Default High Power Wideband Gyrotron Backward Wave Oscillator Operating towards the Terahertz Region

From The DNP-NMR Blog:

High Power Wideband Gyrotron Backward Wave Oscillator Operating towards the Terahertz Region


He, W., et al., High Power Wideband Gyrotron Backward Wave Oscillator Operating towards the Terahertz Region. Phys. Rev. Lett., 2013. 110(16): p. 165101.


http://www.ncbi.nlm.nih.gov/pubmed/23679610


Experimental results are presented of the first successful gyrotron backward wave oscillator (gyro-BWO) with continuous frequency tuning near the low-terahertz region. A helically corrugated interaction region was used to allow efficient interaction over a wide frequency band at the second harmonic of the electron cyclotron frequency without parasitic output. The gyro-BWO generated a maximum output power of 12 kW when driven by a 40 kV, 1.5 A, annular-shaped large-orbit electron beam and achieved a frequency tuning band of 88-102.5 GHz by adjusting the cavity magnetic field. The performance of the gyro-BWO is consistent with 3D particle-in-cell numerical simulations.

Chemical shift correlation at high MAS frequencies employing low-power symmetry-based mixing schemes
Chemical shift correlation at high MAS frequencies employing low-power symmetry-based mixing schemes Abstract An approach for conveniently implementing low-power CN n ν and RN n ν symmetry-based band-selective mixing sequences for generating homo- and heteronuclear chemical shift correlation NMR spectra of low γ nuclei in biological solids is demonstrated. Efficient magnetisation transfer characteristics are achieved by selecting appropriate symmetries requiring the application of basic RF elements of relatively long duration and numerically tailoring the RF field modulation profile...

Standard operating procedures for pre-analytical handling of blood and urine for metabolomic studies and biobanks
Standard operating procedures for pre-analytical handling of blood and urine for metabolomic studies and biobanks Abstract 1H NMR metabolic profiling of urine, serum and plasma has been used to monitor the impact of the pre-analytical steps on the sample quality and stability in order to propose standard operating procedures (SOPs) for deposition in biobanks. We analyzed the quality of serum and plasma samples as a function of the elapsed time (t = 0??4 h) between blood collection and processing and of the time from processing to freezing (up to 24 h). The stability of the urine...
