Abstract

Radio Frequency Solid-State Amplifiers (RFSSA) will replace the oscillators supplying SPIDER, MITICA and the ITER HNB RF ion sources. In order to verify the operation of the amplifiers on a significant load for the appli-cation and to identify possible integration problems in advance, special tests on a Resonant Dummy Load (RDL) able to mimic the ion source characteristics were foreseen. This paper will present the RDL conceptual design and the special tests that will demonstrate the design and operation of the RFSSA first unit in normal and abnormal conditions, and its integration to mitigate risks before on-site commissioning.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
