Beam position measurement system can not only provide the beam position monitoring, but also be used for global orbit correction to reduce beam loss risk and maximize acceptance. The Beam Position Monitors (BPM) are installed along the synchrotron to acquire beam position with the front-end electronics and data acquisition system (DAQ). To realize high precision orbit measurement in the main heavy ion synchrotron and cooling storage ring of heavy-ion research facility in Lanzhou (HIRFL-CSRm), a series of alignment and calibration work has been implemented on the BPM and its DAQ system. This paper analyzed the tests performed in the laboratory as well as with beam based on the developed algorithms and hardware. Several filtering algorithms were designed and implemented on the acquired BPM raw data, then the beam position and resolution were calculated and analyzed. The results show that the position precision was significantly improved from more than 100 μm to about 50 μm by implementing the new designed filtering algorithm. According to the analyzation of the measurement results and upcoming physical requirements, further upgrade scheme for the BPM DAQ system of CSRm based on field programmable gate array (FPGA) technology was proposed and discussed.

The novel nanozyme has been used in the detection field as biosensor, but has also been employed in newfields like antibacterial and inhibiting of biofilm growth applications. This paper reports the rapid preparationof the nanozyme PS-CDs-MnO2 with oxidase activity by using PS-CDs as reducing agent to reduceKMnO4. The mechanisms of positive electrical property of PS-CDs-MnO2 and the single linear oxygen(1O2) have promised the broad-spectrum antibacterial ability and high efficiency in eliminating bacteria,with 48 h long-term antibacterial effect. The minimum inhibitory concentration (MIC) againstStaphylococcus aureus (S. aureus), Bacillus subtilis (B. subtilis), Escherichia coli (E. coli) and Pseudomonasaeruginosa (P. aeruginosa) at 7.50 lg/mL, 60 lg/mL, 15 lg/mL and 60 lg/mL, respectively. The preparedPS-CDs-MnO2 could effectively inhibit the formation of S. aureus biofilm at the concentration of 10 lg/mL. The visually sensitive and selective sensing platform based on PS-CDs-MnO2-TMB was established, andrealized the colorimetric detection of tiopronin (TPN) with a detection range at 285.71 nM–14.28 lMand detection limit at 6.30 nM. This research provides a good theoretical and practical basis for the preparationof oxidase nanozyme and its application in detection, antibacterial and inhibition of biofilm formationfields.
