一种通过吸管漂移管内的气体超压简单拉伸阳极丝的新技术将所需的吸管重量减少到绝对最小。我们的探测器将由3000多根吸管组成，填充直径为1米，长度为30厘米的圆柱形跟踪体积。投影的空间分辨率为200μm。总质量小于15 kg的探测器将在真空中运行，但仅增加3 mm的聚酯薄膜壁厚。探测器的设计，生产经验和初步结果将进行讨论。
A novel technique to stretch the anode wire simply by the gas over‐pressure inside straw drift tubes reduces the necessary straw weight to an absolute minimum. Our detector will consist of more than 3000 straws filling up a cylindrical tracking volume of 1m diameter and 30cm length. The projected spatial resolution is 200μm. The detector with a total mass of less than 15kg will be operated in vacuum, but will have an added wall thickness of 3mm mylar, only. The detector design, production experience and first results will be discussed.
