| 3 | The Use of JEM scopes with Leginon is still under development but here are some modification specific to them that we use. |
||
| 4 | |||
| 5 | h2. "image beam shift" on JEOL scopes is equivalent to "image shift" applied by the users on FEI instrument |
||
| 6 | |||
| 7 | Such movement should move feature in the view without induced movement of the beam. |
||
| 8 | |||
| 9 | h2. Some model has such a slower relax time in image shift in LOWMAG range that it is necessary not to access it in target adjustment. |
||
| 10 | |||
| 11 | An additional targeting/imaging step is added so that queued up exposure targets will not be adjusted using sq preset. |
||
| 12 | 2 | Anchi Cheng | Alternatively, custom lens program can be created to replace an unused MAG1 magnification that minimize the objective lens current change. See [[JEOL installation specifics]] |
