Adding and Editing Probes

Facility staff can add or edit probes through the Facility Dashboard. Each probe entry is divided into several sections: Basic Information, Operating Temperature Range, and Channels. Channels can include individual nuclei or broadband frequency ranges.

Modal popup for adding and editing probes

Basic Information

Field	Description	Required
Status	Select: Operational, Under Repair, or Decommissioned.	Yes
Type	Select: Solution or Solid State.	Yes
Vendor	Select from: Agilent/Varian, Blackfox, Bruker, Doty, JEOL, Home-built, Nalorac, PhoenixNMR, Q One, Tech MAG.	Yes
Model	Text entry of the probe model.	Yes
Serial Number	Text entry of the serial number.	No
Cooling Type	Select: Room Temperature, Helium, or Nitrogen.	Yes
Sample Diameter	Sample tube diameter in mm.	Yes
Field Strength	Field strength in MHz (¹H).	Yes
Gradients	Select: None, Z-axis, or XYZ.	Yes
X Gradient Strength	In G/cm; required only if XYZ is selected.	Conditional
Y Gradient Strength	In G/cm; required only if XYZ is selected.	Conditional
Z Gradient Strength	In G/cm; required if Z-axis or XYZ is selected.	Conditional
Status Details	Optional text description of probe condition or notes.	No

Operating Temperature Range

Field	Description	Required
From (°C)	Minimum operating temperature.	Yes
To (°C)	Maximum operating temperature.	Yes

Form section for adding probe Channels and Nuclei

Channels

Each probe may have one or more channels. Click Add Channel to create a new entry.

Channel Entry Fields (All Channels)

Field	Description	Required
Channel Number	Numerical designation of the channel.	Yes
Select Coil	Choose: Inner Coil or Outer Coil (radio button).	Yes
Cooled Preamplifier	Checkbox to indicate presence of cooled preamp.	No
Broadband	Checkbox to indicate if the channel is broadband.	No

If Broadband is Selected

When the Broadband checkbox is selected, a frequency range must be defined.

Field	Description	Required
Minimum Frequency (Nucleus)	Select a nucleus from a drop-down to define the lower frequency limit.	Yes
Maximum Frequency (Nucleus)	Select a nucleus from a drop-down to define the upper frequency limit.	Yes

All nuclei with frequencies between the selected range will automatically be associated with the broadband channel.

If Broadband is Not Selected

When the channel is not broadband, specific nuclei must be manually added.

Action	Description
Add Nucleus	Click the Add Nucleus button to open a selection menu. Nuclei are chosen from a pull-down list.
Multiple Nuclei Supported	More than one nucleus may be added per channel.

Once probe information is completed, use the Save Changes button to store the record or select Discard Changes to ignore.

Removing Probes

Once saved, probes cannot be deleted as they may be linked to experimental data collected via NDTS. If a probe is saved in error, and has no experimental data linked, please send a support request to support@usnan.org to have it removed. If the probe is no longer operational, update the probe status to 'Decommissioned'.
