Busy conference for me. 3 posters, 1 talk, 3 satellite meetings, 4 receptions.
Mats, Miramar Castle
ALBA Synchrotron Light Source Commissioning - D. Einfeld (CELLS-ALBA Synchrotron)
warts and all...
LHC from Commissioning to Operation - M. Lamont (CERN)
Towards shorter bunch spacing, limited by e-cloud. Those darned UFOs
Study on the Realignment Plan for J-PARC Linac after the Tohoku Earthquake in Japan - M. Ikegami (KEK) T. Mor- ishita (JAEA/J-PARC)
Severe alignment errors, in some cases giving up on re-alignment, adding correctors.
[Could not attend Mon PM, as in a PRST-AB meeting... ]
Simultaneous Long and Short Bunch Operation in an Electron Storage Ring - a Hybrid Mode based on Nonlinear Momentum Compaction - M. Ries (HZB), J. Feikes, A. Jankowiak, P Schmid, G. Wustefeld (HZB) A. Hoehl, R. Klein, R. Muller (PTB)
Really neat technique making use of longitudinal phase space topology resulting from manipulating higher order alpha's.
First Results from the EMMA Experiment - S. Machida (STFC/RAL/ASTeC)
Struggling with large c.o.d. in attempts to demonstrate large acceptance.
LHC Upgrade Plans: Options and Strategy - L. Rossi (CERN)
2 interesting results, both positive:
Q_bb is 3 to 5 times better than expected (Dobrin can say more),
Injector chain emittance is 2 rather than the 3.75 of design.
Stochastic Cooling of a High Energy Collider - M. Blaskiewicz (BNL), J.M. Brennan, R.C. Lee, K. Mernick (BNL)
3D stochastic cooling demonstrated; a major milestone in acc.phys. Implications for HI operation of LHC.
ARIEL: TRIUMF's Advanced Rare IsotopE Laboratory - L. Merminga, F. Ames, R.A. Baartman, C.D. Beard, P Bricault, I.V. Bylinskii, Y.-C. Chao, R.J. Dawson, D. Kaltchev, S.R. Koscielniak, R.E. Laxdal, F. Mammarella, M. Marchetto, G. Minor, A.K. Mitra, Y.-N. Rao, M. Trinczek, A. Trudel, V.A. Verzilov, V. Zvyagintsev
Quite well received. + Comments afterward.
Non-scaling Fixed Field Alternating Gradient Permanent Magnet Cancer Therapy Accelerator - D. Trbojevic (BNL)
Unfortunately had about twice too many slides.
Observations of Beam-beam Effects at High Intensities in the LHC - W. Herr (CERN), E. Laface, G. Papotti, T. Pieloni (CERN)
Nice talk. Dobrin knows more...
Collimation Studies with Hollow Electron Beams - G. Stancari (Fermilab), G. Annala, V.D. Shiltsev, D.A. Still, A. Valishev (Fermilab)
Cool idea! By Gauss' law, circular hollow charge dist. has no electric field inside, so core is unaffected.
Overview of LHC Beam Loss Measurements – B. Dehning (CERN), et al.
Good, interesting talk.
Electron Cloud Observations in LHC – G. Rumolo (CERN), et al.
Trying to reach 25ns bunch spacing
Accelerator-driven Subcritical Molten-salt-fueled Reactors – R.P Johnson (Muons, Inc) C. Bowman (ADNA)
Exciting! A lot of flap in the news about this type of reactor as safer than Fukushima.
Theory of Microwave Instability and Coherent Synchrotron Radiation in Electron Storage Rings – Y. Cai (SLAC)
IMO, best talk of the conference. Clear, with extensive historical attribution. CSR impedance in discretized Vlasov equation. Good agreement.
Recent Developments in Hadron Sources – J.G. Alessi (BNL)
TRIUMF still rates a mention as best cw H- source.
Polarized H-: 1mA is now routine. This is the development started at TRIUMF.
First Years Experience of LHC Beam Instrumentation – O.R. Jones (CERN)
~5000 UFO events, of which 35 caused beam to dump.
Earth tide effect.
Synchrotron light has such high BW, can look at each bunch individually.
The European Spallation Source – S. Peggs (ESS)
No ring in this neutron source, so can use protons instead of H-.
Still using (TRIUMF-established) 1W/m loss allowance.
