| Outline of Final Research Achievements |
We have developed the high density integration technique for 2-dimensional gaseous detectors with readout ASIC’s using screen printing technologies. 8 strips each in vertical and horizontal directions as well as their connections with input ports for frontend electronics are made as a course of the screen printing on an FR-4 printed circuit board, where a readout ASIC are pre-mounted.
The developed printed circuit board and a GEM (Gas Electron Multiplier) have been assembled as a 2-dimensional gaseous detector. The detector was tested by irradiating X-lays from 55Fe and the X-lay spectrum was successfully measured. By injecting test pulses at the far ends of strips, conduction of strips and contacts with input ports of the ASIC were also confirmed observing output signals from the readout ASIC.The screen printing technique with the precision of 100um pitch, which is required for connections to practical ICs, has been demonstrated.
