A novel design for a temperature-controlled ICR cell is described for use in black-body infrared radiative dissociation (BIRD) Studies of weakly bound systems like water clusters. Due to several improved design features, it provides a very uniform black-body radiation environment, and at the same time maintains efficient pumping for a low collision rate oil the order of 10(-2) s(-1). At the lowest temperatures reached, nominally 89 K cell plate temperature, water evaporation effectively ceases, while intracluster reactions in V+(H2O), with a small activation energy are still observed. BIRD rate constants for Ag+(H2O)(n), n = 4-6, are shown in the temperature range T = 160-320 K. For n = 6, a linear Arrhenius plot with R-2 = 0.9943 is obtained without any calibration, confirming the suitability of the cell for quantitative BIRD studies. (C) 2008 Elsevier B.V.
