Over a short baseline of the last 36 hours or so, GRIM is using under 0.25 liters per hour of LN2. This is good. Eddie Bergeron has plotted the run of temperatures vs time during the cool down, and a printout of the curves is in the GRIM II logbook (kept by Jon Brinkmann). Eddie is planning to plot also the initial LN2 usage during the first couple of weeks to establish a baseline, and the results will also be available in the logbook and electron- ically. - Steve K.
