First Use of a Polarized ^3he Neutron Spin Filter on the Back-n White Neutron Source of CSNS
China Spallat Neutron Source | Chinese Acad Sci | 1 Zhongziyuan Rd | Indiana Univ
Abstract
Polarized eV neutrons can address interesting scientific questions in nuclear physics, particle physics, and astrophysics/cosmology. We present the first experiment to polarize the neutrons on the Back-n beamline at the Chinese Spallation Neutron Source (CSNS) using an in-situ NSF using spin-exchange optical pumping (SEOP) of 3 He. A 3 He polarization of 68%+/- 0.7% for this in-situ NSF was measured through neutron transmission method at Back-n. This is high enough to enable new experiments on the Back-n beamline.

- 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
