CONFIG 14: 16-Apr-2018 to 16-Apr-2018 Fiber Bend Tests
In Line PSBS custom made by Mark, aligned on laser bench Pier 35, S/N 2. Test for sensitivity to fiber bending. We took out the PDBS and the fold mirror. PD2 is connected to the through channel and PD1 has a 9V battery. Fiber 31 is input and Fiber 21 is output. FISH Fibers, SIRCUS Sphere, Yuqin Zong's white LED source, monitor with Si PD and SEI. * E1 = Normal configuration. * E2 = Repeat normal configuration. * E3 = Lift output fiber to read "19" on the reference ruler (see photos). * E4 = Remove ruler, normal configuration. * E5 = Lift output fiber to read "19". * E6 = Remove ruler, normal configuration. * E7 = Move PD2 a little away from the chamber. * E8 = Put PD2 back where it was, approximately. * E9 = Wiggle PD2, losen, tighten FC thorlabs part, flex fiber cable * E10 = Move to intput fiber; bend it slightly backwards. * E11 = Input fiber as it was.
Figure 1: All data for Config 11 Fiber Bend. PD2 signals are normalized to the monitor. All are normalized to the initial value.
