Status report and first results of the microwave LSW experiment at CERN
M. Betz, F. Caspers, M. Gasior +1
To detect or exclude the existence of hidden sector photons or axion like particles, a table-top "microwaves shining through the wall" experiment has been set up at CERN. An overvi…
Novel types of anti-ecloud surfaces
I. Montero, L. Aguilera, M. E. Dávila +9
In high power RF devices for space, secondary electron emission appears as the main parameter governing the multipactor effect and as well as the e-cloud in large accelerators. Cri…
Microwave spectroscopic study of the hyperfine structure of antiprotonic helium-3
Susanne Friedreich, Daniel Barna, Fritz Caspers +11
In this work we describe the latest results for the measurements of the hyperfine structure of antiprotonic helium-3. Two out of four measurable super-super-hyperfine SSHF transiti…
Status report of the CERN light shining through the wall experiment with microwave axions and related aspects
M. Betz, F. Caspers, M. Gasior +1
One way to proof or exclude the existence of axion like particles is a microwave light shining through the wall experiment. In this publication we will emphasize on the engineering…
RF engineering basic concepts: the Smith chart
F. Caspers
The Smith chart is a very valuable and important tool that facilitates interpretation of S-parameter measurements. This paper will give a brief overview on why and more importantly…
RF measurements I: signal receiving techniques
F. Caspers
For the characterization of components, systems and signals in the RF and microwave range, several dedicated instruments are in use. In this paper the fundamentals of the RF-signal…
