Highly reliable 3He gas detectors are most often used in neutron scattering experiments but have disadvantages such as low count rates and low position resolutions. In this study, a 3He gas detector system called NEUNET-HCR was developed, whose count rate is approximately 10 times that of the current NEUNET system, which was developed for a high position resolution with a low count rate. NEUNET-HCR achieved a maximum count rate of 535 kcps per detector, with a loss of approximately 30%. As the NEUNET-HCR system was developed based on the NEUNET system, various improvements were required to achieve the high count rate. Further, a high count rate was achieved in the NEUNET-HCR system without significantly degrading the position resolution.

Due to its high position resolution and fast speed, the position sensitive detector (PSD) is widely applied in micro displacement measurement. However, almost all PSDs suffer from high nonlinearity. In this paper, three kinds of PSDs and their advantages and disadvantages are introduced. Then principle of pin-cushion PSD is studied, based on which a new signal processing system is designed. The signal processing system consists of a high-precision sensor circuit and a software system integrated with a correction algorithm. The test result shows the linearity of the PSD is greatly improved.

Position Sensitive

Position Sensitive Detector (PSD) is a new type of photoelectric position sensor. Compared with traditional CCD, PSD has high position resolution, simple circuit and fast response. Operational principle of PSD and how it can be used in vibration system are firstly shown in this paper. Based on the MCU, a vibration measurement system using a BOS-PSD0220 type sensor is designed. The system is then experimentally measured at the most sensitive area of PSD. The result is compared with data calculated by MATLABLE, which demonstrates PSD is a good choice for vibration measurement.
