Khutoryan, E.M., et al., Stabilization of Gyrotron Frequency by PID Feedback Control on the Acceleration Voltage. J Infrared Milli Terahz Waves, 2015. 36(12): p. 1157-1163.
The results of frequency stabilization by proportional-integral-derivative (PID) feedback control of acceleration voltage in the 460-GHz Gyrotron FU CW GVI (the official name in Osaka University is Gyrotron FU CW GOI) are presented. The experiment was organized on the basis of the frequency modulation by modulation of acceleration voltage of beam electrons. The frequency stabilization during 10 h experiment was better than 10-6, which is compared with the results of the frequency deviation in free-running gyrotron operation.

Abstract
Ion transport through nanochannels is of fundamental importance in voltage-gated protein ion channels and energy storage devices. Direct microscopic observations are critical for understanding the intricacy of ionic processes in nanoconfinement. Here we...

Authors: Sem DS, Pellecchia M
The field of NMR spectroscopy has grown beyond expectations from the first historic observation of nuclear magnetic resonance in 1946 by Bloch and Purcell, to the first generation of protein structures 20 years ago, to the present where NMR structures now represent 15 to 20% of those submitted to the Protein Data Bank (PDB). However, the applications of NMR go far...
