基于LabVIEW微扰法场分布测量系统的设计及实现
Nuclear Electronics & Detection Technology(2012)
Abstract
加速腔的机械制造过程中,产生的各种形变会使加速腔的谐振频率偏移目标频率,使得场分布不均,大大限制了加速梯度的提高,故而需要对加工好的加速腔的场分布进行测量和调整,针对北京大学射频超导实验室对多单元(cell)超导椭球加速腔以及轮辐(spoke)超导加速腔场分布的测量需求,在NI公司的LabVIEW8.5开发环境下,利用VISA与RS - 232、GPIB接口通信实现了对电机的控制及矢量网络分析仪的数据读取,进而研制了一套用于微扰法的场分布测量系统,并对2cell加速腔进行了测量和误差分析.

- 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
