== '''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.

=== '''Basic Information''' ===
{| class="wikitable"
! 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

| '''From (°C)''' || Minimum operating temperature. || Yes
|-
| '''To (°C)''' || Maximum operating temperature. || Yes
|}
[[File:Probe-channels.png|thumb|450x450px|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)''' ====
{| class="wikitable"
! 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.

{| class="wikitable"
! 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.

{| class="wikitable"
! 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'.
