beam overlap with t-scrapers |
|
|
When testing the overlap between laser and ion beam we observed the following positions:
|
motor | ion beam position (mm) from outside | ion beam position (mm) from inside
| |
GECEDS1VU | 0 | 6.5
| |
GECEDS1HA | -22.5 | -13.5
| |
GECEDS2VU | 1 | 8.5
| |
GECEDS2HA | -20.5 | -10
|
Note: To move GECEDS1VU the corresponding horizontal drive (GECEDS1HA) has to be at 2 mm. |
