6 mm Cu Radiator/Dump

Realistic Thermal Analysis:

Updated spreadsheet with energy deposition at 9.5 and 5 MeV beam energies (first 2 sheets have data binned in 1mm intervals both in Z direction and radially, third sheet has 5 MeV data in 0.5mm bins). All deposited power adds up to about 85% of the beam power. These models assume Gaussian beam with sigma=0.2mm (G. Kharashvili): media:radiator_power.xlsx
Analysis results (F. Fors): media:Bubble_Chamber_Thermal_FF082015.pdf media:Bubble_Chamber_Thermal_FF082015.pptx

Drawing: media:JL0015733 CU RADIATOR WINDOW ASSY.pdf
Thermal Analysis: media:ThermalAna_IDL5D01.pdf
Approved to run up to 10 µA or 100 W (September 2014)
LCW flow to radiator/dump was measured with:

a flow-meter and was found to be 0.9 GPM
a bucket and was found to be 2.0 GPM

LCW temperature is 40°C

The electron beam hitting the radiator will be roughly 0.2 mm diameter. We will allow for 5 mm diameter sweet spot. Using beam position monitors we will know the beam position on the radiator to about 1 mm.

This 5 mm diameter and a 10 mm diameter in the center of the bubble chamber will define a cone. This way we can determine the size of the holes in the collimator. This cone extend all the way to the photon dump.

The table where the radiator and collimator sit will be made of Al and the frame that hold the collimator will be made of Al, too.

Cu Radiator: media:Bubble_Cu_Radiator.pdf
Cu Collimator: media:Bubble_Cu_Collimator.pdf
Al Photon Dump: media:Al_Photon_Dump.pdf

Questions:

Is the assumption about the cone fine. Do want the 10 mm diameter be at the center of the bubble chamber or at the end of the chamber entrance collimator.
Is the 5mm diameter what we want to use?
Is the size of the photon dump reasonable? Do we need the hole in the photon dump or we can be fine with just a block of Al. Does this whole service any purpose? I thought of it to try to contain any back scattered electrons. Can Argonne make the photon dump?
