我们报告了 KLOE 漂移室小型原型在磁场中的束流测试。该室使用 90% He–10% iC4H10 气体混合物运行。研究了漂移时空关系。无磁场时的平均空间分辨率约为 110 μm，0.6 T 磁场下的平均空间分辨率约为 120 μm。报告了初级电离和漂移速度的测量结果。还讨论了 He 基气体混合物中 dE/dx 的测量。
We report on a beam test of a small prototype of the KLOE drift chamber in magnetic field. The chamber was operated with a 90% He–10% iC4H10gas mixture. Drift space–time relations were studied. The average spatial resolution is about 110 μm in the absence of magnetic field and 120 μm in a 0.6 T magnetic field. Measurements of the primary ionization and drift velocity are reported. The measurement of dE/dx in a He-based gas mixture is also discussed.
