LabView Program
This page details the work that has gone into the LabView program that was written to control the heaters and pumps for the bending tank in 405.

LabView Program Explanation

Temperature Measurements
This section describes the work that has gone into the construction of the thermistor for the bending tank in 405. It also has some materials devoted to describing the function and properties of a thermistor and the method used to build the one used here.

=Miscellaneous Fiber Testing=

Below are the various tests that were conducted on the fibers to determine their durability when in contact with the alcohol that will be used to clean them. Also included are the strength tests that were conducted on the fibers that were fused with the old ferrules.

=Ferrule Measurements=

In hopes of understanding the bulge in the spliced region of the fibers, the ferrules they are spliced in were photographed under a microscope and measured using a tracker program that allows for in-photo calibration and measurement. The ferrules were placed as perpendicular to the table as possible in order to get the most flat, head on shot of the ferrules. The error in the measurement of the angles was quite high. Moving the compass only a little bit (in the tracker program) lead to very different degrees read. Because of this I would estimate the angle to be off anywhere from +- 1-2 degrees. I would say that the lengths measured have an error on the order of +- .05-.1 mm

=Quality Control Procedures= Fiber transmission measurements were carried out in Lab 402 using a flash ADC and a VME-based data acquisition system that was loaned to UConn by Jefferson Lab. Our contact at Jlab for this system is Alex Somov. Setup and operation of the CODA data acquisition platform is described here.
