我们描述了在由超级因瓦合金组成的样品上进行的测量，该合金是与强流脉冲质子束结合使用的坚固固体靶的候选材料。低的热膨胀系数是使Super-Invar成为一个有吸引力的候选目标的特性。我们已经在布鲁克海文直线加速器同位素生产设施对我们的样品进行了辐射。描述了热膨胀系数随辐射损伤的变化的试验。高辐射剂量对其低的热膨胀系数是严重不利的。
We describe measurements performed on samples consisting of the alloy Super-Invar, which is a candidate material for a robust solid target used in conjunction with an intense pulsed proton beam. A low coefficient of thermal expansion is the characteristic property which makes Super-Invar an attractive target candidate. We have irradiated our samples at the Brookhaven Linac Isotope Producer facility. Tests for variations of the thermal expansion coefficient as a function of inflicted radiation damage are described. The high radiation dose is severely detrimental to its low coefficient of thermal expansion.
