国际μ子电离冷却实验（MICE）目前在英国卢瑟福阿普尔顿实验室运行，旨在演示μ子电离冷却原理，以应用于未来的中微子工厂或μ子对撞机。我们介绍了原始数据和重建数据的移动和管理框架的现状。原始数据移动器设计用于在数据文件被写出后立即将其安全地上传到永久磁带存储上。该过程已实现自动化，并内置检查以确保传输每个阶段数据的完整性。数据处理框架最近经过重新设计，以便提供重建数据的快速周转以进行分析。自动重建在 MICE 控制室的专用机器上执行，任何重新处理均在二级网格站点完成。结合此次重新设计，设计并实现了新的重构数据移动器。我们还审查了专为 MICE 设计的强大数据库系统的实施情况。数据处理，无论是原始数据还是蒙特卡罗数据，都需要准确了解实验条件。 MICE 具有多种复杂元素，从束线磁体到粒子识别探测器再到超导磁体。配置数据库包含任何给定时间的实验条件（磁体电流、吸收材料、探测器校准等）信息，以确保准确且可重复的模拟和重建。一个完全复制的热备份数据库系统已经实现，其中一个受防火墙保护的读写主机在控制室运行，一个只读从机在不同的位置运行。实际的数据库通过 Web 服务层对最终用户隐藏，该层提供独立于平台和编程语言的数据访问。
The international Muon Ionization Cooling Experiment (MICE) currently operating at the Rutherford Appleton Laboratory in the UK, is designed to demonstrate the principle of muon ionization cooling for application to a future Neutrino Factory or Muon Collider. We present the status of the framework for the movement and curation of both raw and reconstructed data. A raw data-mover has been designed to safely upload data files onto permanent tape storage as soon as they have been written out. The process has been automated, and checks have been built in to ensure the integrity of data at every stage of the transfer. The data processing framework has been recently redesigned in order to provide fast turnaround of reconstructed data for analysis. The automated reconstruction is performed on a dedicated machine in the MICE control room and any reprocessing is done at Tier-2 Grid sites. In conjunction with this redesign, a new reconstructed-data-mover has been designed and implemented. We also review the implementation of a robust database system that has been designed for MICE. The processing of data, whether raw or Monte Carlo, requires accurate knowledge of the experimental conditions. MICE has several complex elements ranging from beamline magnets to particle identification detectors to superconducting magnets. A Configuration Database, which contains information about the experimental conditions (magnet currents, absorber material, detector calibrations, etc.) at any given time has been developed to ensure accurate and reproducible simulation and reconstruction. A fully replicated, hot-standby database system has been implemented with a firewall-protected read-write master running in the control room, and a read-only slave running at a different location. The actual database is hidden from end users by a Web Service layer, which provides platform and programming language-independent access to the data.
