Instructions and Rules regarding the SMXF Instrument Time Request System

 

 

Instructions:

 

  1. Access the SMXF Instrument Time Request System (SITRS) at http://crystals.ucsd.edu/scheduling/.
  2. Use your own login and password to enter SITRS.
  3. Sign up for a time and date you would like to begin your experiment by clicking on an open slot for an instrument.
  4. Request only 1 hour of time to begin with (regardless of your experiment to screen your sample) by clicking on the same time slot clicked in the previous step.
  5. Click the Sign-up button and your request will be submitted.  Keep in mind that this is only a request and your start time may be shifted by upwards of 24 hours depending on the ending time of the previous experiment, required instrument maintenance, etc.
  6. Once your request is approved and scheduled you will receive an automated e-mail from SITRS.  You will also receive an automated e-mail if any changes are made to your request to keep you informed of when the instrument will be available for your experiment.
  7. When it’s your turn, screen your crystal and begin your data collection.  Once the data collection is in progress, log back in to SITRS and update the end time for your block according to the length of your experiment.  Overnight data collections that end on weekdays should be setup to end by 8:00 AM the next day.  If your screening was unsuccessful or if you were only performing a unit cell determination, you do not have to update your end time on SITRS.  Data collections longer than 24 hours will be assessed a LN2 surcharge of $50 for each 12 hour period beyond the initial 24 hours.
  8. On weekends, it is your responsibility to turn off the low temperature device if no one is scheduled after you.  Always leave the low temperature device on during the week.

 

Who can use this system?

 

UCSD Department of Chemistry and Biochemistry graduate students who have successfully completed and passed Prof. Rheingold’s Practical X-ray Crystallography course are eligible to obtain their own login and password for the SMXF Instrument Time Request System (SITRS).  Post-docs and other faculty who have demonstrated their proficiency in X-ray crystallography and use of the instrumentation may also obtain their own login and password for SITRS.  Undergraduates may not obtain their own login and password as they are not permitted to operate any diffractometer with out the direct supervision of a trained graduate student, post-doc or faculty member.

 

How do I obtain a login and password?

 

Please send an e-mail to Dr. DiPasquale at adipasqu@ucsd.edu requesting access to SITRS.
