固体和气体中的质子阻止本领测量，通常使用质子加速器、货车de Graf机器等进行，已经存在了几十年，许多元素和化合物。我们提出了一种新的方法，使这种类型的测量使用不同的源，即质子束产生的高强度短脉冲激光。这种类型的源的优点是，有大量的粒子和短束长度，这是理想的发展中的介质，如热致密等离子体的测量。我们的测量结果与现有的数据和理论相一致，验证了这种方法。
Proton stopping power measurements in solids and gases, typically made using proton accelerators, Van de Graf machines, etc., have existed now for many decades for many elements and compounds. We propose a new method of making this type of measurement using a different source, namely proton beams created by high intensity short pulse lasers. The advantage of this type of source is that there is the high number of particles and short bunch lengths, which is ideal for measurements of evolving mediums such as hot dense plasmas. Our measurements are consistent with exiting data and theory which validates this method.
