FNPL Spectrometer Recalibration

چکیده
After initial checks, I noticed egregious differences between the apparatus as I found it and earlier literature. A thorough investigation then ensued to establish a new calibration factor (and to uncover when the calibration factor changed). The rest of this document details these measurements, but the final conclusion of this work is to find that the beam momentum relates to the spectrometer current as pc/I = 1.614MeV/A. Before we delve into the sundries of these measurements, a quick calculation based on simple approximations is provided and reveals nearly the same result.

Wavelength calibration of spectra measured by the Global Ozone Monitoring Experiment by use of a high-resolution reference spectrum.
Earthshine spectra measured by the nadir-viewing Global Ozone Monitoring Experiment (GOME) spectrometer aboard the second European Remote Sensing (ERS-2) Satellite in the range of 240-790 nm are widely used for the retrieval of concentrations and vertical profiles of atmospheric trace gases. For the near-real-time delivery of ozone columns and profiles at the Royal Netherlands Meterological Ins...
متن کاملShort-Wave Near-Infrared Spectrometer for Alcohol Determination and Temperature Correction
A multichannel short-wave near-infrared (SW-NIR) spectrometer module based on charge-coupled device (CCD) detection was designed. The design relied on a tungsten lamp enhanced by light emitting diodes, a fixed grating monochromator and a linear CCD array. The main advantages were high optical resolution and an optimized signal-to-noise ratio (0.24 nm and 500, resp.) in the whole wavelength rang...
متن کاملThe Impact of Feedback on the Different Time Courses of Multisensory Temporal Recalibration
The capacity to rapidly adjust perceptual representations confers a fundamental advantage when confronted with a constantly changing world. Unexplored is how feedback regarding sensory judgments (top-down factors) interacts with sensory statistics (bottom-up factors) to drive long- and short-term recalibration of multisensory perceptual representations. Here, we examined the time course of both...
متن کاملA Matched Comparison Across Three Different Sensory Pairs of Cross-Modal Temporal Recalibration From Sustained and Transient Adaptation
Sustained exposure to an asynchronous multisensory signal causes perceived simultaneity to shift in the direction of the leading component of the adapting stimulus. This is known as temporal recalibration, and recent evidence suggests that it can occur very rapidly, even after a single asynchronous audiovisual (AV) stimulus. However, this form of rapid recalibration appears to be unique to AV s...
متن کاملA computer-assisted metal analyser using flow injection coupled with direct current plasma–optical emission spectroscopy
An automated routine method was developed for the determination of trace metals using a flow injection system into a direct current plasma spectrometer. The characteristic emission in the 'Spectra- Metrics' three-electrode jet is channelled through an echelle grating to the detector of the instrument. The emission signal is continuously recorded, and, after digitalization, calculated and record...
