Overview of Experiments Breakdown Meeting 1st of November2011
SYSTEM I: TemperatureDependence TypicalExperiment • Considerations: • - Cu/Cu tip and sample • - LN coilexchanged • -Lowest T reached: -92°C (beforeitwas -120°C) • Gap Measurement: some times itgivesproblems at low T, althoughnot as much as at High T Breakdown 1st November 2011 R. Santiago Kern
SYSTEM I: TemperatureDependence • Thereis a difference in breakdownfieldforambientorlow T of 15% approx. • looks likethiscoppersample has a especiallylowEb • This are lowstatistics Breakdown 1st November 2011 R. Santiago Kern
