The closed orbit was measured at F1 and F5 with each probe in three positions.

F1: 200, 150, 100 mm

F5: 300, 250, 200 mm

where the offset from zero radius is 4705.5mm in the case of F1 and 4708mm in the case of F5.

Capture efficiency measurement with script. Several patterns are tried

1. constant phis=20 deg for 0.5 ms, linearly decreases phis from 20 to 0 deg for 0.3 ms and keep energy until 25 ms after injection.

2. constant phis=20 deg for 0.05 ms, linearly decreases phis from 20 to 0 deg for 0.3 ms and keep energy until 25 ms after injection.

3. From the start, linearly decreases phis from 20 to 0 deg for 0.3 ms and keep energy until 25 ms after injection.

4. From the start, linearly decreases phis from 10 to 0 deg for 0.3 ms.
