The mesytec MPR-Series provides a set of state of the art multichannel preamplifier modules specially designed for single or double sided multistrip silicon detectors. The MPR series can be used as stand alone modules and can also easily be combined with the mesytec STM-16 shaping-/timing filter/ discriminator module.
Features
• 16 / 32 / 64 channel compact module.
• Sensitivity switch, factor 5.
• ESD input protection.
• Differential output 100 Ω or.
• MPR16L with Lemo output connectors.
• Pulser input.
• Bias voltage up to ± 400V.
• PCB module available for vacuum use.
Technical Data
Energy ranges The MPR series provides a switch to amplify the output signal by a factor of 5. This helps to provide large output signals even at low charge depositions and thus provides good noise immunity. With STM16+ the energy range (for gainjumper G2) is 2x specified energy range for lowest gain and specified energy range / 10 for highest gain. Another amplification factor of 5 can be added by preamp gain switch. For the 25MeV type this means: maximum 50MeV full range to 500keV full range. Pulser input The pulser is internally distributed to individual charge termination capacities. Tolerances +-10%. | Detector bias input • Lemo connector. • Maximum voltage ±400 V. • When connected detector side must be on ground level: terminate bias input wit-h 50Ω Lemo terminator. Ground connections • Ground screws on front and rear side. • There are two different ground connections:input and output ground. • Input ground is connected to the vacuum vessel if the setup is not isolated (ie. Isolated flange). • In critical environment the output ground can be connected to the NIM electronics. |
