BL 2-3 Microscan Troubleshooting

Microscan video feed appears unresponsive


This can happen for two reasons: (1) The video feed is frozen so you're moving but it doesn't look like it or (2) The stage motors are disabled.


Frozen video feed:

First, close and reopen microscan. Click on F0 to get the crosshairs back. If you get window that says something about Windows checking for a solution or something just cancel those to get microscan to close.

If this doesn't work, restart the sample camera. There is a “camera server” running on another computer that controls the sample camera video feed: 

1. On the beamline computer, close “microscan” if it is running.
2. Go to the Remote Desktop application. This computer should already be logged in (IP address:

3. Look for a program named “CameraServer” running. If CameraServer is NOT running, start it again from the desktop shortcut. If it is running, close and restart it. 

4. If CameraServer will not restart, then on the main computer go to PDU and turn off "Sample Camera" and then turn it back on.

5. Repeat step 3
6. Once the program is running again, go back to the beamline computer and start “microscan.” The program should restart properly. Press the “F0” button on the right side of the video screen: this will re-load the display and camera parameters. Crosshairs should now appear on the screen.
Note: If there is no sample on the beamline, or if it is dark, the black crosshairs might not show up very well against the background. Change the crosshair color by selecting “Video” and “Crosshair Color”…change to Red, Blue, Green or Yellow.

Stage motors are disabled:

(1) Go to the browser window that is logged onto Newport (

(2) Does x.x, y.y or z.z say "enable"? If so, press the button saying "enable"

(3) Does x.x, y.y or z.z say "initialize" If so, DO NOT PRESS ANYTHING. Contact beamline staff.

Microscan displays don't show anything

The displays often freeze, especially after several maps have been collected. Close and reopen microscan.

If you the displays still show nothing, check whether you see data when you open the file in SMAK. If you don't, contact beamline staff

MONO Shows an error

Sometimes the ICS server (the server that interconnects all the beam line electronics) disconnects. This sometimes presents itself as an error (#ERROR#) in uXAS and/or MICROSCAN (where the red box is located in the following images).

If you are physically present at the beamline, you can restart ICS. If you are remote, contact beamline staff

1. Close DataServer, microXAS, and microscan

2. Go to the Linux computer, which is the monitor directly to the left of the beamline PC.
3.Open a terminal window.
4. In the terminal type “ics_cpc” (without the quotes) and then press enter.
5. Then type “4” enter.

6. Agree to “default” by pressing enter .
7. Type “Y” enter to select yes you really want to restart.













8. You may wait up to a minute or so until ICS shuts down.

9. Now type “3”.
10. Agree to “default” by pressing enter.












11. Several seconds should elapse and ICS will be restarted.
12. Restart DataServer, microXAS, and microscan
