IFOpen HeInterface

Opens the ³He interface

IFClose HeInterface

Closes the ³He interface

IFTalk HeInterface "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 HeInterface “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 HeInterface “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 HeInterface “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 HeInterface “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 HeInterface “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 HeInterface “He3PolGetState()”

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

IFTalk HeInterface “He3AnaGetState()”

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

IFTalk HeInterface "He3PolGetNumFlips()”

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

IFTalk HeInterface "He3AnaGetNumFlips()”

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

IFTalk HeInterface “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 HeInterface “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 HeInterface “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.
