COMMAND

DESCRIPTION

IFOpen He3nmr

Opens the 3He interface

IFClose He3nmr

Closes the 3He interface

IFTalk He3nmr "He3PolEnabled()”

Returns “1 = 3He polarizer Enabled?” if the 3He interface is initialized

Returns “0 = 3He polarizer Enabled?” if the 3He interface is not initialized

IFTalk He3nmr “He3AnaEnabled()”

Returns “1 = 3He analyzer Enabled?” if the 3He interface is initialized

Returns “0 = 3He analyzer Enabled?” if the 3He interface is not initialized

IFTalk He3nmr “He3PolFlipOff()”

Function flips the polarizer 3He spin to “UP” or "0" state

Returns “0 = 3He polarizer state”. It does nothing if the state is already “UP” or "0"

Automatically toggles back to the NMR configuration

IFTalk He3nmr “He3PolFlipOn()”

Function flips the polarizer 3He spin to “DOWN” or "1" state

Returns “1 = 3He polarizer state”. It does nothing if the state is already “DOWN” or "1"

Automatically toggles back to the NMR configuration

IFTalk He3nmr “He3AnaFlipOff()”

Function flips the analyzer 3He spin to “UP” or "0" state

Returns “0 = 3He analyzer state”. It does nothing if the state is already “UP” or "0"

Automatically toggles back to the NMR configuration

IFTalk He3nmr “He3AnaFlipOn()”

Function flips the analyzer 3He spin to “DOWN” or "1" state

Returns “1 = 3He analyzer state”. It does nothing if the state is already “DOWN” or "1"

Automatically toggles back to the NMR configuration

IFTalk He3nmr “He3PolGetState()”

Function returns “0 = 3He polarizer state” or “1 = 3He polarizer state”

IFTalk He3nmr “He3AnaGetState()”

Function returns “0 = 3He analyzer state” or “1 = 3He analyzer state”

IFTalk He3nmr "He3PolGetNumFlips()”

Function returns “# = actual number of flips for polarizer”

IFTalk He3nmr "He3AnaGetNumFlips()”

Function returns “# = actual number of flips for analyzer”

IFTalk He3nmr “PolarizerFID()”

Function does an FID NMR measurement for polarizer and returns a number of fit parameters

Automatically tunes solenoid current to measurement value, then back for the experiment

IFTalk He3nmr “AnalyzerFID()”

Function does an FID NMR measurement for analyzer and returns a number of fit parameters

Automatically tunes solenoid current to measurement value, then back for the experiment

IFTalk He3nmr “FIDSetField(value)”

Sets the solenoid current: either the FID NMR/AFP flipping measurements or the experiment

Value is a number ranging from 1.5 to 5.2 A.

Software and hardware limit protection is built in

We do not suggest using it if not necessary. (Call us before using this command)
