Abstract

The beam from K130 room temperature cyclotron is being extensively used for nuclear physics experiments for last three decades. The typical beam energy for the experiments is approximately 7-10MeV/nucleon for heavy ions and 8-20MeV/nucleon for light ions. The number of detectors used, may vary from one channel to few hundreds of detector channels. The proposed detector system for experiments with the superconducting cyclotron may have more than 1200 detector channels, and may be generating more than one million parameters per second. The VME (Versa Module Europa) and CAMAC (Computer Automated Measurement and Control) based data acquisition system (DAQ) is being used to cater the experimental needs. The current system has been designed based on various commercially available modules in NIM (Nuclear Instrumentation Module), CAMAC and VME form factor. This type of setup becomes very complicated to maintain for large number of detectors. Alternatively, the distributed DAQ system based on embedded technology is proposed. The traditional analog processing may be replaced by digital filters based FPGA (Field Programmable Gate Array) boards. This paper describes the design of current DAQsystem and the status of the proposed scheme for distributed DAQ system with capability of handling heterogeneous detector systems. © 2012 by the respective authors.
