Shape is sure to fall into disorder if mppc is a saturated condition.

The measuring method of the response curve is established.

  • y: ADCpulse height

  • x:rotation number of polarizing plate(×4.5°)

    A flat area is seen in mppc plot. The saturated condition was able to be confirmed.

plan

  • Evaluation of reproducibility

    by the same sample.

    1, Reproducibility of polarizing plate and laser.

    2, Reproducibility when mppc is pulled out and opened.
