LabView viís (updated 5/13/2016)

These archives each contain several different viís, and a .pdf file with documentation for all of them.Brief descriptions of the vi's are:

         Coincidence.vi
This is the program we use to run 4 different experiments: simple coincidence counting, measuring g(2)(0) with a single beam and 2 detectors, measuring g(2)(0) with 2 beams and 3 detectors, and single photon interference.

         Hardy-Bell.vi
This is the program we use for testing a Bell inequality, or for Hardyís test of local realism.The program can accommodate either 2- or 4-detector measurements.

         MCA.vi
This is the program we use to allow an A/D board to mimic the behavior of a multichannel analyzer.We wrote this vi because a multichannel analyzer is a fairly specialized piece of apparatus, while A/D boards are more commonly found in undergraduate laboratories.

         Coincidence_time_res.vi
Use this program to calibrate the time resolution of your coincidence measurements.Needed for 2-detector g(2)(0) measurements and for accidental coincidence subtraction.

         Angle_scan.vi
Use this program to examine two photon polarization correlations (joint probabilities) as a function of angle.

         QSM_rs232.vi

Used to measure the polarization state of a single photon.

LabView V. 2015 viís for DE2 Coincidence Unit (from 2016)

These viís were written to use the Whitman DE2 coincidence counter to acquire data.Data streams from this counter to the computer over an RS-232 serial port.These vi's support the Newport NewStep rotation stages (NSR1); and have been updated to include a ďManualĒ mode to allow for manual setting of the rotation stages.

 

Click here LabView 2015 DE2 to download a .zip archive containing these viís.These viís are all native LabView 2015 code.

Simple executable .vi for DE2 Coincidence Unit (from 2013)

A Windows installer that installs Coincidence.vi; it uses theWhitman DE2 coincidence counter to acquire data.Data streams from this counter to the computer over an RS-232 serial port.This vi will support the Newport NewStep stepper motor, but you donít need a stepper motor to run it (simply leave ďNewStep?Ē set to ďNoĒ). All you need to set is the COM port connecting to the DE2 and youíre good to go. Full documentation is available with the regular labview code here.

LabView V. 2011 viís for DE2 Coincidence Unit (from 2012)

These viís were written to use the Whitman DE2 coincidence counter to acquire data.Data streams from this counter to the computer over an RS-232 serial port.These vi's have been updated to support the Newport NewStep rotation stages (NSR1). They also include a new program to perform quantum state measurement.

LabView V. 8.2 viís for DE2 Coincidence Unit (from 2008)

These viís were written to use the Whitman DE2 coincidence counter to acquire data.Data streams from this counter to the computer over an RS-232 serial port.

 

Click here LabView 8.2 DE2 to download a .zip archive containing these viís.These viís are all native LabView 8.2 code.

LabView V. 8.2 viís for PCI-6602 (from 2007)

These viís were written to use the National Instruments PCI-6602 counter to acquire data.They will work with TAC/SCA coincidence determination, or with the Trinity/Whitman discrete IC coincidence circuit.

 

Click here LabView 8.2 to download a .zip archive containing the viís for Labview version 8.2.These viís are sort of a kludge.They were converted from LabView 7 by saving all the viís (including those from the vi.lib).They donít use the native LabView 8 data acquisition routines (DAQmx).

Original LabView V. 7 viís (from 2006)

These viís were written to use the National Instruments PCI-6602 counter to acquire data.They will work with TAC/SCA coincidence determination, or with the Trinity/Whitman discrete IC coincidence circuit.
