Abstract :
This paper addresses the evolution, design, analysis and development of a novel approach for stopping the proton beam at a 7.5 MeV power level. During commissioning of the Spallation Neutron Source (SNS) injector, the first Drift Tube Linac (DTL) tank will be installed, and in the place of the second DTL tank a diagnostic plate assembly will be inserted and the beam thoroughly tested. The beam will be tested at full power (36 mA, 1 ms, 60 Hz), so a beam stop is being designed to handle the thermal and structural stresses and minimize neutron production. The beam stop is assumed to be a cone configuration with radius of 10 cm base and slope of 3.5 cm/cm. It will be made of Nickel 200 that is 2 mm thick
