Technologies for High Speed Data Handling in the ATST

The Advanced Technology Solar Telescope (ATST) has some very demanding data handling requirements. Sixteen high speed camera lines are available, each capable of transmitting data at up to 1 gigabyte per second. Camera lines must be fully isolated from each other in order to cope with the high data volume, yet be defined dynamically on a per-experiment basis, providing the ability to route data through various real-time data processing/reduction and quality assurance nodes as needed. This paper discusses the investigation and technologies chosen to deliver on those requirements.
