HILTRAC Archives

HILTRAC apparatus schematic and inset photos. The apparatus schematic highlights the moveable Chamber 1, the path of the UV photolysis laser (light blue), the reservoir with gas inlets (purple arrows), the USF produced from the nozzle, and the intersection of the flow with the DFCS (red) and LIF (green) optical axes. The top inset photos show the reservoir with Laval nozzle (left) and the Pitot tube mounted on the YZ translation stages (right). The bottom inset photo shows an interior picture of the chamber, with the X translation stage for the reservoir visible on the internal breadboard, the two optical axes for LIF and DFCS overlapping with the UV photolysis laser, and the cage-mounted LIF collection optics. A red diode laser shows the approximate path of the infrared frequency comb laser beam as it reflects off the gold mirrors for the Herriott multipass configuration. -- physics.chem-ph

Design and Implementation of a New Apparatus for Astrochemistry: Kinetic Measurements of the CH + OCS Reaction and Frequency Comb Spectroscopy in a Cold Uniform Supersonic Flow

by Keith CowingJune 11, 2024June 11, 2024

We present the development of a new astrochemical research tool HILTRAC, the Highly Instrumented Low Temperature ReAction Chamber. The instrument is based on a pulsed form of the CRESU (Cinétique […]
