How the GaGe Digitizer was used: Data acquisition was facilitated by a GaGe / Compuscope CS220 digitizer card, which performed analogue-to-digital sampling of radar waveforms. The radar, mounted on a Kenn Borek Aviation DHC-6 Twin Otter aircraft, transmitted radio frequency signals and received echoes to map out profiles of power in time delay.
How the GaGe Digitizer was used: The GaGe Digitizer played a key role in upgrading the diagnostic system for measuring Ion Cyclotron Emission (ICE) on the DIII-D tokamak. This digitizer allowed for capturing detailed ICE spectra by integrating with robust magnetic pickup loops placed near the plasma’s edge. The upgrade enabled the collection of comprehensive data, including frequency, amplitude, mode polarization, and toroidal mode number.
How the GaGe Digitizer was used: A gas-phase argon ionization detector prototype was built to determine the feasibility of measuring small recoil energies and to characterize the recoil spectrum of argon nuclei. Calibrations were performed using a low-energy x-ray source, and a planned measurement will involve the recoil spectra from a 60keV Lithium-target neutron generator at LLNL. The detector prototype enables the study of scintillation properties of argon and investigation of electron and nuclear recoils.

How the GaGe Digitizer was used: The spectrometer employs a special technique called optically switched dual-wavelength cavity ring-down spectroscopy (OSDW-CRDS). It uses a waveguide optical switch to rapidly switch between two wavelengths, detecting different forms of methane. This helps mitigate noise from temperature and frequency fluctuations, resulting in more precise measurements.
