SLS Vertical Emittance Tuning TIARA Kick-Off Meeting WP6 - "SVET" (E. Jensen/CERN) 23-Feb-2011 SLS Vertical Emittance Tuning Objectives, Organization, Timeline Erk JENSEN/CERN TIARA Kick-Off Meeting, CERN, 23-24 February 2011

TIARA Kick-Off Meeting WP6 - "SVET" (E. Jensen/CERN) 23-Feb-2011 The Main message: This is a Kick-Off Meeting: TIARA has started officially on January 1st, 2011! SVET project active during 30 months: January 1st, 2011 – June 30th, 2013

WP6 (SVET) SVET: “SLS Vertical Emittance Tuning” Objectives: TIARA Kick-Off Meeting WP6 - "SVET" (E. Jensen/CERN) 23-Feb-2011 WP6 (SVET) SVET: “SLS Vertical Emittance Tuning” Russian “Свет” means “light” Objectives: Convert the Swiss Light Source (SLS) to a R&D Infrastructure, Demonstrate ultra-small emittances as required for future Linear Collider Damping Rings (5 nm normalized, <1 pm @ 2.86 GeV) Enable to extend tests to lower energies (IBS dominated regime).

Small emittances TIARA Kick-Off Meeting WP6 - "SVET" (E. Jensen/CERN) 23-Feb-2011 Small emittances

TIARA Kick-Off Meeting WP6 - "SVET" (E. Jensen/CERN) 23-Feb-2011 The Main players PSI: Masamitsu Aiba, Michael Boege, Andreas Streun, ... CERN: Yannis Papaphilippou, Fanouria Antoniou, (?) BE-BI... INFN/LNF: Marica Biagini, Simone Liuzzo, Fabio Marcellini, Mario Serio, ... Max-IV Laboratory (via PSI): Åke Andersson, ...

What it takes: Step 1 Step 1: With the existing hardware: TIARA Kick-Off Meeting WP6 - "SVET" (E. Jensen/CERN) 23-Feb-2011 What it takes: Step 1 Step 1: With the existing hardware: Ensure optimum measurement accuracy (beam size, position, emittance, coupling, ...) Minimize magnetic field errors alignment of girders/magnets alignment of BPM’s Minimize betatron coupling (using exisiting skew quads) Result: Show what is possible & where improvements are needed. Interim report due in May, 2011 (Milestone), final report due: Month 9, September 2011

What it takes: Step 2 Step 2: With those results: TIARA Kick-Off Meeting WP6 - "SVET" (E. Jensen/CERN) 23-Feb-2011 What it takes: Step 2 Step 2: With those results: Specify the necessary improvements of Beam position monitors, Beam profile (emittance) monitors, Emittance control knobs, Magnet trimming coils and supplies Result: Specification of upgrades (Specifications due: Month 18, June 2012)

What it takes: Step 3 Step 3: Implementation of upgrade: TIARA Kick-Off Meeting WP6 - "SVET" (E. Jensen/CERN) 23-Feb-2011 What it takes: Step 3 Step 3: Implementation of upgrade: Down-select most important hardware to be implemented (financial constraints), planned: improved BPM’s and/or alignment correction knobs and feedback algorithms (automated coupling control) improved resolution/sensitivity beam profile monitor (laser based?) knob allowing energy scaling Fabricate hardware, Install hardware in SLS Result: An improved SLS, allowing to reach smaller vertical emittances at different energy levels. (Implementation due: Month 24, December 2012)

TIARA Kick-Off Meeting WP6 - "SVET" (E. Jensen/CERN) 23-Feb-2011 What it takes: Step 4 Step 4: Commissioning: Commission improved BPM and/or alignment system Verification of the automated coupling control Commission new beam profile monitor (the commissioning at lower energy is not formally included due to financial/time constraints) Result: Final report on obtained results, due Month 30, June 2013
