Hey coolanter,
I expect that three people come. Chris will come as a beginner.
LN2 is not a problem, if you do not come on weekend. I would have to discuss that again with my contact man. It is improbable to come in on weekend.

We could naturally also buy LN2, do you know someone, who possesses a Dewar? On the other hand we could transfer completely to LN2. DICE is now no more challenge for us.
I would recommend LN2. After my vacation I will inform you of the correct price.
Edit:
In addition I hope that Xtasy can supply my container... Completely copper with a thick base.
