Novel Diamond-based Detector for Beam Characterization 

Trainee: Miha Cerv
Supervisor: Erich Griesmayer

Diamond has been used for many applications in beam instrumentation. The Fellow at CIVIDEC studied the use of Ultra-thin Diamond Detectors as beam position and profile monitors in low energy antiproton beam lines. He carried out R&D into a new type of beam monitor which was based on diamond membranes with 500μm-thickness on the one hand and pixelized diamond electrode structures on the other. Initial simulations have already indicated a position resolution in the sub-μm range and at extremely fast counting rates in the range of Gigahertz, fully exploiting the advances of diamond as radiation sensor material. The project also focused on the development of hardware for real-time signal analysis of the measurement.

In collaboration with another AVA Fellow, a developed diamond detector was exposed to the incoming low-energy antiproton beam during measurements at the AEgIS experiment. The detector built shows great promise for detection and characterisation of low energy beams and ongoing studies will focus onto the detailed performance of this new monitor type.



Beam Diagnostics and Particle Detection

Trainee: Vassilis Vrettakos
Supervisor: Erich Griesmayer

This project investigated the application of a diamond membrane detector for antimatter research. The Fellow analysied experimental data taken during beam tests with a prototype detector in 2017-2018 at the AEGIS experiment at CERN. 

As part of this work, the Fellow designed an ultra-thin, vacuum compatible diamond membrane detector and the related front-end electronics for antimatter research.
