Charge Decay Test in Material Analysis

Currently there are not too many reliable methods available for charge decay measurements. Mr. John Chubb wrote an interesting article about existing test methods in 2002: “There are several methods for the measurement of ‘charge decay’ described in ‘standard’ documentation and in published literature. The methods of measurement are very different and many of the methods do not provide the information likely to be expected by uninitiated/unskilled users and are susceptible to the construction of the materials tested.” [1]
