标题： The Under-Water Dark-Room Experimental Facility at the University of Winnipeg

摘要： 2021年至2023年期间，在温尼伯大学建造了一个全新的水下暗室测试设施（UWDTF），用于测试设备、光学组件和探测器，这些设备可能被用于不同的水下实验中，例如超级神冈探测器（Hyper-K）以及其他实验。 该设施主要设计用于与不同校准系统相关的研究和开发活动，这些校准系统将在欧洲核子研究中心的水切伦科夫试验实验（WCTE）、日本东海的中间水切伦科夫探测器（IWCD）以及日本神冈的超级神冈远端探测器中使用。 该设施设有一个大型水箱（1000加仑），位于一个光学隔离的房间内，并配备了一个吊架，可以在水箱内提供最大50磅负载的三维运动。此外，还设计了一个定制的云台系统，以在极地和方位方向上为负载提供更多的运动自由度。 除了许多其他研究和开发活动外，该设施主要用于测试为Hyper-K实验设计的水下相机外壳。这里介绍了在此多功能水下暗室设施中进行的相机校准的初步结果，首先描述了该设施的关键特性。 显示英文摘要

摘要： A completely new under-water dark-room test facility (UWDTF) has been built at the University of Winnipeg during 2021-2023, for the testing of the equipments, optical components and detectors before they might be used in different underwater experiments, like the Hyper-Kamiokande (Hyper-K), and others. The Facility is designed for Research and Development activities primarily related to the different calibration systems, which are/will be used in the Water Cherenkov Test Experiment (WCTE) at CERN, the Intermediate Water Cherenkov Detector (IWCD) at Tokai, Japan and the Hyper-Kamiokande Far Detector at Kamioka, Japan. The facility houses a large tank of water (1000 gallons) in an optically isolated room, and is equipped with a gantry that provides for the 3D motion of a maximum of 50 lbs of load inside the tank. A customized pan-tilt system has also been devised to accommodate further degrees of freedom of motion to the payload in the polar and azimuthal direction. The facility is primarily used for testing of the under-water camera housings designed for the Hyper-K experiment, besides many other research and development activities. The preliminary results of the camera calibration done in this multi-purpose underwater-darkroom facility are presented here, starting with the description of the vital features of this facility.
