Nano-optoelectronic sensors and devices bring tremendous revolutions in photoelectric conversion due to dimension reduced. The device geometry dominates the electron transport so that the spatially resolved optoelectronics properties are critical to characterize device performance. In this paper, it reports a two-photon pulsed laser scanning microscopy method which utilizes raster scan on device with...
STiC3 is a mixed mode Application Specific Integrated Circuit (ASIC) for high resolution timing readout of Silicon Photomultipliers (SiPMs). It is designed for Time-of-Flight (ToF) applications in medical imaging and High Energy Physics experiments and has been developed in the framework of EndoToFPET-US project. The STiC3 chip uses the UMC 180 nm CMOS technology and has a differential structured...
The analog digital converter (ADC) designed in UMC 0.18 µm CMOS technology is dedicated to the SiPM analog readout frontend “KLauS” developed before for the international linear collider (ILC) scintillator-based analog hadron calorimeter (AHCal). In order to make the carlorimeter as compact as possible, an extremly low power consumption is required by the AHCal such that active cooling can be avoided...
We present the first commissioning data of our TOF-PET test device featuring MPPC read-out of small size LFS crystals. We discuss the characteristics of the test device and present results from two different multi-channel read-out ASIC chips which offer a high timing performance.
Silicon photomultipliers (SiPMs) are a novel type of solid state photon detectors with similar internal gain factors as Photomultiplier Tubes (PMTs). Due to their low operation bias voltage, magnetic field immunity and small size, these new silicon photon detectors can be used for a wide range of applications, in particular Positron Emission Tomography (PET). Using combined crystal/SiPM systems for...
We demonstrate a THz-biochip integrated with a compact high-efficiency micro-THz source with tunable THz frequencies for direct, sensitive, localized label-free bio-sensing. The capability to identity different illicit drug powders is successfully demonstrated.
