Joint Belle SuperB Background Meeting Feb 9 – 10, 2012 SuperB SR bkgds 1 SR Backgrounds in SuperB M. Sullivan For M. Boscolo, K. Bertsche, E. Paoloni, S. Bettoni, F. Bosi, P. Fabbricatore, P.

Joint Belle SuperB Background Meeting Feb 9 – 10, 2012 SuperB SR bkgds 2 Outline IR design parameters SR power in the cryostat SR power and backgrounds near central beam pipe Summary

Joint Belle SuperB Background Meeting Feb 9 – 10, 2012 SuperB SR bkgds 3 Parameters used in the IR designs Parameter HER LER Energy (GeV) Current (A) Beta X* (mm) Beta Y* (mm) Emittance X (nm-rad) Emittance Y (pm-rad) Sigma X (  m) Sigma Y (nm) Crossing angle (mrad)+/- 30

Joint Belle SuperB Background Meeting Feb 9 – 10, 2012 SuperB SR bkgds 4 General IR Design Features Crossing angle is +/- 30 mrads –Tried 33 mrad – total crossing angle of 66 mrad – but found that SR backgrounds from large transverse (high sigma) orbits caused too much background on the detector beam pipe Cryostat has a complete warm bore –Both QD0 and QF1 are super-conducting –Also the extra focusing quadrupoles for the HER (QD0H and QF1H)

Joint Belle SuperB Background Meeting Feb 9 – 10, 2012 SuperB SR bkgds 5 More general details PM in front of QD0 –The magnet strength is as high as reasonable in order to get the most focusing in as close as possible to the IP –Also makes the beam pipe size 6mm radius under these magnets Soft upstream bend magnets –Reduce the SR power in IP area as much as possible. This applies especially to the inside walls of the cryostats.

Joint Belle SuperB Background Meeting Feb 9 – 10, 2012 SuperB SR bkgds 6 General details (3) BSC to 30  in X and 100  in Y (7  fully coupled) –This is as large as we could make it. Need at least sigma for injection aperture and in this case larger is better especially since injection is continuous SR scanned to 20  in X and 45  in Y –There is a gap between the SR scanned area and the BSC. Presently assume that collimators will block most beam particles in this region (20 to 30 sigmas). This will need to be modeled further.

Joint Belle SuperB Background Meeting Feb 9 – 10, 2012 SuperB SR bkgds 10 SR power inside the Cryostat

Joint Belle SuperB Background Meeting Feb 9 – 10, 2012 SuperB SR bkgds 11 Beam pipe close up 45 W 2 W 200  A little out of date 88 W 900  Surface design work needed 9 W 0.04 W 2  33 W 65 

Joint Belle SuperB Background Meeting Feb 9 – 10, 2012 SuperB SR bkgds 12 Summary The SR backgrounds have been studied fairly carefully and backgrounds look to be under control. Studies need to be continued. The SR power levels are manageable and ordinary water cooling of the beam pipes should be adequate for controlling the temperature of the beam pipes. The exact engineering details need to be worked out. This has already been done for the central beam pipe.
