Current Work

 * Determine an ideal process to assemble components of the fiber splicing unit.


 * Optimize and document a reliable, repeatable process for fusing 2mm x 2mm square optical fibers using a fiber splicing unit.


 * Work with James McIntyre to develop polishing, gluing, painting, and quality assurance procedures for optical fibers.


 * Develop/refine a LabView program that controls a water heater and water pump based on water temperature.

LabView Program
During the summer of 2012, Ben Willis wrote a LabView program that would communicate with a NetBooter and ultimately control a heater and water pump. LabView also plots the temperature of water being heated, and plots the changing temperatures on a graph on the front panel. Before Ben left, he wrote a [[media:Final_Report.pdf|final report]] of his work on the program and in the lab in general. I have added a little to Ben's work, mostly housekeeping; deleting some non functioning commands, adding the equation to represent temperature based on voltage, adding an equation for a thermocouple, and connecting with the DAQ. I also plan to make a differential op-amp to allow the DAQ to read the inputs given by the thermocouple. In this way, we will be able to use a thermistor and two thermocouples to control the water temperature in both the straightening pipe and the bending tank.

I had found a lab manual from the University of Minnesota that gave step by step instructions for taking and recording temperature measurements using a thermistor, a DAQ, and LabView. After making the circuit and updating the LabView program it seems to be working within expected error.

Temperature Measurements
Along with the LabView program, another component of bending fibers will be to determine the temperature of the water and to make that information available to the program.

At first, I had thought that our best bet as far as reading/recording water temperature was to make a thermistor (as seen below).

Completed Work

 * Clean and organize room P405.
 * Hot water tank constructed - still awaiting testing
 * Splicing unit collars redesigned
 * A program was written to automatically control a heater/pump based on the temperature of the water.
