TUPPD015  Optimization of Muon Capturing in g2 Ring  1440 


We describe optimization procedure for muons capturing in g2 ring under reconstruction at FERMILAB. This procedure includes both the beam dynamics consideration and HV inflector geometry and technique. Some engineering aspects of HV inflector and pulser are presented in detail.  
TUPPR066  Characterization of Single Particle Dynamics for the International Linear Collider Damping Ring Lattice  1972 


Funding: DOE Award DESC0006506 The baseline design for the International Linear Collider damping rings is a 3.2 km circumference racetrack, with 5 GeV beam energy. The transverse damping time is 26 ms and the normalized horizontal emittance 5 mmmrad. Nearly 60 2.2mlong superconducting wigglers per ring increase the radiation damping rate by an order of magnitude and reduce horizontal emittance by a factor of 5. We characterize the sensitivity to magnet misalignments and field errors, and establish the minimum numbers of corrector magnets and beam position monitors required for tuning vertical emittance to less than 20 nmrad. We validate the specified tolerable guide field multipole errors consistent with adequate dynamic aperture. Tune scans are used to identify stable working points. In tracking studies we use a wiggler model based on fits to 3dimensional field maps.
