This document provides updates on the TOWER thermal simulations discussed in the TT-PET Meeting on April 28th, 2016. The simulations include the effect of replacing SiO2 with a flexible material, cooling pipes, heat dissipation areas, and the use of water cooling. Future outlooks and proposals for improving the design are also discussed.

Outlooks… • Estimate by hand calculation the h coeffgiven the velocity thru the channels… with Water. • Estimate the Delta T between Inlet and Outlet…so far this is neglected in FEA! • Propose some overall manifolding design …to limit the above delta T (Inlet/Outlet) • Why not trying with a first aluminum 3D printed cooling block?
