CFRP (1mm) L.T. System g
40 mm ~500 mm 145 mm Target Kapton Cell Temperature sensor (Cernox) Target stage 25mm 33 mm
Target Cell (Kapton 125 um) Nagai manufacturing Co.,Ltd. ( www.nagai-mfg.co.jp ) Plastic molding, etc. Leak test (2 atm) using N2 gas.
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.
