Abstract

Integrated circuits (ICs) are widely used in spacecraft and are concerned with the probability of Single Event Effects (SEEs). To accurately locate the SEE-sensitive area of ICs, we have designed Hi’Beam-SEE for the single event effect experiment terminal at heavy-ion facilities. The Hi’Beam-SEE consists of three sub-systems: the heavy ion positioning system is responsible for locating the position of each particle within the beam, the single event detection system detects the SEEs that occurred in the device under test, and the online tracking algorithm extracts and reconstructs the position of each particle that triggers SEEs. The beam test with 84Kr18+ particles demonstrates the heavy ion positioning system can achieve a spatial resolution of 4 μm in measuring every single particle’s position. Also, the single event detection system can identify SEEs correctly and issue triggers with good timing accuracy. The online tracking algorithm can process 172 frames that contain tracks per second and extract the positions with an accuracy of 3.2 μm. In addition, it attains a rejection factor of 93.6% while keeping the signal efficiency of 99%. This paper will discuss the design and performance characterization of the Hi’Beam-SEE.

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
