Welcome to the University of Colorado School of Medicine on the Anschutz Medical Campus. We are a Top Ten Medical School in primary care, pediatrics, family medicine and rural medicine, and offer physical therapy and physician assistant programs.

Quick Start for Raxis 1 (the right port, all steps are labeled in GREEN)

1. Turn on shut off valve if left port is not in use and set the regulator to 25psi and let run for 5 mins
2. Turn on the power for the X-stream system control box.
3. Turn on the power for the helium compressor.
4. Turn on the helium tank for the X-ray optics.
5. Turn on the crystal monitor.
6. Turn on the pump for the area detector.
7. (Skip steps 7 and 8 if the left port is in use and the generator is already at full power.) Press the leftmost “ON” switch on the X-ray panel.
8. Start the “Xg” software on Raxis I control computer. Go to “Task”, click “Warm-up Used Filaments”.
9. Close both doors to the generator room (Rm 1301) and turn on the Mag lock (on the pillar).
10. Turn both safety interlocks (on the pillar) to “normal” positions.
11. Sign in the logbook noting filament hours, N2 volume, and vacuum.
12. Start “Crystal Clear” and you are ready to do your experiments.

Turn off Raxis 1

1. (Skip this step and go to step 2 if the left port still needs the generator.) If nobody signed up to use Raxis1 within the next 48 hours, go to “Xg”, under “Task”, click “Shut off X-rays” (label 9).
2. Turn off pump for the area detector (label 6).
3. Turn off the crystal monitor (label 5).
4. Turn off the helium tank (label 4).
5. Turn off the helium compressor (label 3).
6. Turn off the X-stream control box (label 2).
7. Turn off the regulator (label 1) for in house N2 and if left port is not in use turn off shut off valve.
8. Sign out in the logbook noting filament hours, N2 volume, and vacuum (label 11).

Quick Start for Raxis 2 (the left port, all steps are labeled in RED)

13. Turn on shut off valve if right port is not in use and set the regulator to 25psi and let run for 5 mins
14. Turn on the power for the X-stream system control box.
15. Turn on the power for the helium compressor.
16. Turn on the helium tank for the X-ray optics.
17. Turn on the crystal monitor.
18. Turn on the pump for the area detector.
19. (Skip steps 7 and 8 if the right port is in use and the generator is already at full power.) Press the leftmost “ON” switch on the X-ray panel.
20. Start the “Xg” software. Go to “Task”, click “Warm-up Used Filaments”.
21. Close both doors to the generator room (Rm 1301) and turn on the Mag lock (on the pillar).
22. Turn both safety interlocks (on the pillar) to “normal” positions.
23. Sign in the logbook noting filament hours, N2 volume, and vacuum..
24. Start “Crystal Clear” and you are ready to do your experiments.

Turn off Raxis 2

9. (Skip this step and go to step 2 if the right port still needs the generator.) If nobody signed up to use Raxis1 within the next 48 hours, go to “Xg”, under “Task”, click “Shut off X-rays” (label 8).
10. Turn off pump for the area detector (label 6).
11. Turn off the crystal monitor (label 5).
12. Turn off the helium tank (label 4).
13. Turn off the helium compressor (label 3).
14. Turn off the X-stream control box (label 2).
15. Turn off regulator (label 1) for in house N2 and if right port is not in use turn off shut off valve.
16. Sign out in the logbook noting filament hours, N2 volume, and vacuum (label 11).

Radiation safety rules and the use of safety interlock

Before you go into the x-ray enclosure,

1. Check that the safety interlock on your side is on the “interlock” position.
2. Turn the safety interlock on your opposite side to the “override position.

When you come out of the x-ray enclosure,
Make sure that both safety interlocks are on the interlock positions.

General radiation safety rules:

1. Always wear your body badge and ring badge when you need to go in the x-ray enclosure.
2. Make sure all exposures on your port are completed on the computer before you go in the x-ray enclosure.
3. Make sure the red shutter light on top of the shutter and the yellow shutter light on the warning tree are off before you mount/dismount your crystals. It is always a good idea to keep an eye on these lights when you work close to the direct beam.
4. Never place any part of your body in the direct beam.
5. Check the radiation with Guiger Counter whenever you are in doubt.

Turn down for Raxis 1 (the right port, all steps are labeled in GREEN)

1. If you or another user is signed up to use Raxis 1 or 2 within the next 48 hours and if they or you do not want to be charged for down time go to “Xg”, under “Task” and click “Turn Down X-rays” (label 8).
