New VME based data acquisition systems for nuclear physics experiments at Inter University Accelerator Centre

The new VME based data acquisition system have been designed and developed to fulfil the need of the Nuclear physics experimental setups at IUAC using commercial analog to digital converters (ADC), time to digital converter (TDC), Scalar, charge to digital converter (QDC) etc., along with the in-house developed DAQ software, the VME crate controller module and the event identifier module. The new DAQ has enabled us to move from a multi-crate CAMAC based DAQ to the single crate VME system due to use of enhanced multi-channel high density electronics like the ADCs and TDCs while multi-crate option do exist in VME crate controller. This has helped in significant reduction in space requirement and the neat cabling for the signal processing for large experimental setup
