Construction, test and operation in a high intensity beam of a small system of microstrip gas chambers (1997)

Barr, A J, Bachmann, S, Boimska, B, Bouclier, Roger, Braem, André, Camps, C, ...

We describe the construction, test and installation procedures, and the experience gained with the operation of a small but complete system of high rate Micro-Strip Gas Chambers, made on thin...

Progress with diamond over-coated microstrip gas chambers (1997)
