Overview

• EEE PROJECT

24 Channels LVDS Signal Amphenol Cables
?
Personal Computer equipped with DAQ System
and Human Interface
All equipments need to be easy to operate by
teachers and students in the schools To speed up
the set up of the project in the 7 sites we plan
to use commercial devises
4
Front-End cards and cables

• EEE PROJECT

NINO ASIC (ALICE TOF)
AMPHENOL cables
5
Patch panel (To be designed)

• EEE PROJECT

The Amphenol cable coming from the FE card is a
special custom connector with 25 pin not
compatible with inputs of the commercial TDC we
plan to use. (35 pins). We are developing a
patch panel to adapt the inputs
6
VME crate

• EEE PROJECT

The best solution is to use a commercial small
crate with 7 available slots (Mini VME Crate)
7
Crate Controller

• EEE PROJECT

V1718 CAEN (USB 2.0 bridge) The choice of this
controller is mainly due to the possibility to
easy interface it with a PC (via USB
2.0)Software drivers available

Trigger system

• EEE PROJECT

Custom trigger systemwith AND/OR masked
programmable logicAND of the three FE cards
on the same sideAND of the two sides

DAQ system and GUI

• EEE PROJECT

• ALICE DATE with PAW (not very suitable for
  students)
• LabView (commercial) (license expensive but
  simple to use)
• Custom Readout and Human Interface (software
  to be developed)

12
GPS receiver

• EEE PROJECT

• CAEN add-on for A1718 based on Motorola GPS
  Chip (To be developed in collaboration with
  CAEN) - Commercial add-on a. VME based
  (IDGN) b. Trimble Resolution full-featured,
  low- cost, embedded GPS Timing Receiver
  (50 ns PPS/UTC)

13
Large scale installation

• EEE PROJECT

In order to reduce space, cost and complexity of
the set up- Integrate the whole RO and DAQ
system in a small box (DAQBox), where we could
just plug in the signal from FE cards - Use of
embedded processor like a PMC board - USB2.0 or
Ethernet interfaces (DAQbox link) - Integrate
the developed DAQ and Human interface

Successful Example for Medical Application

Conclusions

• EEE PROJECT

The implementation of the readout system for the
first 7 sites is presently ongoing. The
commercial modules are being ordered. The DAQ
software is under development.
