  3. BFW Card: Physics Overview (PRD 1.4-004-r1)

  4. BFW: Alignment & Assembly Status

  5. BFW: Alignment & Assembly Status

  6. BFW Card Prototype Drawing X-wire end point: 39.614 mm Beam center: 40 mm Gap between beam and X-wire: 0.386 mm Prototype material: Al-6061 Actual material: Macor Thickness: 3/16” (4.8 mm) Coating: Kovar [tooling in progress] Y-wire end point: 37.014 mm Beam center: 37.2 mm Gap between beam and Y-wire: 0.186 mm Courtesy: C. Field, R. Rogers

  7. BFW Card Wiring: Tooling Micrometer stage BFW Card Rods for hanging BFW wire with weights Card holder ‘Carbon wire & weight’ Copper Tabs • Wires soldered to copper tabs • Wires from copper tabs connect to BFW feedthrough • Feedthrough to be grounded and RF shielded Courtesy: C. Field, Y.Sung

  8. BFW Alignment Procedure at SLAC(outside Vacuum) • Coordinate system definition • Wire card positioning and alignment • Transformation Factor from BFW tooling balls  wire card QC Instruction List

  9. BFW Alignment Procedure (in Vacuum) • Wire position found using TB values • Repeatability check • Wire position check in virtual beamline coordinate system QC Instruction List

  10. BFW Test: Sample ‘Good’ Data, BFW #7 All Data, courtesy: SLAC QC, E. Lundahl, K. Caban, T. Nakashima

  11. BFW Test: Sample ‘Bad’ Data - old design of BFW #2

  12. BFW Test: Sample Data, BFW #12Vacuum Test 1 • Measurement Method: • Under Vacuum • 200 cycles, 10 measurements, Random sampling • Relaxation time between cycles: ~ 1 second

  13. Measurement Method: • Under Vacuum • Another 10 cycles, 10 measurements, Consecutive sampling • Relaxation time between cycles: ~ 1 minute BFW Test: Sample Data, BFW #12Vacuum Test 2 • BFW #12 RFI-ed • Tested for repeatability at ANL (All units are tested at ANL) • Wire position verified at SLAC • Wire repeatability verified with delayed cycles (small sample size) at SLAC • SLAC Procedure to calibrate devices using small sample size + delayed cycle measurement

  14. BFW : Status Reminder Process Time per Assembly: ~ 1 day
