LH Fall 2013

September 2013
Sept 1-7 (Total: 5.25 hours)- This week I spent some time taking measurements from the fusing unit to make sure the lamp is strong enough to fuse the fibers within spec. I researched different lamps from Eiko and lenses from various sites which could increase the strength of the light.

Sept 8-14 (Total: 7 hours)- On Monday, I cleaned the fiber collars of the apoxy which held the ferrules in place. I also took voltage measurements of the thermistor because the LabView program needed to be modified. Wednesday I helped Ann Marie with making sure the thermistor was waterproof. I also started the drawings for the styrofoam cut-outs for when we take the fibers and microscope pieces down to JLab. Thursday I worked on the styrofoam drawing more.

Sept 15-21 (Total: 7 hours)- This week I spent a lot of time working on drawings. Last week there was a miscommunication, and I have to create a styrofoam cut-out for the microscope all constructed. This will be done after I finish the drawings for the backplane and chimney. Thursday I talked to Alan and discussed the TurboCad drawing for the backplane. It will require multiple drawings and construction holes 0.375" dia and 6" apart. Hopefully we can find a place to split the drawing well to take advantage of the many arrays of holes.

Sept 22-28 (Total: 7 hours)- Because the part is 61" long, I decided to do 4 "windows" so that Alan can properly cut the part. The middle two windows are identical in length of 15" so that Alan only has to program 3 times instead of 4. I finished the drawings for window one this week. It required three separate drawings to properly and cleanly represent all of the holes. I will have to wait for Alan to come back from vacation until we can discuss the locations of the construction holes etc. Jim got me the dimensions and taps of all the holes.

October 2013
Sept 29- Oct 5 (7 hours)- This week I finished the rest of the drawings Alan required for the back plane to be machined. I discussed with him the parts that we'll need for machining: 2 boxes of tap pieces, 1 end mill, and the aluminum. After that was finished, I worked on the AutoCAD drawings of the various parts for both the Gluing and Bending stations. I had previously worked on them so I just finished and printed. And finally on Thursday, Oct 3rd, I cut and sanded some scintillating fibers for Ann Marie to fuse, and I also broke some fibers which she had previously fused. All the information I recorded went into a Google Doc and was shared with her.

Oct 6-12 (7 hours)- I started the week off by inputting some fiber bundle measurements that Kenny had taken into the official Google Doc. After that, I emptied the tank again because Ann Marie and Brendan had modified the piping. I also spent some time cleaning up 405.
