Gas phase reaction chamber (GPRC) for pump-probe spectroscopy

GPRC is an instrument for performing photodissociation experiments and gas phase reactions at low pressures (~1x10-4 Torr). The chamber incorporates an pulsed Even-Lavie gas valve (Amsterdam Cantilever Piezo Valve ACPV2/ACPV3) as a source for high intensity supersonic beam (jet cooled molecules, 20 microsec gate up to 5 kHz), large capacity turbo molecular pump capable of handling corrosive gases (STP-IS2207c CF200, 2200 l/s N2, magnetically levitated, Edwards), pressure gauges, integrated optical breadboard and optics for combining XUV and visible/terahertz pulses, optics for collecting photofragment fluorescence, fiber optic probe for fluorescence monitoring and motorized vacuum-compatible mirror mounts for accurate alignment of pump and probe pulses. Additional ports are also available for external device mounting (e.g. mass spectrometer) and various feedthroughs.
