Compton camera used in the Hitomi SGD is a useful detector for soft gamma-ray in space observation. Si-pixel sensor with 3.4 mm pixe;s are used as scatterer in the SGD Compton camera. But this pixel size does not allow us to measure a direction of Compton-recoil electrons in the Si sensor, and thus the sensitivity is limited.

The LHC has recently been upgraded to operate at higher energy and luminosity. In addition, there are plans for further upgrades. These upgrades require the optical links of the experiments to transmit data at much higher speed in a more intense radiation environment. We have designed a new optical transceiver for transmitting data at 10 Gb/s. The device consists of a 4-channel ASIC driving a...

Low Gain Avalanche Detectors (LGAD), are customised Avalanche Photodiodes (APD) to obtain a high electric field region confined close to the reversed junction. As a consequence, only the electrons generated when an incident particle passes through the detector start the impact ionization. Thus multiply the charge collected by readout electronics without increasing the noise in the signal. Due...

Compton imaging is a promising gamma-ray imaging method because of its collimator-less detection and the application to medical field is expected. However the imaging capability for distributed sources is still under investigation because of its low signal to noise ratio derived from Compton cones.

Radiation hardness improvement of FD-SOI MOSFETs has been investigated in terms of positive charge compensation in buried oxide (BOX) by applying back-gate bias. In general, the radiation tolerance of SOI MOSFET is low in total ionizing dose (TID) because the relatively thick oxide, BOX, exists underneath the MOSFETs and the positive charge generated in the oxide by the irradiation. Then,...
