8. Budget Model How are we going to pay for this project?
When do you expect to have a response from the financial body?
How are we to share the costs?
Please prepare a slide for discussion on Wednesday morning.

10. Other Instrumentation
Bardelli
ACTAR Workshop
Ljubljana 2008
To what can we apply the GET electronics apart from TPC oriented instrumentation?
Complete or Partial applications?
Ge (higher resolution-HiSPEC/FAIR)
Si for particle ID (high sampling-GASPARD, HYDE, EXL)
Bragg detectors (VAMOS/GANIL)
RDT (MUSETT-VAMOS/GANIL) …
Is GET DAQ a possible “standard” for high data through-put for GANIL? What must we do to make it so?

Need to have slide:
Need To Make Estimates of the Engineering Times involved.
Need to Make Estimates of the fixed costs involved.
From 1 & 2 we can obtain Price/Channel. Provide a bases for the individual demands to the different authorities.
The Contribution in engineering time will be reduced from the final bill.
Travel costs etc – to be paid by each laboratory.
The final bill – how do we pay for it?
Proportional to the number of channels?
A fixed cost part + the number of channels?
We pool all the money together … ?
Common funding from say ANR?
Need to have a kitty or money pool to perform the developments.
