Beam Measurement with Synchrotron Radiation for BEPCII Storage Ring | |
|
||
| The detail of Synchrotron Light Monitor for BEPCII storage ring is introduced. The Synchrotron Light Monitor measures both transverse beam profiles and longitudinal bunch length. Transverse profiles are measured by visible light imaging and spatial interferometer, and longitudinal bunch length is measured by streak cemera and intensity interferometer. | ||

An Upgrade for the Bunch Current Measurement System of BEPCⅡ | |
|
||
| Recently, the BCM (Bunch Current Measurement) system is being developed at BEPCⅡ(Beijing Electron-Positron ColliderⅡ). In order to solve the instability problems which frequently happen in the existing system, we have upgraded the DAQ system with new ADC card and new DSP arithmetic in FPGA. In addition, some discussion for the upgrade such as the generality of the arithmetic, easy to change operation mode, noise reduction measurements, and so on, are also presented in this paper. | ||
