Energy deposition and its effects on the E/sup +/ capture section at Sector 20

PDF Version Also Available for Download.

Description

The temperature profile and resulting stresses and strains of the capture section (positron source accelerator section) at Sector 20 were investigated. The Electron-Gamma Shower program, Version 4 (EGS4) was used to determine energy deposition. For a 31.68 kW, 33 GeV electron beam, the rate of energy deposition in the first accelerator disk downstream from the 90/10 tantalum-tungsten positron target was determined to be 0.56 kW. The calculated resulting temperature difference from the inner disk diameter to the outer disk diameter is 49.4/sup 0/F. The inner diameter could then reach a temperature of 169.5/sup 0/F. The maximum stress produced in this ... continued below

The maximum stress produced in this first disk would be a compressive stress of 4374 psi, also at the inner diameter.
