  9. MICE Absorber Test Process and Test Cryostat

  10. MICE Absorber Test Process 3-5 Bodies by (KEK) 6-10 Windows by (USA) 20K Gas-He Test at (KEK) Test check absorbers & assemble in MICE at RAL L-H2 Test at MTA with a Spare Body and Windows

  11. Detail Test Process (3) At US/FNAL Pressure Test at room temperature KEK (1) Pressure Test at room temperature with Dummy Windows (2) Pressure Test with Dummy Windows & 20 K gas-He (4) Pressure Test at rum temperature with Windows (5) Pressure Test W/gas He at 20K temperature with Windows At KEK (or FNAL) (2)&(5) Needs Test Cryostat (A) Test Cryostat at MTA  L-H2 Test (B) New Horizontal Test Cryostat  Cold gas-He Test RAL (6) Pressure Test at room temperature (7) Cooling Test W/gas-He (8) Cooling Test W/L-H2

  15. LH2 Level Sensor and Thermometers

  16. LH2 Level Sensor and Thermometers CX-1050SD

  17. LH2 Level Sensor Needs LH2 Level Monitor - Cooling Experiment - Operation Requirement - Safety Requirement No Space for Capacitance Level Sensor (AMI) D= 1/2”, L > 5” Resistance Thermometer T = TB+ dT, R = RB+ dR Level Monitor by Resistance Thermometer with high current I ~ 10 x INORMAL Liquid Level T = TB , R = RB

  18. Calibration of LH2 Level Sensor x5 Down parts are for the Solid H2 Target

  19. Wiring and Connecters Thermometers and Level Sensor in LH2 32 pin Connecter on KF40 Thermometers in Vacuum 32 pin Connecter (1 of 2) on KF40

  20. Wiring and Connecters ( I ) Thermometers and Level Sensor in LH2 LH2

  21. Wiring and Connecters ( II ) vacuum(CX-1050SD except “LH2 TOP”) Thermometers in Vacuum

  22. Summary • MICE absorber(No.1) will arrive soon. • Horizontal test cryostat will be designed and fabricated at KEK. • (3) MICE absorbers will be tested at KEK W/ cold gas-He at 10-20K. • (4) MICE absorbers will be shipped to RAL with sensors and real windows (ready to use).  PROPOSE • (5) L-H2 test at FNAL/MTA with a spear MICE absorber. •  PROPOSE • (6) Thermometers/LH2 level sensors and wiring/connecters are existing.
