Sensors for irradiation in April
2001/April/05

  Summary of microdischarge onset voltages.

  Ham-F: I-V measured as "bare" sensor, al metal floating
  KEK-G: I-V measured as "irradiation" assembly, al metal bonded together
		and grounded (=strip bias)
  KEK-F: I-V measured as "irradiation" assembly, al metal bonded together
		but floating (=disconnected from strip bias)

  KEK measurement: 26 deg.C, 6 min./0-500V
