FPIX is an X-ray deector using 64 chqnnel Si-APD(avalanche photodiode) linear arry.
Purpose and Vision
1. Ultra-fast signal processing : Sub-nanosecond width pulse & 10-GHz waveform sampling
試作されたSi-APDアレイの写真。このアレイ素子は64個のピクセルからなり、1個のピクセルは100μmx200μm、厚さ10μmである。
2. Signal read-out for >103 pixels: Ultra-fast analog memory & Low Temperature Co-fired Ceramics board
3. Fast-response X-ray detector: Si-APD linear array detector (ramdaT:100 ps)& two-dimensional detector with stacking the linear arrays.

Summary
A new circuit board for 64 channel Si-APD linear array detector was developed for us the 1 nano sec time-resolved X-ray experimants.
The circuit board consisted of an ultra-fast frontend application-specific integrated circuit (0.8-μm BiCMOS process), field-programmed gate array (Xilinx Spartan6), and hardware-based transmission control protocol processor for Gigabit Ethernet (SiTCP). We tested the performance of the multi-scaling measurements using the detector system at the Photon Factory beam line BL-14A.
