Msham - A Multi-Hit Sample and Hold Multiplexer

The MSHAM is a single-width CAMAC module intended to be used for dE/dx or Z-position measurements, with a density of 16 analog channels. It is designed to record up to four hits/event per channel but the design can be easily adapted to eight hits. The charge collection time interval allowed per hit is externally controlled in the range of 50-500 ns, according to the requirements of the experiment. Besides the electrical performance of the MSHAM, i.e., linearity, noise, crosstalk, etc., the goal was to design multi-function circuits and high density packaging in order to achieve low cost per channel.
