一个280毫升的液氢目标已建成和测试的MUSE实验在PSI调查质子电荷半径通过同时测量弹性μ子质子和弹性电子质子散射。为了将系统的不确定性控制在低于百分之一的水平，对目标周围的材料数量及其温度稳定性进行了严格的限制。目标系统于2018年底在PSI的调试运行期间成功运行。目标温度稳定在0.01K水平。这表明密度稳定性在0.02%水平，这比所需的好大约十倍。
A 280 ml liquid hydrogen target has been constructed and tested for the MUSE experiment at PSI to investigate the proton charge radius via simultaneous measurement of elastic muon–proton and elastic electron–proton scattering. To control systematic uncertainties at a sub-percent level, strong constraints were put on the amount of material surrounding the target and on its temperature stability. The target system was successfully operated during a commissioning run at PSI at the end of 2018. The target temperature was stable at the 0.01 K level. This suggests a density stability at the 0.02% level, which is about a factor of ten better than required.
