The remote operation of NMRFAM spectrometers has become increasingly popular. A user sends a sample to the facility; a NMRFAM staff member adjusts the temperature, places the sample in the magnet, and tunes and matches the probe. The remote user is notified that the spectrometer is ready and the user proceeds with the experiment. At the end of the experiment, the sample is removed from the magnet, stored, or shipped back as desired. In order to streamline this process, we have developed a procedure that should be followed to ensure efficient use of spectrometer and staff time.
Instructions for remote users (1-4) and collaborators (1-3)
1. Submit a time request
Use Sundial at www.sesame.wisc.eduÂ to submit a time request. Contact Rita Hannah (firstname.lastname@example.org, 608-262-3173) for assistance. Scientific questions should be forwarded to Milo Westler (email@example.com). Make sure that your time request states that you will be running remotely. Time requests are due on the 19th of each month (for spectrometer time during the next calendar month).
2. Make arrangements to send the sample
When your time request is scheduled you will receive notification that the new schedule is available to be viewed. At this point you should contact Rita Hannah with information about your sample:
- Shipping date and carrier
- Storage conditions at NMRFAM
- How to return it after the run. Please provide a prepaid, filled-out shipping label from your prefered shipping agent (FedEx, UPS). Our address is:
University of Wisconsin-Madison
433 Babcock Dr.
Madison, WI 53706-1544
3. Contact your on-site operator or collaborator
You will be assigned a contact at NMRFAM for this run. Please e-mail your contact person 2-3 days prior to the scheduled time with the specifics about the experiments.
Provide information about:
- What spectrometer are you using?
- When does the time start?
- When does the time end?
- To what temperature should the spectrometer be set?
- What is the salt concentration in the sample and what nuclei will be used in the experiment (in order to tune and match the channels)?
- What should be done with the sample after it comes out of the spectrometer?
- Temporary storage conditions
- Return instructions (immediate, upon request).
- Special handling instructions.
4. Run the experiment
Interactive internet access to the NMRFAM spectrometer computers requires the use of the SSH protocol (port 22). NMRFAM no longer accepts telnet or rlogin connections (port 23). Please make sure that your spectrometer login is ready and operational prior to the scheduled time. Note: the login for the NMRFAM spectrometer is distinct from your Sundial account.
For remote operation of the acquisition software VNC client software is required. This eliminates problems associated with interrupted internet connections during experiments. The VNC client application software is available for free for most computer platforms. Check the links below for more on the VNC client software or google VNC.
