Minutes
Pavel went over his shielding and power deposition plots and we discussed the implementation of them into the design. The shielding layout we supplied to Pavel is acceptable with a 12" thick borated poly shield around the absorber going down close to the floor. There is no poly below the assembly and downstream and upstream can be thinner (6"). Nominally, we will put a 2" steel plate below the assembly close to the floor which will count as shielding, air caster support and borated poly support. We are in general agreement that the power deposition and associated temperatures in the 20% radiator nominal and narrow beam configurations are acceptable. There are still some questions on relative power absorption compared to the 10% radiator.
