From Vladimir Ivanovich Datskov

• “Today I tested quench heater white wire with CLIQ pulse current at SM18. With CLIQ Cbox1 (C=28 mF) I did total 10 current pulses 387 A, 770 A and 1 kA via Q-heater wire 1 m long (R=12.9 mOhm). After 387 A pulse the wire temperature was not changed, only after 1 kA pulse the temperature was 40-50 C.”
