A freeze indicator employs, as active indicator element, dispersion of solid particles in a liquid medium which can be water or aqueous and which coagulates to provide an irreversible appearance change when subject to freezing. The liquid dispersion can be contained in an indicator volume around which extends a vapor block layer. The vapor block layer can prevent loss of liquid vapor from the dispersion and consequent drying out and dysfunctionality of the freeze indicator. For containing an aqueous medium, bilayer and trilayer laminate materials can be used which have a low water vapor transmission rate. The active indicator element can be a dilute colloidal dispersion of a metal such as gold or silver or other inorganic pigment material in water or an aqueous medium. Some embodiments avoid use of dispersants and the like and employ an active indicator element consisting of inorganic pigment particles, water and optionally an ice nucleating agent. Heavy water, or deuterated water can be components of the water, if desired.

A charged particle beam detection system (10) that includes a Faraday cup detector array (FCDA) for position-sensitive charged particle beam detection is described. The FCDA is combined with an electronic multiplexing unit (MUX) (2) that allows collecting and intgrating the charge deposited in the array, and simultaneously reading out the same. The duty cycle for collecting the ions is greater than 98%. This multiplexing (2) is achieved by collecting the charge with a large number of small and electronically decoupled Faraday cups. Because Faraday cups collect the charge independent of their charge state, each cup is both a collector and an integrator. The ability of the Faraday cup to integrate the charge, in combination with the electronic multiplexing unit (2), which reads out and empties the cups quickly compared to the charge integration time, provides the almost perfect duty cycle for this position-sensitive charged particle detector (10). The device (10) measures further absolute ion currents, has a wide dynamic range from 1.7 pA to 1.2 μA with a crosstalk of less than 750:1. The integration of the electronic multiplexing unit (2) with the FCDA further allows reducing the number of feedthroughs that are needed to operate the detector (10).
