Operations Considerations in Designing a High Speed Multi Channel Data Acquisition System
Abstract
The increasing demand for more complex and sophisticated data acquisition systems in the Sandia fusion research program, along with high shot rates, requires that the systems be engineered to operate as efficiently, flexibly, and reliably as possible. The Operations Research group, Division 1254, of Sandia Labs is now involved in the design of the DAS for PBFA-II. A DAS is needed that can meet the daily data acquisition needs of the facility. This system must remain flexible to meet the changing needs of the program without sacrificing reliability or accuracy. Towards these ends, several unique features are being implemented in the PBFA-II DAS. Set up efficiency has been improved by a cable harness that easily allows any of over 700 signals to be cabled to more than 100 waveform channels. Flexibility has been increased by a trigger and fiducial patch panel switching system that quickly enables any of the 18 triggers and fidus to be connected to any of the waveform channels. Reliability has been improved by a specially designed cooling system and a modular system design approach.
