Software modules of DAQ PCI board (DeLiDAQ) for positive-sensitive MWPC detectors with delay line readout

The data acquisition system for the position-sensitive delay line detectors on basis of the reprogrammable PCI DAQ board (DeLiDAQ) began to be used for scientific measurements with one- and two-dimensional position-sensitive MWPC detectors on the neutron reactors IBR-2 (JINR, Dubna) and BERII (HMI, Berlin). A stand-alone version of the system with the graphical user interface on the basis of packet ROOT can be used on any PC with the operating system Windows 2000 or Windows XP. Architecture of the created software ensures several ways of interfacing to experiment control systems. In the paper we provide a description of the DeLiDAQ software modules, their features and results of some performance tests.
