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 ranges.

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

Channels

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

Channel Entry Fields

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, additional fields are required:

Broadband Frequency Range

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

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

Otherwise, for non-broadband channels, individual nuclei may be added using the Add Nucleus button. This opens a selection menu to assign one or more nuclei to the channel.

Once probe information is completed, use the Save button to store the record. The probe will be listed under the associated spectrometer in the facility’s instrument list.
