1000	Filled LN2 cold trap
1220	Mixing chamber temperature 5.6 K. IVC pressure 4.6E-7 mbar. Looks good.
	Close condenser speedivalve and gate valve. Start cryocleaning mixture through nitrogen cold trap 2.
1345	Interrupt cryocleaning. Pump mixture into dump in preparation for condensation.
1445	Switch to tower thermometer. Close all valves on IGN in preperation for condensation. Pressure in G2 612 mbar.
	Start 1 K pot: temperature 1.8-1.9 K.
	Open condenser speedivalve and gate valve. Start condensing mixture with automated procedure through nitrogen cold trap 1.
1615	Mixture mostly condensed, but automated procedure leaves some in dump. Open valve V9 periodically to extract it. Switch back to mixing chamber thermometer.
