The experimental hutch is considered a laboratory -- no food or drink allowed.  No one is allowed inside the hutch with the door closed, even if there is no x-ray beam in the ring.

Users should be aware that there is no collision protection on the equipment, only limit switches and software limits.  Operation of the detector or goniometer motors will not stop abruptly unless done so via the keyboard. 

When moving, the CCD detector poses a crush hazard with the goniometer. Do not stand between the goniometer and detector when the detector is in motion.

When the CCD detector is not in use, the metal faceplate should be installed on the front face of the detector.

Never touch the front face of the CCD detector.  It is very fragile.

Users should be careful around the beam stop since it can be easily broken or displaced if bumped.

The goniometer motor moves very fast.  Anyone with long hair or long sleeve shirts should take precautions when standing or mounting crystals so as not to get anything caught on the goniometer motor or in the kappa mounting assembly.

All light sources around the goniometer are operated via fiber optics.  These bulbs are very hot and could cause burns.  Avoid opening the light sources or touching the light source boxes.

All cameras have a fixed optical zoom.  Do not touch any camera lens or adjust the zoom.  If adjusted, the optical properties of the beamline will be off-axis resulting in a displacement of the sample or alignment of the x-ray beam.

Only operate end-station equipment via the computer screen.  Never touch equipment controls inside the hutch.

Hutch interlocking is a two step process.  Hit the green button beneath the flashing yellow light on the hutch wall, then proceed to the next station button.  After exiting the hutch stand away from the hutch door and hold the station close button lights above the button turn green.  After 20 seconds you may open the D-shutter to let x-rays into the hutch.  Note:  The hutch door does not contain a bumper guard and has the potential to injure you if any part of your body gets between the door and the side wall.  Keep hands and legs away from the door when closing.

Press the OPEN button on the hutch panel to re-enter the hutch.

If, when interlocking, you want to go back into the hutch, simply let the interlocking process time out.  A voice will eventually say "...search invalid".  When complete, simply re-start the interlocking process from the beginning.

If you unexpectedly find yourself inside a locked hutch (which should never happen!) press the EMERGENCY STOP button.  This will dump the x-ray beam in the ring and alert the authorities of your presence.  If this button is pushed in accidentally before starting the interlocking process, the flashing yellow lights will not be activated.  It will be necessary to pull out this button before the lights will be activated.  If the button is already pushed out, there is something else wrong and you will need to contact your host or a floor coordinator.

The gaseous nitrogen stream is at 100 K.  Users should not put their hands or fingers in the gaseous stream for more than a few seconds (when mounting samples).  Otherwise frostbite may occur.

All users handling liquid nitrogen should wear appropriate personal protection equipment (PPE), such as gloves and safety glasses.

1.  The liquid nitrogen dispenser is an open tap to the APS nitrogen dewar, which contains several hundred gallons of liquid nitrogen.

2.  Always use safety gloves and a face mask when operating the nitrogen dispenser.  An apron is also available for your protection. 

3.  Users operating the nitrogen dispenser must have closed toed shoes and long pants on.

4.  Operators are required to remain by the station until their dewars are full or until the handle to the nitrogen is turned off.  NO UN-ATTENDED OPERATION!

5.  Excess liquid nitrogen from storage dewars may be dumped into the sand box as long as the users are wearing the appropriate PPE equipment.

For robotic crystal mounting use Hampton Magnetic Cap, SPINE, SSRL, and ALS magnetic bases with either stainless or copper posts 18mm in length.

It has been found that crystals mounted using LithoLoopsTM are most rigid in the cold stream. If nylon loops are used please ensure that the stalk that attaches to the metal post is short and has been coated with epoxy to make it rigid.

• The black rubber cap should not be covering the nozzle of the detector.
• Measure emission spectra and energy scans from samples containing anomalously scattering elements and ions using HKL3000.

19BM beamline

• When the detector is not in use, the black rubber cap should be installed to cover the nozzle of the detector.
• If the detector is positioned too close to the sample, the kappa stage of the goniometer can collide with the nozzle of the detector and damage the detector.
• The front face of the nozzle consists of a thin window of beryllium, which is located directly in front of the silicon diode sensor under vacuum. Touching the window could cause it to break, damaging the detector.
