摘要
To cope with the high bunch crossing rates of future particle accelerators, new detectors must have short recovery times. We measured the transit time of drifting photoelectrons in straw tubes of 2.5 mm radius for magnetic fields ranging from 0 to 8 T. Six different gas mixtures, primarily CF4 based, were studied. Long transit times and signal degradation indicate the need for careful choices in detector design.
