  1. LHC Sync. Light Monitors Status and Plans 05 Feb 2014 Emittance Meeting (~= BI-TB Jan 2014) F.RoncaroloA.Goldblatt, G.Trad, E.Bravin, S.Mazzoni, W.Andreazza, G.Shneider,M.Wendt, N.Chritin

  2. Overview • BSRTM Design • Option A: original design with ceramic pieces • Option B (BASELINE): Longer mirror, support behind RF screen, all metal • Optics • Low wavelength optics • Interferometer (B1 only) • New calibration line (B1 only) • Change tank support from ‘chair’ to 3 pillars (B1 only?) • New light shielding • SW • New functionalities to cope with new optics layout • Filter wheels  pneumatic IN-OUT • Interferometer • Possible request of tomography meas. (ABP)  fastest and synchronized camera acquisition • Discussion on Digital Cameras

  3. New Calibration Line BSRTR B1

  4. New Calibration Line BSRTR B1 ECR circulating System (BSRTR = BTVSI modified) in production expected delivery: March Scheduled installation: March Components outside vacuum to be ordered, not critical, will be installed fall 2014

  5. BSRTM Option A (ceramic) Mirror holder components (except springs) made in ceramic 2 systems in fabrication Expected delivery Keep as backup solution

  6. BSRTM Option B For both option A and B, see BI-TB Oct 2013 for details on RF studies • BASELINE Option • ECR submitted • 2 systems in fabrication • Expected Delivery: February • Schedule • RF tests in the LAB? • To TE-VSC for testing: 15 March • Installation: April ?

  7. Tank Support Proposal: change B2 immediately, to free space for halo monitor Decision: change B1 support from ‘chair’ to 3 pillars (existing) to free space on optical table

  8. Optics Layout

  9. New mirrors • 2 mirrors compatible with option B, coating visible : arrived, backup solution • 3 mirrors with coating in the UV (down to 230nm) for option A + 3 for Option B • Expected delivery end of February • Can be the bottleneck for scheduling

  10. New Light Shielding

  11. Digital Cameras
