New Developments for the Trigger-Time-Event System for the W7-X Experiment

Since the first plasma operation in 2015, the superconducting fusion experiment Wendelstein 7-X has successfully completed 4 experiment campaigns (OP1.1, OP1.2a, OP1.2b, and OP2.1). The machine maintenance phase was completed at the end of January 2024, followed by the commissioning of W7-X. The sta...

Description
Summary:Since the first plasma operation in 2015, the superconducting fusion experiment Wendelstein 7-X has successfully completed 4 experiment campaigns (OP1.1, OP1.2a, OP1.2b, and OP2.1). The machine maintenance phase was completed at the end of January 2024, followed by the commissioning of W7-X. The start of the scientific plasma operation phase OP2.2 is planned for September 2024. The Trigger Time Event (TTE) system is used by the central control systems, the technical components and the diagnostics of W7-X for their time synchronization, for processing events, and for generating and receiving trigger signals. This use cases makes it necessary to adapt the TTE system to the changing requirements of users. After an introduction to the functions and structure of the TTE system, this contribution describes the current expansion status of the TTE system and the planned modifications and expansion of the hardware and software of the TTE system. Finally, the current status of the planned work on the TTE system for the upcoming W7-X operational phase OP2.2 is presented. The contribution ends with a summary.
