Cooling studies for the Outer Barrel of ALICE3 — •Laszlo Varga for the ALICE Germany collaboration — Technische Universität München, Munich, Germany

In the upcoming ALICE3 experiment a completely new large area tracker fully based on MAPS technology will be installed. The largest area will be covered by the Outer Tracker (OT) which consists of four large barrels around mid rapidity and discs in forward and backward direction. The barrel part will be built from a stave structure approximating a cylindrical geometry. The layout of these staves and especially the cooling of 33 square meters of active surface will have a strong influence on the total design of the device. In this contribution, possible cooling methods for the OT barrel layers will be discussed. Large scale simulations have been carried out using the COMSOL Multiphysics finite element tool. We will discuss different concepts which have to balance strict constraints in temperature, material budget and complexity of the integration.
