Abstract

The aim of this study was to determine the best setting for measuring time-of-flight in TMP with a streak-camera. In the first setting, referred to as straight setting, the laser, TMP sample and streak-camera were in a line. In the second setting, referred to as diagonal setting, the streak- camera was placed at a 90-degree angle to the light source. The results indicate that the diagonal setting allows an easier time-of-flight measurement than the straight one in low-consistency TMP. In medium-consistency TMP, however, there are no performance differences between the settings. Nevertheless, if drift in the laser or streak-camera necessitates the use of a reference pulse, the straight setting provides an easier measurement. Neither setting allows the measurement of high-consistency TMP.
