Description
Resonant Schottky pick-up cavities are sensitive beam monitors. They are indispensable
for the beam diagnostics in storage rings. Apart from their applications in the
measurements of beam parameters, they can be used in non-destructive in-ring decay
studies of radioactive ion beams [1]. In addition, position sensitive Schottky pick-up
cavities enhance precision in the isochronous mass measurement technique.
The goal of this work is to construct and test such a position sensitive cavity (Schottky
detector) based on previous theoretical calculations and simulations. These cavities
will allow measurement of a particle‘s horizontal position using the monopole mode
in a non-circular(elliptic) geometry [2]. This information can be further analyzed to
increase the performance in isochronous mass spectrometry [3-4]. A brief description
of the detector and its application in mass and lifetime measurements will be provided
in this contribution.
Keywords: storage rings, Shottky detector, ion beam measurement
