我们研制了一种直径30毫米、厚1毫米的大而薄的固体氢靶(SHT)，用于质子从不稳定核的弹性散射。通过使用在低温下具有高导热系数的对氢，我们可以防止由于较高温度环境的辐射而在目标中心升华。在长期的散射实验中使用了均匀的SHT，并保持了它的形状和厚度。
We have developed a large, thin solid hydrogen target (SHT) that is 30 mm in diameter and 1 mm thick for elastic scattering of protons from unstable nuclei. By using para-H2that has a high thermal conductivity at low temperatures, we could prevent sublimation at the target center due to radiation from the higher temperature surroundings. The uniform SHT was used during long-term scattering experiments and it maintained its shape and thickness.
