LAB LIFE -.- EQUIPMENT

DAQ

The hardware of the DAQ, FEBEX, is manufactured at GSI (Darmstadt, Germany) laboratory. The software for managing the DAQ is also produced at GSI (Multi Branch System). FEBEX cards, with FPGA, feature full digitization of the signal coming from the amplifier, enabling Digital Pulse Shape Analysis (DPSA). DAQ able to handle 80 channels. Go4 software is used for on-line monitoring of the spectra.

Detectors

Double Side Strip Silicon Detectors (DSSSD) (Micron W1 D/S): 1x40 um, 1x17 um thick, square 50x50 mm^2 dimension PAD Silicon detectors (Micron MSX25 SS): 2x500 um thick, square 50x50 mm^2 dimension

Strip Silicon detectors (Micron QQQ2 SS): 2x40 um thick, 90 deg

PAD Silicon detectors (Micron QQQ1): 2x500 um thick, 90 deg

FFF2-500 (DSSSD) (Micron): Trapezoidal for GRIT detector

Poli-Crystal Diamond detector: 1x500 um thick 5x5 m^2

Byass supply modules, circuitery & cabling for handling pulses.

Vacuum System

Stainless steel vacuum chamber measuring 600x400x300 mm^3(length-width-height).

  • Upper opening (hatch) with hinge and anchoring system
  • 4 “half nipple” type side openings with dimensions for 6-inch ISO100 flanges.
  • Additionally, a KF40 lower opening. Protective grille.
  • Mechanical support with wheels and ground anchoring system, with a height of the mechanical support of 1 meter. Elevation system to make the camera rise ~150 millimeters.

Vacuum system able to operate down to 10^-5 mbar

Fast Electronics

NIM modules for fast (logic) signals used for building different trigger schemes for event validation are powered by two NIM crates. Trigger ratemeter.

Amplifiers & Preamps

A total of 80 channels can be handled by the combination of DAQ+preamplifiers with adjustable dynamical ranges (Manufacturer: Mesytec). In order to check the electronics chains a pulse generator is used.
