We have developed a compact imaging system for GEM detectors, which is applied to thermal neutron imaging. A GEM chamber and a readout board are integrated into one device. The detector is connected to a readout PC with Gigabit Ethernet. This system generates image data of 14.4K pixel from 240 signals employing strip readout method. We have measured performance of the developed system with a pulsed...
We are developing a neutron beam monitor with a gas electron multiplier (GEM) for the high-intensity total diffractometer at J-PARC. In order to analyze the basic characteristics of the GEM-based detector, a neutron irradiation test was carried out at J-PARC. The wavelength-spectrum distribution obtained from the test is consistent with the calculations, and the beam profiles agree with the simple...
We are developing a new gaseous detector with Gas Electron Multiplier (GEM) as a gamma camera for biomolecular analysis and medical applications. Our system consists of the gamma conversion layers (gold) and the amplification layers. In order to know the performance of the prototype gamma camera, gamma-ray irradiation test was performed with radioactive source of 99mTc (141 keV). 2D images were obtained...
