Characterization and Simulation of the H6 Secondary Beamline for Beam Spot Reduction

In this work, the current configuration and limitations of the H6 Secondary Beamline in the Experimental North Area (EHN1) are discussed. Modifications to unused space in user zone PPE146 are proposed to decrease the beam spot downstream and simulations are made to model the proposed solution and predict the spot size of the beam. These predictions were compared and validated with measurements of the beam taken in early August 2024.
