A general-purpose digital data acquisition system (GDDAQ) has been developed at Peking University. This GDDAQ, composed of 16-channel Digital Pulse Processor Pixie-16 modules from XIA LLC, is a versatile, flexible, and easily expandable data acquisition system for nuclear physics research in China. The software used by this GDDAQ is based on the CERN ROOT framework and developed and tested in CentOS 7 LINUX operating platform. A flexible trigger system has also been developed to accommodate different experimental settings. A user-friendly software GUI helps users monitor and debug the detection system in real timer or offline. Many offline analysis tools have been developed to help users quickly optimize parameters for various types of detectors without the need for time-consuming tests and measurements. This GDDAQ has been successfully implemented in several nuclear physics experiments and its versatility and high efficiency have been demonstrated.

• If you have any comments or suggestions for this project(function addition or improvement), please send an email to Hongyi Wu([email protected]).
• We will improve the Chinese/English manuals of the software as soon as possible. Currently, we mainly explain the use of the software through our demonstration.

This manual applies only to XIA LLC Pixie-16

• This program is developed by the Group of Experimental Nuclear Physics, Peking University.
• The earliest graphical interface development of this program is based on NSCL DDAS Nscope.
• Thanks to Hui Tan's(XIA LLC) support for our development.

The development of this program is supported by the following：

• XIA LLC
• Institute of Modern Physics, Chinese Academy of Sciences(IMP)
• China Institute of Atomic Energy(CIAE)
• The University of Hong Kong(HKU)
• Shandong University, Weihai(SDU)
• ...

This program is applicable to XIA Pixie16 module, which supports the 100/250/500 MHz sampling rates(specifically, information about the module can be found in File->About in the graphics software) and supports up to 8-chassis synchronous operation, that maeans, at least 1600-channel signals are simultaneously collected. This package requires the CERN ROOT6 version and the resolution display above 1920x1080.

The program is designed to be compatible with the 100/250/500 MHz modules. Simply add the firmware location of the corresponding sample rate modules to cfgPixie16.txt. The program can automatically identify the module's type and load the corresponding firmware.

Currently we have tested most types of modules, so you can run the type of modules of our tested by default. To support other types, please contact XIA LLC to obtain the corresponding firmware or contact Hongyi Wu([email protected]).

• The main control interface development based on the ROOT GUI is highly complex, which is difficult for users to modify now. It is not easy for users to develop their own version based on this program.
• We are also developing acquisition software for online/offline analysis based on web control:
  • Qt
  • ZeroMQ
  • JSROOT
  • ...
