A.Seryi, Jan 14, 2012, US-UK accelerator workshop Summary IDS-NF has achieved remarkable progress in the design of the Neutrino Factory (many problems have been solved, more definitions provided and mitigating scenarios identified) The IDR has been published! We need to progress technology solutions and develop the costing The work on the Reference Design Report (RDR – is to be published in the Summer 2013) work is ongoing The RDR will serve as a feasibility demonstration, shift the effort towards the engineering and provide the cost estimate for the facility. The large value of θ 13 would require a re-optimisation. The Neutrino Factory seems to have the best sensitivity for CP violation search, but more studies are needed for all facilities including realistic systematics. The definition of the incremental (staging) approach is needed. IDS – NF summary & synergies, Neil Bliss, STFC

A SECOND EXAMPLE: MACHINE DETECTOR INTERFACE Steve Geer Proton Accels. for Science & Innovation January,  Unique to a Muon Collider are detector backgrounds from muon decay.  For TeV muon decays, O(10 5 ) decays/m, but decay angles are O(10)  radians. Electrons typically stay inside beampipe for few meters. Hence decay electrons born within a few meters of the IP are benign. → sweep the electrons born further than ~6m from the IP into ~6m of shielding.  Understanding how to mitigate the backgrounds and developing detector technologies to do the physics at a Muon Collider provides an interface to the particle physics community. -Simulation tools exist, but there is an opportunity for an expanded effort -Developing detectors for high background environments has broader interest than just Muon Colliders → fruitful ground to explore collaboration ?

EMMA EMMA - demonstration of a linear non-scaling Fixed Field Alternating Gradient accelerator : Performed acceleration in serpentine channel (outside rf bucket) in around 10 turns. Achieved operation with large tune variation due to natural chromaticity during acceleration. Proves that a linear non-scaling FFAG works! Summary by Jaroslaw Pasternak

Proof of principle of the muon acceleration: -serpentine acceleration (demonstrated, but more lessons to be learned), -operation of NS-FFAG, Extrapolation of the results to future muon machines. Synergies mainly with IDS-NF and MAP, VLENF, PRISM (experimental test of phase rotation in NS-FFAG), but also with a medical FFAG, ADSR etc. It is important to extract as much output as possible from the EMMA commissioning (may be try to extend the EMMA life?)! 22 EMMA synergies Summary by Jaroslaw Pasternak
