ACCESS & TRAINING
The MIC X-ray facility is available to the entire UCLA community. All users must have a 6-digit chemistry recharge account prior to using our facility. If you are outside the department of Chemistry and Biochemistry, please request an account number (Application Form).
All users are required to undergo training before they are authorized to use the x-ray instruments to perform data collection independently. The training consists of:
a. Laboratory Safety Fundamental Concepts (LSFC)Training:
This training session must be completed prior to conducting any work in a laboratory setting. For registration and training information, please see the UCLA Department of Environment, Health & Safety (EH&S) website.
b. Radiation Safety Training:
This training session is also provided by the UCLA EH&S. For registration and training information, please see the UCLA EH&S website. You must complete online training course for radiation safety for users of radiation-producing machines. For further information, please read the radiation safety manual.
c. Instrument Specific Training:
After completing both LSFC and Radiation Safety Training sessions, please contact Saeed Khan, Ph.D. for training on a specific X-ray diffractometer. This one-on-one training session covers radiation safety features of the instrument as well as data collection and analysis procedures. In general, after this training, the users of the Powder Diffractometer should be able to operate the instrument according to the documented procedure without supervision. For single crystal diffractometers more than one session may be required before a person is certified to use the diffractometer
Scheduling and Instrument Reservations
All Reservations for single-crystal and powder X-ray diffractometers are made through our online reservation website. If your sample is unstable and you need to arrange for special circumstances, please contact Saeed Khan.
You must log onto each instrument through the LinRL computer in the X-Ray lab
Please download the following files for direction on how to use our web reservation system, & LinRL
For information regarding our instrument rates, please contact Saeed Khan directly.
Due to serious health hazards associated with exposure to radiation, the X-ray diffractometer have number of safety mechanisms to prevent such occurrences. All our diffractometer are in radiation shielding enclosure interlocked with x-ray shutters. They are also equipped with fail-safe warning lights for the status of x-ray generator and shutters. Users must not disable, alter, modify or bypass any safety interlocks associated with X-ray equipment. For a review on radiation safety, please see the Radiation Safety Manual posted on the EH&S website.
Only trained staff members are authorized to perform maintenance on X-ray equipment.
Radiation emitted from the diffractometer is intense, penetrating and dangerous. A hand held radiation monitor is available for your use---Use it.
Proper attire (long pants and closed-toed shoes) must be worn at all times when in the lab. Please be aware that proper PPE is the responsibility of the individual user.
All samples must be prepared only in the designated areas.
Do NOT store your samples in the diffractometer enclosures. Only properly labeled samples my be stored in the sample-prep designated areas.
All the sample holders for powder diffractometers are the property of the X-ray diffraction lab and must be cleaned and left in the lab after use. Please do NOT walk away with our sample holders.
If you are wearing gloves for sample prep, please remove your gloves before operating computers!
Please observe all posted signs in the laboratory. When in doubt ask questions and report problems immediately.
No food or drink is allowed in the lab at any time.
