1. MICE LH2 ABSORBER BODY Shigeru ISHIMOTO KEK OCT-10-2003 Non-Welding Bolt-Type Absorber

2. 1.Non-Welding Flange 2.SS-Bolt + Helisert 3.Double-Indium-Seal and/or Double-Helicoflex-Seal 4.Key Structure to Prevent the Slip Due to Thermal Expansion 5.Fit to Ed’s Vacuum Vessel and KEK Test Cryostat 6.G10-Support 7.Option Screws for Thermometers * KEK funds to build new test absorber in FY03. * Use KEK cryostat as MICE test bench at FNAL Proposed Design

3. D300 Absorber in KEK Test Cryostat

5. KEK Test Cryostat with D300 Absorber (Now at FNAL)

6. D300 Absorber in MICE Vacuum Vessel

7. In-seal and Helicoflex/Metal seal on same body

8. D300 Absorber in MICE Vacuum Vessel

10. 1.We need non-welding flange to fabricate and maintenance, also for solid targets. 2.We can use bolt-type flange for LH2 absorber if we use Helisert on the aluminum body. 3.Indium and/or Helicoflex seals will work well at 20K. 4.KEK cryostat is possible to use for D300 absorber test. 5.KEK funds to fabricate D300 test absorber in FY03.
