Figure 4
Experimental results on the vacuum-pressure rise at the beam loading. Horizontal axes in (a), (b) and (c) represent the electron-beam energy, the total number of photons of synchrotron radiation, and the total power of synchrotron radiation, respectively. Stored current at a beam energy of 100 MeV was set to be 70 (○), 100 (×) and 120 mA (▵). |
