3.1 Activities

• The months of January and February continued as an extended engineering period focusing on Technical Operations maintenance and upgrades and integration of the VTF instrument. The VTF group from KIS Germany arrived on Maui on January 8 and will be there integrating the VTF through the end of February.

• The DKIST Directorate continued work on the DKIST section of the NSO 2024 Annual Program Plan (APP). The 2024 NSO APP was submitted to NSF on

• The DKIST Deputy Associate Director attended the AAS 2024 Winter meeting in New Orleans, LA.

• The DKIST Director was on Maui for most of January and FebruaryFor the month of June, DKIST continued weeks 2-6 of OCP2.7 science observing.

• The DKIST Directorate prepared for and presented to the NSO User’s Committee on January 18, 2024.

• The DKIST Directorate held a FY 2024 Q2 planning meeting with the DKIST senior leadership.

• The DKIST Directorate prepared for and presented to the AURA Solar Observatory Council on February NSF’s 2-year extension proposal review held June 4-6, 2024.

4.7 Science Operations Tools

• Robert Tawa Completed the beta version of the new Experiment architect and released it for testing by the science users.

• began working on the EA templating - gathering requirements and gaining an understanding of how the scientists buid experimenets and were the time reduction can be easily made.

• Removed the calls to from Ops tools related to the “proposal completion” message, which had been stripped from the ICD previously

• Completed a backend update to Docker v25.0.3

4.7.1 Management

• Robert Tawa Provided Operational support to the science team related to proposal call cycle.

• Prepared and delivered slides for the NSF review relating to the work that the OT software team did and was currently doing in supprot of science Ops.

• Vestibule Design and Fabrication/Construction solicitation

  • Received quote for Vestibule Steel Fabrication. Followed up with other vendors.

• Reviewed 50% design package for elevator vent redesign

  • Corresponding with M3 on any questions they may have regarding the elevator vent louvers. Need to take more pictures when time and techs are available.

  • Completed Kick-Off meeting with M3 for elevator vent redesign. Sent out the precast sealant and elevator submittals.

• Power outage support/recovery; Restarted Regular, Generator, and UPS, communication, and thermal systems.

• Chiller 02 urgent troubleshooting, leak in system 2 resulted in lost refrigerant charge

  • JCI fixed cracked tee in System 2 discharge line and recharged refrigerant

  • RFQ for service contract, vendor rep visit onsite.

• Chiller 05/06 PM and troubleshooting visit

  • Both chillers wer tuned, topped off, inspected

  • Found a facility flow switch misbehaving

  • Both circuits on CH06 were low, circuit 2 had a leak at the pressure relief valve connection

7 Data Center Operations (Bob and Alisdair)

7.1 Hardware Infrastructure

• implemented an upgrade to the Asgaard and Dev stack to the Pacific version in preparation/test for deployment to the production stack

7.2 Software Infrastructure

7.2.1 Data Center

• Prepared for and presneed the Data Center status to the NSF review panel

• Updated the DHS-DC Interface Control Document to address the need for packaging small files into .tar files for faster and more efficient transfer of data from the summit to the data center

• updated the Dkist processing stack and REST APIs to Pydantic 2

• Scaled airflow out to 256 workers

• Installed a new metrics stack - including storage and collection of metrics relating to the infrastructure.

7.2.2 Portal/Archive/Public

• Created a list of actionable improvements to the portal from user feedback and began implementing them

• Made searches based on Proposal ID and Experiment case insensitive

7.3 Science Data Processing

7.3.1 Calibration Pipelines

• VBI

  • investigated the failure of the VBI pipeline related to the receipt and attempted processing of VBI mosaic pattern with a mosaic pattern that was not N x N (5 mosaic locations). this mode of VBI operation had not been encountered previously

• Cryo-NIRSP

  • Redesigned and implemented the Processing Preparation Worker to include Cryo-NIRSP

  • Refactored the solar gain task to preform fringe correction based on a parameter

• DL NIRSP

  • Generated integration tests for the DL-NIRSP Pipeline in preparation for he beta version release

  • Updated the current pipeline to reflect the use of the MISI in the newest data
