*16: TG is an isolation gate between vertical register and horizontal register. In standard operation, the same pulse as P2V should

be applied to TG.

*17: If the current is greater than Imax, the heat absorption begins to decrease due to the Joule heat. It should be noted that

this value is not a damage threshold. To protect the thermoelectric cooler and maintain stable operation, the supply

current should be less than 60 % of this maximum current.

*18: Temperature of cool side of thermoelectric cooler

*19: Temperature of hot side of thermoelectric cooler

*20: This is a heat absorption when the maximum current is supplied to the TE-cooler.
