An S-band cavity bpm is designed for a new injector in National Synchrotron Radiation Laboratory. A re-entrant position cavity is tuned to the TM110 mode as position cavity. Cut-through waveguides are used as pickups to suppress the monopole signal. Theoretical resolution of this design is 31 nm. A prototype cavity bpm system is manufactured for off-line cold tests. The wire scanning method is used to calibrate the bpm and estimate the performance of the on-line bpm system. A cross-talk problem has been detected during the cold test. Racetrack cavity bpm design can be used to suppress the cross-talk. With the nonlinear effect being ignored, transform matrix can be used to correct cross-talk. Analysis of cold test results shows that the position resolution of prototype bpm is better than 3 μm.

In order to pursue high-precision beam position measurements for free-electron laser facilities, a cavity beam position monitor(Cbpm) is employed to measure the transverse position that can meet the requirement of position resolution at a sub-micrometer or even nanometer scale. However, for the pill-box cavity bpm, crosstalk between the cavities will have an effect on the accurate measurement of beam position. To reduce the effect of crosstalk on Cbpm performance and ease the measurement of the isolation between the cavities, the cavities with a slight difference in resonant frequency were designed and applied in the Dalian coherent light source and Shanghai soft X-ray free-electron laser facilities. Furthermore, two methods, the principal component analysis method and the method of harmonic analysis, are proposed in this paper to evaluate the crosstalk. The results demonstrate that the two methods are feasible in evaluating the crosstalk between the cavities.

Controlled stability of proteins is a highly efficient mechanism to direct diverse processes in living cells. A key regulatory system for protein stability is given by the ubiquitin proteasome pathway, which uses E3 ligases to mark specific proteins for degradation. In this work, MYB56 is identified as a novel target of a CULLIN3 （CUL3）-based E3 ligase. Its stability depends on the presence of MATH-BTB/POZ （bpm） proteins, which function as substrate adaptors to the E3 ligase. Genetic studies have indicated that MYB56 is a negative regulator of flowering, while bpms positively affect this developmental program. The interaction between bpms and MYB56 occurs at the promoter of FLOWERING LOCUS T （FT）, a key regulator in initiating flowering in Arabidopsis, and results in instability of MYB56. Overall the work establishes MYB transcription factors as substrates of bpm proteins, and provides novel information on components that participate in controlling flowering time in plants.

The four electrodes in the stripline beam position monitor(bpm) for Hefei Light Source(HLS II) storage ring are of axially symmetric type. We have derived a new calibration method of electrode gains for this type stripline bpm. The gain fit error of different data grids was analyzed, and the ±5 mm by ±5 mm grid is the *** electrode gains of two stripline bpms(HLS II SR-BD-STLB1 and HLS II SR-BD-STLB2) were obtained based on offline calibrated data. The results show that data after fitting gains are improved, with the electrode gains being between 0.94 and 1.15.

The wake field, impedance and output signal for SSRF bpm have been calculated and analyzed by us-ing the numerical simulation code of MAFIA. The narrow-band impedance of bpm arising from formation of reso-nance in its cavity like structure either is harmful to beam or limits the performance of bpm itself, and should be re-duced to tolerable levels. The calculated results show that there are three main peaks in the impedance spectrum ofthe SSRF bpm prototype, and two of which are above the limit. After lots of simulations for different shapes of thebpm button, a new structure of SSRF bpm have been found, and there is only one main peak, which is under thelimit, in the impedance spectrum. Its output signal also meets the requirement.

An S-band cavity bpm is designed for a new injector for HLS (Hefei Light Source). It consists of two cavities that work on 2448 MHz: a re-entrant position cavity tuned to TM110 mode and a reference cavity tuned to TM010 mode. Cut-through waveguides are used as pickups to suppress the monopole signal. Simulations with different assumption of dimension change are performed to evaluate errors caused by mechanical error and give general tolerance. Design of electronics is given. Theoretical resolution of this design is 31 nm.
