Policies & Trainingx-ray-diffraction

A guide for new users 

• The X-Ray Diffraction Laboratory of the Weizmann Institute is both a service and a user facility. Training is available upon request in order to gain the skills required to independently perform measurements. Training is done on Ultime III. 
• As a service, a new user should consult with the staff of the X-ray diffraction laboratory concerning the type of structural information that can be obtained for his/her particular sample, and also regarding how to prepare samples for XRD analysis.  The staff will perform the measurements and data analysis. 
• Non-Weizmann users can’t work independently and must contact staff regarding the process to receive a price quote. 

General Policies 

• Access to the lab is allowed only to authorized personnel. 
• All diffractometers are operated with radiation safety enclosures. 
• Ambient radiation is monitored by the WIS safety unit and the Nahal Sorek laboratory. 
• All independent users must pass the WIS safety unit training course on general and radiation safety. 
• No food or beverages are permitted near the diffractometers or workstations. 
• Changing equipment alignment or lab workstation configuration is strictly forbidden. If any problems arise, the user must request help from the X-ray laboratory staff. 
• Upon completion of XRD measurements, samples must be removed from the sample holder and the sample preparation counter cleaned prior to the arrival of the next user. 

Facility Schedule (maintenance) 

• Routine maintenance is performed as needed. Shutdown time will be scheduled when necessary, but whenever possible, users will be given advance notice.
