MPPC test set-up

MPPC test set-up

Some progress for our Direct Ion Detection project: the image above shows the beginnings of a test set-up based around a Hamamatsu MPPC chip, which will be coupled to a scintillator coating to form a complete “direct” ion detection system.  This will then be combined with our VIRP chamber (for rapid vacuum instrument prototyping), allowing us to perform experiments with direct ion detection, and optimise the methodologies and technologies. This is a more refined version of the crude test set-up from a couple of weeks ago!
