July 28, 2017 - The recent installation of a Camera Data Acquisition (DAQ) System at NCSA is a major milestone for early integration of Data Management (DM) software with LSST Camera hardware. This single board system, constructed by the camera team at SLAC and intended to read out the camera, was installed in a rack at NCSA last week, connected through a NCSA-provided DAQ Client and Management (Linux) host. The integrated system is currently emulating a camera, acquiring images which can be read out using custom API software. Jim Parsons, NCSA Level 1 System Lead for LSST, worked with SLAC DAQ physicist Gregg Thayer to ensure the DAQ is fully accessible and the software reliable. The complete system will require 14 such boards to read out the full 3.2 Gpix LSST camera. The remaining boards will be constructed and delivered to DM in February of 2018. Mike Huffer, Subsystem Manager for Data Acquisition at SLAC, was proud of the team and pleased with the preparations and results of this milestone event. The full system will be delivered next year; meanwhile this hardware prototype from SLAC will remain at NCSA for further testing.
Concurrent with the DAQ installation event, a small workshop on data acquisition and system integration was held at NCSA and attended by Data Management, Telescope and Site, and additional Camera staff.

Financial support for LSST comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded LSST Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA). The DOE-funded effort to build the LSST camera is managed by the SLAC National Accelerator Laboratory (SLAC).
