We have developed a prototype of new mass data acquisition system (P-MDAS) that can perform a faster data acquisition. This system is based on a general-purpose PXI (Compact PCI) bus standard. In 2004, standalone vivifications on the performance of P-MDAS were carried out (8- channel ADC, hard disk streaming). In 2005 and 2006, we examined its performance under the following environments: under remote diagnostic control using optical communication interface, under multiple controller PCs, under multiple PXI boards to increase the number of channels, under a long duration of data acquisition (45 seconds) with a high sampling rate (1 MHz) and a high resolution (14 bit). At the same time, we developed a MDAS server (UNIX WS) and verified its performance on the data transfer to Inter-Shot Processor. We are planning to increase the number of channels and conduct a performance verification of overall data processing system (DPS) with 10 GB/Shot of data acquisition.
