Figure 8
Beam lifetime of MIRRORCLE-6FIR measured using a cooled Si bolometer at 100 mA injection beam current and 15 Hz repetition rate. The observed 800 ms lifetime is quite large for such a low-energy storage ring, but the expected Touscheck lifetime is almost 1 min. The lifetime is limited by gas scattering owing to a poor vacuum pressure of 1.4 × 10−4 Pa. |
