The field of dynamic nuclear polarization has undergone tremendous developments and
diversification since its inception more than 6 decades ago. In this review we provide an in …

Bibliometric data set the scene by illustrating the growth of terahertz work and the present
interest in terahertz science and technology. After locating terahertz sources within the …

A 263 GHz continuous-wave (CW) gyrotron was developed at the IAP RAS for future
applications as a microwave power source in Dynamic Nuclear Polarization/Nuclear …

Advances in dynamic nuclear polarization (DNP) instrumentation and methodology have
been key factors in the recent growth of solid-state DNP NMR applications. We review the …

We describe new versions of high-harmonic gyrotrons with axis-encircling electron beams
developed on the basis of two (80-keV pulsed and 30-keV continuous wave) experimental …

We review the development of radiation sources and present the most notable examples of
the use of gyrotrons in spectroscopy and material diagnostics. We describe the main …

Nowadays, gyrotrons are used in numerous and diverse fields of research and technology.
Their most prominent application is to electron cyclotron resonance plasma heating and …

Sensitivity enhancement of MAS NMR using dynamic nuclear polarization (DNP) is gaining
importance at moderate fields (B 0< 9 T) and temperatures (T> 90 K) with potential …

We describe a frequency-agile gyrotron which can generate frequency-chirped microwave
pulses. An arbitrary waveform generator (AWG) within the NMR spectrometer controls the …
