## Warning:
|
|
|
- visible light makes the vortex software (IOC) crash; always turn the vortex off before turning on the light or opening the windows; you will also need to restart the software.
|
|
|
- the vortex is sensitive to visible light so the lamp should be off and windows closed
|
|
|
- if you cycle power or turn on the light, you will need to restart the IOC (software).
|
|
|
- after turning on the vortex, wait 5 min for it to cool down
|
|
|
- always remove the vortex from the detectors when IOC is off (see below)

1. In jupyter:
|
|
|
|
|
|
```python
|
|
|
scanmca() # add vortex as a detector in the scan
|
|

```

2. set the Preamp gain to 2.7 and then back to 2.5.
|
|
|
2. press ![image](uploads/63aee19d1a96b28be8659638e7e8a838/image.png)
|
|
|
3. if there is no count or a very large DeadTime, change the Threshold to 1 and then back to 0.95; you may need to toggle the Preamp gain to 2.7 then back to 2.5 a few times, until you see counts when pressing ![image](uploads/4a2c9b1262a647258b61d4275d150336/image.png)
|
|
|
4. within the first few hour, the count sometimes drops to zero again: repeat step 2 and 3; once it stabilizes it seems to only rarely have issues afterward
