Taking an image
1. Choose which camera to use by plugging its cable into the USB box.2. Turn on the 12V DC power (shown in the picture below), its indicator will turn yellow. It takes about 15 minutes for the CCD cooling down to about -30 Celsius (but you do not need to wait this long, you may start immediately). Remember, you must turn off the camera control software on bnmrpc.triumf.ca before you switching the cables.
3. If you need more light turn on the LEDs. Remember to turn it off before you continue your experiment.
4. Turn on the camera control software on BNMRPC by left clicking the 500MX icon on the desktop. If it is already on and can't find the camera, you have to reboot the computer.
5. Choose the right scale for BNMR camera or BNQR camera. 6. Check exposure time before a shot. Normally 0.1 second with LED and 30 seconds without LED.
7. To get an image, click the START button. If the shot is not clear, choose stretch line from the Option menu of the software. If it is not improved, adjust the exposure time.
8. Moving the mouse to the position of interest, e.g.the center of the beam spot or sample position, the software will show the coordinates of the position. You can record up to 11 coordinates for later reference.
9. If needed, save the shot to the BNMRIMAGE folder on the desktop for later reference, you may need a new subfolder for every experiment.
10. Need a new image repeat steps 7,8,9.
11. Make sure the LED is off before you continue your experiment.
