measurements .

The Multi-Anode Microchannel Arrays (MAMAs) are a family of photoelectric photon-counting array detectors, with formats as large as ( x )-pixels that can be operated in a windowless. The MAMA, or Multi-Anode Microchannel Array, Timothy and Bybee,is available in many versions and sizes, Timothy et al., A MAMA tube having by pixels on each side is planned for a second generation Hubble space telescope detector.
The device used in this system is a multi-anode readout application specific integrated circuit (ASIC) for a microchannel plate (MCP) (Langstaff and Chase ). An array of anodes on a 25 µm. Third-generation, x and x pixel multianode microchannel MAMA detectors are under development for satellite-borne FUV and EUV observations, using pixel dimensions of 25 x 25 microns.
An account is presently given of the configurations, modes of operation, and recent performance data of these systems. KEYWORDS: Microchannel plates, Sensors, Detector arrays, Electrodes, Electronics, Ultraviolet radiation, Space telescopes, Space operations, Aerospace engineering.

SPIE.Materials, Manufacturing, and Measurement for Synchrotron Radiation Mirrors. The detection of a single photon is the most sensitive method for sensing of photon emission. A common technique for single photon detection uses microchannel plate arrays combined with photocathodes and position sensitive anodes.
Here, we report on the combination of such detectors with grating diffraction spectrometers, constituting a low-noise wavelength resolving photon spectroscopy.

Orbiter TPS development and certification testing at the NASA/JSC 10MW Atmospheric Reentry Materials and Structures Evaluation Facility W. ROCHELLE, H. BATTLEY. However, more and more types of single photon-counting detector arrays are developed to obtain spatial information in recent years, such as SPAD arrays, microchannel plate photomultipliers (MCP-PMTs) [14,15], multi anode photomultipliers (MAPMTs), silicon photomultiplier (SIPM) arrays.
Current instruments used to detect specific protein-protein interactions in live cells for applications in high-content screening (HCS) are limited by the time required to measure the lifetime.
Here, a 32 × 1 single-photon avalanche diode (SPAD) array was explored as a detector for fluorescence lifetime imaging (FLIM) in HCS. Device parameters and characterization results were interpreted in.this external photoelectric effect and are superior in response speed and sensitivity (low-light-level detection).
They are widely used in medical equipment, analytical instruments and industrial measurement systems. Light sensors utilizing the internal photoelectric effect are further divided into photoconductive types and photovoltaic types.However, the cost, rate limitation, aging and cross-talk in multi-anode devices at high BW are problems.
There are several groups working on these issues, so progress is likely. Table 6 summarizes the author's opinion of pros and cons of various detectors presented .
