Diamond Light Source is the UK's national light source , currently the capability for preparing all but the most inactive samples on site does not exist, making it hard for Users who wish to do experiments that involve manipulation of samples at the point of measurement to do experiments with radioactive samples at the facility.We will build and equip an active materials laboratory to enable users to manipulate and prepare most active samples to measure on the Diamond synchrotron beamlines. The laboratory will have a dry lab for materials preparation such as engineering materials used in nuclear power stations, a wet lab to handles samples in solution or in contact with solution such as environmental samples. The lab will have a dedicated counting room to check the activity of the samples brought or made on site and also a safe storage room. We will also procure a cell and oven suitable for the loading rig being acquired by I12 to enable active materials mechanical properties to be examined at temperature in particular atmospheres. This cell and oven are necessary to understand the impact of prolonged radiation of the mechanical performance of a range of materials used in nuclear fission and fusion facilities.The laboratory will enable a wide range of experimental research on the synchrotron using active materials including engineering studies of advanced materials after irradiation , understanding the behaviour of radionuclides when encapsulated in materials such as glass for storage as waste. Understanding the way radionuclides behave in the environment to influence clean-up strategy after accidental or deliberate release of radionuclides in the environment.

钻石光源是英国的国家光源，目前的能力，准备所有，但最不活跃的样品在现场不存在，我们将建立并装备一个活性材料实验室，使用户能够操作和制备大多数活性样品在钻石同步加速器光束线上测量实验室将有一个干实验室用于材料制备，如核电站使用的工程材料，一个湿实验室用于处理溶液中的样品或与溶液接触的样品，如环境样品。实验室将有一个专门的计数室，以检查现场带来或制作的样品的活性，还有一个安全的储存室。我们还将采购适用于I12正在采购的装载装置的电池和烘箱，以使活性材料的机械性能能够在特定气氛的温度下进行检查。该实验室将使人们能够对使用活性材料的同步加速器进行广泛的实验研究，包括对辐照后的先进材料进行工程研究，了解放射性核素封装在玻璃等材料中作为废物储存时的行为。了解放射性核素在环境中的行为方式，以便在放射性核素意外或故意释放到环境中后影响清理战略。
