CONFIG 11: 19-Mar-2018 to 20-Mar-2018
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 = Day 1: 19-Mar-2018 Chamber Door open, LED on 19:06, baseline run. * E2 = Day 1: 19-Mar-2018 Move PDs close to chamber wall to create slack, this puts a bend in fiber 21 of radius about 18cm. * E3 = Day 1: 19_Mar-2018 Move PDs back to original position. * E4 = Day 2: 20_Mar-2018 File 001, LED on 14:40. Bend Fiber 21 (output) vertical - 0.88" high block, overhead Bank 4 on, Chamber light on by mistake, Chamber door open for all data * E5 = Day 2: 20_Mar-2018 File 002, Bend Fiber 21 (output) vertical - 0.88" high block, overhead Bank 4 off, Chamber light on by mistake * E6 = Day 2: 20_Mar-2018 File 003, Bend Fiber 21 (output) vertical - 0.88" high block, overhead Bank 4 off & Chamber light off, stays off for rest of data * E7 = Day 2: 20_Mar-2018 File 004, Bend Fiber 21 (output) vertical - 1.0" high block * E8 = Day 2: 20_Mar-2018 File 005, Bend Fiber 21 (output) vertical - 1.0" high block, move block left towards PD side one "shelf rung width" * E9 = Day 2: 20_Mar-2018 File 006, Bend Fiber 21 (output) vertical - 1.0" high block, move block right, back to first position (7 rung spaces, 5.5") * E10 = Day 2: 20_Mar-2018 File 007, Bend Fiber 21 (output) vertical - 0.86" high block * E11 = Day 2: 20_Mar-2018 File 008, Bend Fiber 21 (output) vertical - 0.86 + 0.26" high blocks * E12 = Day 2: 20_Mar-2018 File 009, Bend Fiber 21 (output) vertical - 0.86 + 0.26 + 0.377" high blocks * E13 = Day 2: 20_Mar-2018 File 010, Bend Fiber 21 (output) vertical - 0.86" high block * E14 = Day 2: 20_Mar-2018 File 011, Bend Fiber 21 (output) vertical - 0.86 + 0.26 + 0.377" high blocks * E15 = Day 2: 20_Mar-2018 File 012, Bend Fiber 21 (output) vertical - 0.86" high block * E16 = Day 2: 20_Mar-2018 File 013, No Bend Fiber 21 (output) vertical - remove all blocks * E17 = Day 2: 20_Mar-2018 File 014, No Bend Fiber 21 (output) vertical - wiggle fiber, still no blocks * E18 = Day 2: 20_Mar-2018 File 015, No Bend Fiber 31 (input) vertical (no blocks) * E19 = Day 2: 20_Mar-2018 File 016, Bend Fiber 31 (input) vertical 0.86" this block is 7.25" from right chamber wall (by LED)) * E20 = Day 2: 20_Mar-2018 File 017, Bend Fiber 31 (input) vertical 0.86 + 0.26" this and E19 seem to be outliers * E21 = Day 2: 20_Mar-2018 File 018, No Bend Fiber 31 (input) vertical (no blocks) * E22 = Day 2: 20_Mar-2018 File 019, Bend Fiber 31 (input) vertical 0.86" * E23 = Day 2: 20_Mar-2018 File 020, Bend Fiber 31 (input) vertical 0.86 + 0.26" * E24 = Day 2: 20_Mar-2018 File 021, Bend Fiber 31 (input) vertical 0.86 + 0.26" wiggle fiber first * E25 = Day 2: 20_Mar-2018 File 022, No Bend Fiber 31 (input) vertical (no blocks) * E26 = Day 2: 20_Mar-2018 File 023, Bend Fiber 31 (input) vertical 0.86 + 0.26" this and E19 seem to be outliers * E27 = Day 2: 20_Mar-2018 File 024, Bend Fiber 31 (input) vertical 0.86" * E28 = Day 2: 20_Mar-2018 File 025, No Bend Fiber 31 (input) vertical (no blocks)
