MRSO PREP questions with correct answers
Zero Boil-Off - correct answer System that reduces/eliminates the need to recharge Helium in a magnet. Quench - correct answer Quickly eliminating the magnetic field. Not immediate, takes 3 to 5 minutes to completely eliminate magnetic field. Loud Noise as Helium rushes out of Quench Vent. Can cause crack in the wire (very costly to repair/replace). Ohm's Law - correct answer Resistance that is equal to Voltage divided by the amperage in a wire. V=IR Use of Cryogen reduces/eliminates heating with high voltage and amperage which allows for high magnetic field. Cryogen - correct answer Liquid Helium 42* Kelvin Dual Cryogen System - correct answer Helium
