=== Proposed Measurement Program ===

# Irradiation with about 40 rem over the course of a few days (source strength selected appropriately) with ''full measurement'' performed periodically.

# Irradiation with monitoring until the dark rate in the SiPM has increased by a factor 2 over the initial conditions, then allow the SiPM to self-anneal and monitor its recovery.

# Relaxation time (of duration determined by the apparent healing rate)  with ''full measurement'' performed periodically.

# Monitoring will consist of ''full measurements'' (see below) taken at several points during irradiation, and periodically during annealing.

# Repetition of 1. and 2. as desired to determine the recovery extent

# The initial period between measurements while irradiating should be 1 rem, to be adjusted after a trend is observed.

# Proceed with a longer irradiation period until significant curvature is seen in the change of the performance parameters in order to measure the decay function (e.g. two exponential?)

# The initial period between measurements while annealing should be one day, to be adjusted after a relaxation time is observed.

# Once the data up to factor-2 dark rate increase and subsequent annealing have been analyzed, proceed with a longer irradiation period until significant curvature is seen in the dark rate vs. dose curve. then repeat the annealing measurements to compare with the initial relaxation rates.

# Irradiate the unit for a much longer duration - until some saturation of the performance parameters is seen. This will help determine the offset in the model of the deterioration of performance parameters.
