Data Acquisition and Signal Processing

Oral

Research at the DIII-D National Fusion Facility in San Diego focuses on short pulse plasma discharges that specialize on various shaping profiles. High speed data collection is a critical component for the operation of many of DIII-D’s diagnostics. This is fundamental for capturing high resolution data used in experimental data analysis. Differing techniques enable the plasma control system...

126. A more flexible design for MDSplus Device drivers

Data Acquisition and Signal Processing

Oral

The traditional approach to building MDSplus Device drivers is rigid and lacks the ability to meet changing needs. In this paper, we introduce a novel paradigm for Device driver development that allows the tree structure to dynamically change.

This allows device drivers that can reconfigure to automatically reflect the hardware it represents, or a device that implements a variable number of...

107. Updating the Build, Test, and Deploy systems for MDSplus

Data Acquisition and Signal Processing

Oral

In order to better support development efforts on MDSplus, we needed to improve the Continuous-Integration/Continuous-Deployment (CI/CD) systems building MDSplus. To that end, we have created a new Jenkins server, utilizing the new scriptable Jenkinsfile method and modern security principles. Additionally, we have moved off of autotools, and on to CMake for our build system. Existing tooling...

117. The Control and Data Acquisition System of the DTT experiment

Data Acquisition and Signal Processing

Oral

DTT, Divertor Tokamak Test facility, is currently under construction at the Frascati ENEA Research Center. Its aim is to explore alternative solutions for the extraction of the heat generated by the fusion process. Its Control and Data Acquisition System (CODAS) will (1) orchestrate and synchronize all the DTT systems during Plasma operation and maintenance; (2) acquire data from the...

108. Plasma Boundary Shape Reconstruction Using Visible Spectroscopy Diagnosis on EAST Tokamak

Data Acquisition and Signal Processing

Oral

Plasma shape control is a prerequisite for the stable operation of tokamak devices. Future fusion reactors anticipated to have longer burn length and higher discharge performance, current shape reconstruction methods based on magnetic diagnostics will encounter challenges related to signal drift and probe maintenance.
Hence, a plasma boundary shape reconstruction system utilizing visible...
