  1. Liquid target system for New TPC experiment System Target cell Performance in test experiment Plan for next experiment Perspective

  2. CFRP (1mm) L.T. System g

  3. 40 mm ~500 mm 145 mm Target Kapton Cell Temperature sensor (Cernox) Target stage 25mm 33 mm

  4. Target Cell (Kapton 125 um) Nagai manufacturing Co.,Ltd. ( www.nagai-mfg.co.jp ) Plastic molding, etc. Leak test (2 atm) using N2 gas.

  5. Shielding

  6. Operation • 145 mmlong target cell Filled gas with 1.35 atm using default preserver tank (120x6 litter) • Temperature controll (Lake Shore) set requested temperature g The heat voltage is controlled automatically.

  7. 17K 15.8K Test(Hydrogen)

  8. For next experiment 100 mm longer

  9. 2 T Target Collimator Hole 31.7x24 mm Setup 33x25 mm (100)3 mm Tg=3 GeV, Ng=105, (sx,sy)=(8mm,4mm) (In&Out&Upbar) No LH2 3 No buffer 11 LH2 12

  10. Further • Helium 4 The liquidized was achieved using copper cell at Suzuki co. R&D for the target cell Kapton g Aramid, etc.
