The aim of the T2K experiment is to measure the oscillation of muon-type neutrinos, produced by a high-intensity proton beam, into electron-type neutrinos. This will complete the characterisation of the 'mixing matrix' for neutrinos (the only fundamental particles of the Standard Model known to change identity during propagation). This requires two detectors, a 'far detector' to observe the beam after oscillation (T2K uses the well-known and well-understood Super-Kamiokande detector) and a 'near detector' to characterise the beam before oscillation. The near detector will be built on the JPARC accelerator site, and the contributions of the UK groups include the construction of the Electromagnetic Calorimeter for the experiment, as well as major contributions to electronics, data acquisition, and the designs for the target and beam dump. Sheffield has responsibilities for parts of the ECAL and for the the so-called 'Light Injection system' for the DsECAL, P0D and Barrel ECALs. This system is based on pulsed LED strips and is designed to inject known quantities of light into the ECALs for calibration purposes. The RA requested is required to contribute to this effort.

T2 K实验的目的是测量由高强度质子束产生的μ子型中微子振荡成电子型中微子。这将完成中微子（标准模型中唯一已知在传播过程中改变身份的基本粒子）的“混合矩阵”的表征。这需要两个探测器，一个“远探测器”用于观察振荡后的光束（T2 K使用众所周知的Super-Kamiokande探测器），一个“近探测器”用于观察振荡前的光束。近距离探测器将建在JPARC加速器场地上，英国小组的贡献包括为实验建造电磁量热计，以及对电子学，数据采集以及目标和束流收集器设计的主要贡献。谢菲尔德负责部分ECAL以及DsECAL、P0 D和Barrel ECAL的所谓“光注入系统”。该系统基于脉冲LED灯带，旨在将已知量的光注入ECAL中用于校准目的。要求RA为这一努力做出贡献。
