An angular-selective electron source for the KATRIN experiment
M. Beck, K. Bokeloh, H. Hein +10
The KATRIN experiment is going to search for the average mass of the electron antineutrino with a sensitivity of 0.2 eV/c2. It uses a retardation spectrometer of MAC-E filter type…
Classical calculation of relativistic frequency-shifts in an ideal Penning trap
Jochen Ketter, Tommi Eronen, Martin Höcker +3
The ideal Penning trap consists of a uniform magnetic field and an electrostatic quadrupole potential. In the classical low-energy limit, the three characteristic eigenfrequencies…
First-order perturbative calculation of the frequency-shifts caused by static cylindrically-symmetric electric and magnetic imperfections of a Penning trap
Jochen Ketter, Tommi Eronen, Martin Höcker +2
The ideal Penning trap consists of a uniform magnetic field and an electrostatic quadrupole potential. Cylindrically-symmetric deviations thereof are parametrized by the coefficien…
A UV LED-based fast-pulsed photoelectron source for time-of-flight studies
K. Valerius, M. Beck, H. Arlinghaus +7
We report on spectroscopy and time-of-flight measurements using an 18 keV fast-pulsed photoelectron source of adjustable intensity, ranging from single photoelectrons per pulse to…
Nonlinear ac susceptibility studies of high- rings: Influence of the structuring method and determination of the flux creep exponent
S. Streubel, F. Mrowka, M. Wurlitzer +2
We have studied the influence of the patterning procedure on the critical current density of high- YBaCuO thin rings using the nonlinear ac susceptibility meth…
