Introduction

At the future ISOL@MYRRHA facility at SCK CEN, short lived radioactive isotopes will be produced by proton induced fission and spallation of a stable target material. In order to assess the feasability of an experiments, the yield of the radioactive isotope (the production rate per second) is an important parameter.

A "yield station" is an experimental setup optimized to measure the production rate of a certain radioactive isotope. Such yield stations are already available at other ISOL facilities such as ISOLDE (CERN, isolde.web.cern.ch/) or TRIUMF (https://www.triumf.ca/). It consists of a moveable tape, on which the radioactive isotope is implanted. The implantation point is surrounded by plastic scintillators (to detect beta particles), alfa detectors and a gamma detector.

The optimal position of these detectors depends on the design of the yield station. The purpose of this project is to define a design, based on existing designs at other facilities and to simulate it in standard particle tracking codes such as GEANT4 (https://geant4.web.cern.ch/). A few key isotopes will be used to assess the best configuration of detectors around the implantation point.
