Dark Current:

• < 50 pA/pixel at a gain of 5x10⁵ after cooking no more than 24 hours.

Linearity:

• Linear to within 10%.
• Input pulse should be triangular and no greater than 50ns FWHM.
• Anode charge output of 32fC to 100pC per channel at a gain between 10⁵ and 5x10⁵.

Crosstalk:

• Less than 5%
  • At gains of 10⁵ and 5x10⁵.
  • For input pulses as large as 100pC/pixel.
  • For background currents as high as 2.25uA.

Channel to Channel Signal Variation:

• Less than 3:1.

Integrated Equivalent Quantum Efficiency:

• More than 5% required.
• More than 8% desired.

LED Stability:

• Anode response stable to within +/- 2% of initial value for an on/off cycling of background current over a 48 hour period.

High Voltage Stability:

• Anode response stable to within +/- 2%.
• Procedure:
  1. Measure tube response to fixed light source
  2. Turn off HV for at least 10 min.
  3. Turn on HV again
  4. After 10 min. measure anode response again.
