Data Management at the ALS Print

Users of the ALS are responsible for meeting their data management obligations to their home institutions and granting agencies. Except as noted below for data stored at NERSC, the ALS does not provide specific resources to manage data that are generated through user experiments. Because the ALS does not have a facility-wide data archiving service or staff to manage the data, the user must generally make arrangements to copy data to their own storage systems or move the data to their home institutions.

Staff form the ALS, ESNest, and Berkeley IT have recently developed protocols for managing data in real time, see Data Transfer Considerations for ALS Scientists and Users, for more information.

The ALS facility provides infrastructure such as networks and computers at the beamlines located on the ALS experimental floor. These resources may differ at individual beamlines and users should consult with the beamline staff to understand the capabilities at the beamline that they will be using.

Individual beamlines may have specific resources and data management practices to help users meet their data management needs and obligations.  Users should consult beamline staff when formulating data management plans and strategies. The beamline resources do not substitute for the user’s responsibility for their data. Data storage on beamline equipment is only temporary and cannot be relied upon for archival purposes.

The ALS is participating in a data pilot program with the National Energy Research Scientific Computing Center (NERSC), where user data sets may be stored. If users have data at NERSC, then the data management strategy and policies of NERSC must be followed. Users should consult beamline staff to determine if that beamline is storing data at NERSC.
