To address the challenges of low SNR and artifacts in image reconstruction in Compton imaging, we have developed a silicon pixel detector capable of measuring recoil electron tracks. This detector consists of an 18 µm-pitch, 450 µm-thick silicon PIN sensor manufactured by HORIBA and an ASIC fabricated using TSMC’s 250 nm CMOS technology. The ASIC generates digital triggers when the energy deposition in a pixel exceeds a threshold, allowing for the readout of only the pixels associated with the electron track. This functionality enables the measurement of electron tracks within the scatterer and synchronization between the scatterer and absorber in Compton cameras. This presentation will detail the structure and basic performance of this detector.
