Extreme Ultraviolet Polarimetry with Laser-Generated High-Order Harmonics
… positioning system that places harmonics on the microchannel plate detector with an accuracy of 0.3 mm, which allows a spectral resolution of about 180. We have demonstrated that reflectance as low as 0.2% can be measured at EUV wavelengths and that this data is repeatable to within the error of …

Study of Electron-Impact Induced Fragmentation of Thymine
… time-of-flight mass spectrometer with a microchannel plate detector is used to detect and mass resolve the positively charged fragments. LabVIEW based data acquisition techniques are used to accumulate the time-of-flight data as a function of electron impact energy. The work described in …

Low-Energy Electron Impact Fragmentations of the Polycyclic Aromatic Hydrocarbon Anthracene
… time-of-flight mass spectrometer with a microchannel plate detector is used to mass-resolve and detect the fragment ions. A multichannel scaler card is used for acquiring single mass spectra. Data acquisition is controlled by LabVIEW code, which ramps the electron impact energy from 0 to …

Construction and calibration of a custom time-of-flight mass spectrometer and its use in measuring the reaction kinetics of transition metal ion-organic interactions.
… The revelatory hardware for our instrument is a microchannel plate detector (MCP). The MCP is mounted on the exit of a custom designed and built hemispherical energy analyzer (sector), which acts as an energy filter. This filtering characteristic of the sector permits study of selected ionized …

Development of an Apparatus for the Study of Electron Impact Fragmentation of Molecular Clusters
… time-of-flight mass spectrometer with a microchannel plate detector. Neutral metastable fragments are detected using a channeltron with appropriately biased meshes in front to avoid the detection of charged particles. For both types of fragment data acquisition takes place using a …

Enabling Validation of a CubeSat Compatible Wind Sensor
The Ram Energy Distribution Detector (REDD) is a new CubeSat-compatible space science instrument that measures neutral wind characteristics in the upper atmosphere. Neutral gas interactions with plasma in the ionosphere/thermosphere are responsible for spacecraft drag, radio frequency disturbances …
