Feasibility Study on a Backward Angle Sampling Calorimeter for the P2 Experiment at MESA — Òscar Andújar Sabán¹, Ning Cao¹, Luigi Capozza¹, •Jonas Geisbüsch¹, Ravi Gowdru Manjunata¹, Frank Maas^1,2,3, Antoine Martinet¹, Oliver Noll^1,2, Paul Schöner¹, Christoph Rosner¹, Pierre Vijayan¹, and Sahra Wolff¹ — ¹Helmholtz-Institut Mainz, Mainz, Germany — ²Institute of Nuclear Physics, Mainz, Germany — ³PRISMA+ Cluster of Excellence, Mainz, Germany

A sampling calorimeter with SIPM read-out for the detection of high energy particles is under development. Such a calorimeter can be well suited for many experiment applications where space limitations apply. The main focus is on choosing the right material, as well as the right arrangement of active and passive material. Different mechanical options will be explored. The detector prototype design will be prepared by doing detector response simulations to ensure a high energy resolution, as well as a high spatial resolution. A possible application for such a calorimeter is the P2 experiment at the upcoming MESA accelerator in Mainz. The talk will give an update on the progress of this project.
