P42 T4/XTAX transmission efficiency - FLUKA

The studies reported here are part of the ECN3 Beam Delivery Task Force’s mandate. Designated by the PBC Study Group, the primary objective of the Task Force is to assess the technical feasibility of increasing the proton beam intensity transported along the P42 line to the ECN3 cavern of the North Area in order to satisfy the demands of a set of PBC experimental physics proposals. The purpose of this note is to present the findings on the transmission efficiency from the T4 target to the associated Target Attenuator eXperimental areas (XTAX), along the P42 line. Different Beam Intercepting Devices (BIDs) configurations have been investigated using realistic beam distributions, considering both the requirements of the proposed experiments and the North Area’s characteristic proton sharing scenario.
