Description

In J-PARC Main Ring (MR), the number of shots during beam tuning with a high intensity beam is limited due to shortage of beam dump heat capacity. With the J-PARC MR upgrade for higher intensity, a new beam dump is planned to ease this limitation. The heat capacity of new beam dump is 30 kW. The new beam dump is designed to add the dump core and cooling mechanism into the existing beam dump. It will be planned air-cooled and dump core is made of copper. In this study, Computer Aided Engineering (CAE) analysis was conducted for two models of new beam dump core. As the results of calculation, it was evaluated that the model having cooling fins and legs was suited for dump core. The required cooling air flow late was calculated to be more than 0.52 m3/s.
