Figure 15
Absorbed dose around the electron beam axis and results of the demagnetization experiments. Full squares, full circles and full diamonds indicate the calculation results of the absorbed dose with the copper block at the upstream side, center and downstream side of the magnet, respectively. Open squares, open circles and open diamonds are the results obtained with the tantalum block. Squares with a cross, circles with a cross and diamonds with a cross are the results obtained without a block. Double circles are the experimental results with the copper block and the circles with a dot are the results obtained with the tantalum block (the values are given on the right-hand-side axis). The doses with the copper block owing to 2 GeV electrons indicate the calculation results for the configuration of the Pohang experiments. |
