Plastic scintillation detectors for precision Time-of-Flight measurements of relativistic heavy ions

“…Moreover, a combination of time-to-analog converter (TAC) with anolog-to-digital converter (ADC) currently has an advantage over time-to-digital converter (TDC) for signal digitization due to a better sampling resolution. Attempts [13,14] were also made by replacing the conventional electronics by waveform digitizers, which have the clear advantages in recording the full event signals but so far are still limited by their sampling rates.…”

Barriers to infrastructure sustainability for mountainous townships in Chongqing

“…The development of mountainous townships relies largely on the improvement of infrastructure conditions [5,6]. However, it is appreciated that the sustainability performance of infrastructure is poor in Chinese townships especially in mountainous regions [7]. Liu et al [8] suggested that mountainous townships usually have insufficient infrastructures, especially environmental infrastructure, and ineffective maintenance practice because of short-term behavior, which leads to typical problems such as short lifespan and serious environmental pollution.…”

“…Kumar [1] pointed out that the construction regulations in mountainous regions should be made according to mountainous characteristics. The studies by other researchers investigate the effects of the geographic characteristics of mountainous regions on their economic development [2,7,10]. On the other hand, China's township serves as central places in rural China [4].…”

“…In study the townships in China, Gu et al [4] pointed out that townships usually are weak in revenue making, lack of authority to self-govern and lack of economic activities. Liu et al [7] indicated the shortage of infrastructures for the development of mountainous townships. It can be seen from the previous researches that the principle of infrastructure sustainability has been well addressed, but the backgrounds of mountainous townships have not been incorporated.…”

Waveform timing performance of a 5 GS/s fast pulse sampling module with DRS4

“…Then we evaluate its timing performance in a cosmic ray setup with plastic scintillators and fast PMTs. The timing performance is also compared with that of a Lecroy 10 GS/s oscilloscope [26] in a similar setup for evaluation of possibilities to improve timing performance of TOF systems [27].…”
