Applications of Cherenkov light emission for dosimetry in radiation therapy / by Adam Kenneth Glaser
Since its discovery in the 1930's, the Cherenkov effect has been paramount in the development of high-energy physics research. It results in light emission from charged particles traveling faster than the local speed of light in a dielectric...

Cherenkov imaging and biochemical sensing in vivo during radiation therapy / by Rongxiao Zhang
While Cherenkov emission was discovered more than eighty years ago, the potential applications of imaging this during radiation therapy have just recently been explored. With approximately half of all cancer patients being treated by radiation at...

In vivo fluorescence imaging and tomography methods to quantify metastatic burden in lymph nodes / by Alisha Viola DSouza
Morbidity and complexity involved in lymph node staging via surgical resection and biopsy could ideally be overcome using node assay techniques that are non-invasive. Visible blue dyes, fluorophores and radio-tracers are often used to locate the...

Nonlinear theory of the Cerenkov maser.
Cherenkov radiation. ; Maser physics.
The Cerenkov Maser radiation is examined using linear and nonlinear theory. Linear theories for the gain in the single particle and the collective limits have been given previously. In this work, we show the connections between these two operating...

Gain experiments with a grating based free electron laser.
Free electron lasers -- Experiments. Wave guides -- Design and construction. Diffraction gratings -- Experiments. Electron beams. Infrared sources.
The far infrared region of the electromagnetic spectrum, 15-3000 Œºm in wavelength, has a paucity of narrow band laser sources. To address the issue of whether a grating based free electron laser could operate well as such a source, a grating...

Image reconstruction optimization and quantification for image-guided luminescent tomography / by Robert William Holt.
Molecular imaging of cancer features is a critical part of advancing better tools for oncology management and drug discovery, yet it is still evolving as a useful tool. Diffuse Fluorescence Tomography (FT) is one approach to molecular imaging, used...

Fine structure in auroral radio emissions.
Ionospheric radio wave propagation -- Observations. Hiss (Radio meteorology). Auroras -- Antarctica -- Observations.
A VersatIle Electromagnetic Waveform (VIEW) receiver was deployed at South Pole station in December 2002 in order to measure the fine structure of auroral radio emissions with high resolution and an unprecedented 500-1000 kHz bandwidth. Using this...

Superradiant Cerenkov source: theory and experiment.
Free electron lasers. ; Cherenkov radiation. ; Far infrared lasers. ; Lasers -- Resonators.
In the far infrared region of the electromagnetic spectrum, 15-3000 μm in wavelength, there is a lack of narrow band sources. The Cerenkov free electron laser (CFEL) shows promise to fill this gap. The Cerenkov resonator was analyzed theoretically...
