The design of a single particle counter for therapeutical proton beams based on Low Gain
Avalanche Diodes and optimized for very fast signals is carried on in the framework of the INFN
MoVe-IT research project. Fast signal shaping front-end electronics is mandatory in this application in order to deal with particle rates of the order of hundreds of MHz per channel. Two preamplifier architectures, one based on a fast Charge Sensitive Amplifier with self-reset capabilities
and a second one based on a Trans-Impedance Amplifier have been developed in a commercial
CMOS 0.11 µm technology and submitted to the foundry.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
