VIRP chamber spectrometer v2.0

VIRP chamber spectrometer v2.0

A little more progress for our Direct Ion Detection project: the images above and below show some developments of our VIRP chamber (for rapid vacuum instrument prototyping), showing v2.0 of the charged particle spectrometer stack (following a rebuild) with some of the in vacuo wiring attached.  Time-lapse build footage to follow!  This configuration will allow us to perform experiments with direct ion detection, and optimise the methodologies and technologies.

Update: time-lapse build footage is now online.
