Dust containing radioactive materials dispersed following the Fukushima nuclear power plant accident in March 2011. Gamma-rays are emitted in the process when unstable nuclei in the materials decay. Based on the technology of Si/CdTe Compton Camera, we have manufactured a quick prototype model for the use in the field. The camera, now called an ``Ultra-Wide-Angle Compton Camera'' was...

The Compton camera is a viable and convenient tool used to visualize the distribution of radioactive isotopes that emit gamma rays. After the nuclear disaster at the Fukushima Daiichi power plant in 2011, a large amount of radioactive isotopes (e.g. 134Cs, 137Cs) was released and widely dispersed, thus making the removal thereof is still an urgent task. In response, we are proposing a portable...

The Soft Gamma-ray Detector (SGD) is one of the ASTRO-H instruments and will feature wide energy band (60--600 keV) at a background level 10 times better than instruments currently in orbit. The SGD achieves low background by combining a Compton camera scheme with a narrow field-of-view active shield. The Compton camera in the SGD is realized as a hybrid semiconductor detector system which...

Deep submicron CMOS technologies of the 130 nm generation are now the baseline choice to implement front-end electronics for tracking detectors, while the R&D in the 65 nm node is starting. In such technologies, new analogue to digital converters achieving 8-10 bit resolution, 50-100 MHz sampling frequency and 1mW of power have been demonstrated both by the industry and in the academia. This...

For the phase 1 upgrade of the CMS experiment the front end electronics of the pixel detector will be replaced to improve the readout efficiency at high luminosity. The redesign of the readout chip that is bump-bonded to the silicon sensor is an essential part of this upgrade. The first prototype versions of the new readout chip have been designed and produced. The results of the complete...

The CBC2 is the latest version of the CMS Binary Chip ASIC for the readout of the upgraded CMS Tracker at the High Luminosity LHC. It is designed in 130nm CMOS with 254 input channels and will be bump-bonded to a substrate to which sensors will be wire bonded. The CBC2 is designed to instrument double layer modules, consisting of two overlaid silicon microstrip sensors with aligned...

Recently, we have developed a series of analog front-end ASICs for readout of semiconductor detectors such as CdTe, Si, and APD. While the main objective is to develop instruments for astrophysical observations, the same technology can be used in other fields. In this paper, we describe development of a 40 channel high counting rate ASIC, and its application to heavy-ion beam monitoring in...
