本文介绍了在中微子工厂中用高能质子短脉冲轰击固体靶时，对钽丝和钨丝在热冲击下的寿命和强度进行的试验。给出了使用激光多普勒测振仪进行寿命试验和高温、应力和应变率下动态强度特性测量的结果。测试表明，固体钨靶的寿命至少为3年，加上其他有益的特性，使其成为中微子工厂的绝佳候选者。
A description is given of tests on tantalum and tungsten wires to evaluate their lifetime and strength under the thermal shock that will be experienced when a solid target is bombarded with short pulses of high energy protons in a Neutrino Factory. The results of lifetime tests and measurements of dynamic strength characteristics at high temperatures, stresses and strain rates using a laser Doppler vibrometer are given. The tests show that a solid tungsten target will have a life of at least 3 years, which, with other beneficial characteristics, make it an excellent candidate for the Neutrino Factory.
