Target & HornsA.K.Ichikawa

• Fluxes were distributed. W/ BNL-type and J-PARC type.

• Target cooling test

• Comparison of various carbons

• Energy deposit on 1st horn

• Serious stress analysis will start soon for both target and 1st horn.

• Further tuning of the horns is on going, but no better solution was found yet.

• Load test will start w/ mini-1st horn.
