| 英文摘要 | The belle ii experiment at the future superkekb collider in tsukuba, japan, features a design luminosity of 8 . 10(35) cm(-2)s(-1), which is a factor of 40 larger than that of its predecessor belle. the pixel detector (pxd) with about 8 million pixels is based on the depfet technology and will improve the vertex resolution in beam direction by a factor of 2. with an estimated trigger rate of 30 khz, the pxd is expected to generate a data rate of 20 gbytes/s, which is about 10 times larger than the amount of data generated by all other belle ii subdetectors. due to the large beam-related background, the pxd requires a data acquisition system with high-bandwidth data links and realtime background reduction by a factor of 30. to achieve this, the belle ii pixel daq uses an fpga-based computing platform with high speed serial links implemented in the atca (advanced telecommunications computing architecture) standard. the architecture and performance of the data acquisition system and data reduction of the pxd will be presented. in april 2016 and february 2017 a prototype pxd-daq system operated in a test beam campaign delivered data with the whole readout chain under realistic high rate conditions. final results from the beam test will be presented. |
