Study on ambient and cryogenic grinding was performed to test the novelty of cryogenic grinding and pin point the drawbacks of ambient grinding. Comparative study had shown that ambient grinding need more power (8.92%) and specific energy (14.5%) than cryogenic grinding. Particle size analysis had shown that cryogenic grinding produced coarser particles. Comparative study of energy law constant...

The slow-wave cyclotron-resonance master ~CRM! oscillator experiment presented in this paper produces output signals that correspond to normal and anomalous Doppler shifts. The table-top low-voltage (,10 kV! CRM device consists of a double stripline waveguide. The metal strips are loaded by dielectric slabs; thus the waveguide supports slow waves with different phase velocities in odd and even ...

A conceptually simple method for linac tuning has been tested on the 200 MeV drift-tube linear accelerator at Fermilab. The phase of a beam-induced signal in a stripline detector is measured as tank phase is scanned over approximately 360 degrees. The stripline detector is downstream of the tuned tank. The resulting phase-scan curves have unique signatures that depend upon only a few critical p...

A tunable fluid-loaded free-electron laser ~FEL! oscillator is demonstrated. This FEL-type experiment employs low-energy electrons, down to 0.4 keV. Therefore, it interacts with extremely long radio waves, in the VHF range (l.1 m). The device consists of a folded-foil planar wiggler (lW54 cm), and a double-stripline cavity. The variable dielectric loading is implemented by distilled water in gl...

Electromagnetic compatibility (EMC) analysis of high-speed circuits is mandatory due to the rapid increase in operating frequencies, RF interference and PCB layout density. Radiated emission and immunity tests of electronic circuits and ICs are an important part of the overall EMC analysis and they have become a growing concern in prediction of an electronic system reliability. These tests are ...

A fast stripline beam kicker is used to dynamically switch a high current electron beam between two beamlines. The transverse dipole impedance of a stripline beam kicker has been previously determined from a simple transmission line model of the structure [1]. This model did not include effects due to the long axial slots along the structure as well as the cavities and coaxial feed transition s...

In this paper, a new de-embedding technique with Look-Up Table (LUT) is proposed for accurate and efficient characterization of interconnects, particularly printed circuit board (PCB) transmission lines including microstrip and stripline. LUT is pre-created to cover various fixture effects including the reference structures inside and/or outside test printed circuit boards (PCBs). The pre-estab...
