Current Work
Summer 2017
This summer, I (Micah Warren) am constructing seven new bundles to replace old ones in the tagger microscope. The following pages provide documentation:
Rough Cut Documentation Summer 2017
Pockmark Documentation Summer 2017
2015 and Earlier
We are currently in production of 12 additional fiber bundles to replace bundles which are currently installed in the microscope. We found that our light guide fibers were not double clad, but were only single clad. In August and September of 2014, we received a new order of BCF-98 and BCF-20 which we verified as multi-clad using EDX techniques. In addition to having a second cladding layer, we are also attempting to maintain the optical qualities best by minimizing strain on fibers by removing some of the fiber procedures.
Current progress is being kept in the Fibers - 2015 Google Spreadsheet.

Fiber Statistics
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
New Ferrule Measurement Photographs
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.

Hot Air Bending Box
After our experience with with heating fibers in water for straightening and bending, we decided to change our procedure and use hot air instead of water. The following pages show information about the heating box and the program used to run it.
