Presentation Transcript

  1. Data Collection Using Database Sequencing Keith Brister CARS The University of Chicago

  2. biocars.org • NIH/NCRR supported resource for protein and virus crystallography managed by The University of Chicago • Monochromatic and MAD • BSL-2 and BSL-3 capable • Laue • Time-resolved Crystallography

  3. Administrative Database • Accounts are assigned to research groups • Access requires group name and password (something known) as well as an “Access Key” (something owned)

  4. CARS Proposal System (CARPS) People Samples Chemicals Enter, Update, Show PUBLICATIONS! Interact with Operations Database (Staff Only) Act for another user (Staff Only) Prepare Proposals for Review (Staff Only) Spam-O-Matic™ (Staff Only) Select Referees and Review Proposals (Staff Only) ANSTO Uses this System to Review Proposals for Travel Funding (Staff Only) Complete Calendar and Scheduling Tools (Staff Only) Proposals Trips

  6. The Trip Page • People Coming • Samples Coming • Chemicals Coming • Access to archived data • Set up data collection • Run data collection

  7. Operational Database Beamline Controls User Interface Old Beamline Control Model Proposal and Administrative Database

  8. New Approach Beamline Controls and the User Interface • The Need? • Interfaces require a complete knowledge of the low level beamline control code and/or the mastering of inventive interprocess communications protocols. This limits the number of people who are able to contribute to the project. • Although many excellent interfaces for MAD and monochromatic crystallography exist, we also need to support user experiments and staff projects for which no interface currently exists.

  9. New Beamline Control Model UI written in convenient modern language with database query support. In a pinch, a spreadsheet program can be used. User Interface Administrative and Operational Databases Combined databases provide access control and simplified remote collaboration. Sequence engine A generic engine sends the appropriate commands to the beamline control software. Beamline Controls Currently running the insertion device station with this model

  10. Data Sequencing Detail User Interface Frame DB Frame 1 Frame 2 Frame 3 Frame 4 … Status DB Sequence Engine Beamline Controls

  11. Edit Page: New Sequence Select type of Sequence Select “New Sequence” Enter Directory Name Enter File Prefix Click here to generate the sequence

  12. Monochromatic Sequence Select type of Sequence Select “New Sequence” Enter Directory Name Enter File Prefix Start first frame at this angle Increment Starting angle by this amount. Click here to generate the sequence

  13. Press here when ready. This only appears if you currently have beamtime. Defined Time-resolved Sequence To delete an entire sequence, confirm YES and click here. Click here to remove unexposed frames. If all frames are unexposed (or marked to retake) then you will get the Loops screen. If needed, enter new directory and press “Change sequence Parameters” Download the sequence as a spreadsheet file. Edit these commands if needed Mark frames to be retaken here. This will change “Collected” back to “Ready” for the selected frames.

  14. Start data collection Stop after this frame Become Master Run Page Current Clock Hutch/Station Cameras Select a Sequence to Run Control Run Time Parameters

  15. Remote Collaboration Tool

  16. Where is this going? • Current Development • EPICS interface • Remote access and control • Remote Collaborations • Stand-alone Detector Support (In use at GSECARS) • Implementation of BNL PX interface • Support for Other Facilities • Generalized system in beta test (ChemMatCARS) • Interface to APS II system • Open source • carps.sf.org (Source Forge site under construction) • Sequence engines for non-EPICS beamline control systems • Interfaces for other experiments
