  This article introduces a design of a Low Noise Amplifier (LNA), for the
field of diamond particle detectors. This amplifier is described from
simulation to measurements, which include pulses from {\alpha} particles
detection. In hadron therapy, with high-frequency pulsed particle beams, the
diamond detector is a promising candidate for beam monitoring and
time-stamping, with prerequisite of fast electronics. The LNA is designed with
surface mounted components and RF layout techniques to control costs and to
allow timing performance suitable for sub-nanosecond edges of pulses. Also this
amplifier offers the possibility of high voltage biasing, a characteristic
essential for driving diamond detectors. Finally the greatest asset of this
study is certainly the minimization of the power consumption, which allows us
to consider designs with multiple amplifiers, in limited space, for striped
diamond detectors.
