摘要：

In this work we present an alternate concept of a fast-pulsed valve which is convenient for molecular-beam spectroscopy and gas puffing in plasma assemblies. The valve operates at repetition rates up to 100 Hz with repetitive high-intensity 100-μs FWHM pulses. Its efficient closed magnetic circuit with low power consumption permits a high-repetition-rate operation. The very light mass-spring assembly allows for rather narrow repetitive pulses. The valve has a small size and is self-sealed for use with corrosive gases. A fast PVDF pyroelectric detector was used for diagnosis.
