  1. Status report for Helium bag and Gauss meter installation for D52009.9.24Hiroshi Kou

  2. ☆Helium bag design and arrangement ・Helium bag is designed for reducing multiple scattering in D5 magnet. ・D5 magnet have arch formed hole. The hole size is 380×120. ・ Helium bag is designed through the magnet’s hole. ・The bag’s thickness is 38μm about the part of passing particles . (the other part is all 50μm ) ・The bag is made using Mylar. ・gas connector is connected sinflex tube (called 64) ・The bag is manufacturing now and delivered September 24th or 25th. arch formed hole end guard Fig.1 the design of D5 magnet Part of passing particles Fig.2 the design of Helium bag

  3. ・In D5 magnet,magnet's center and particle's orbit center is different (~60.9mm) ・The center of magnet is ~1100mm from end-guard and Gauss meter's tube is ~2000mm. ・we put hole probe on the 　 magnet center ・I designed Gauss meter and hole probe holder. ☆The arrangement plan about Gauss meter Hole probe 60.9 1100 Gauss meter 68.75° red:particle orbit blue:magnet center 55° Fig 3.difference of center in D5 magnet

  4. ・hole probe holder will be arranged,from the end-guard to the magnet center ・the probe has to be fixed perpendicularly to the magnetic field ・clear cover is designed to protect probe's head from the helium bag's pressure ☆the design of hole probe holder Magnet center end-guard Probe 3 Clear cover Fig.4 the design of hole probe holder

  5. ・There is a limited space to install the Gauss meter holder between D5 end-guard and Beam-line chamber. ・aluminum plate(the thickness is ~1cm) is necessary for attaching the Gauss meter holder ・we need request support for tapped holes to fix aluminum plate on D5 magnet ☆the design of Gauss meter holder CDS 6.875° Beam line chamber beam 56cm ~6cm D5 end-guard Fig5. The arrangement plan chamber and CDC end-guard Gauss meter holder Anchor hole Aluminum plate Fig 6.the arrangement plan of Gauss meter holder

  6. ・Range stack holder → installed already ・Helium bag →　delivered by September 24th or 25th ・Hole probe holder and Gauss meter holder → manufacturing now,delivered until September 28th and installedaround September 30th ☆time table
