Electronics
- Debate about the meeting planed in
- Some think that the electronics issue should
be discussed at a later stage, once all specifications are decided.
- Some defend the idea that many pertinent
tricks can be studied and learned on test-bench already now. Everybody agrees
on this.
- Conclusion – Meeting in
Technical report
· physics cases :
- The question of performing simulations
including realistic physics generators for each
- This discussion leads to the conclusion that
not mandatory at this stage. For determining the specifications of the device,
the only input quantities are a range of velocity for the g-ray emitter, a cascade of
low-energy g ‘s given
by its multiplicity and a high-energy photon characterized by its energy. The
outcome of the simulation does not depend on how these parameters have been
prepared i.e. on the entrance-channel, and basic generators are therefore
well-enough so far.
- Yet, one can think about performing realistic
simulations (also including the possible dead layers) for the couple of key
experiments to be discussed in the technical report.
· simulations :
- Arriving to a final conclusion on the most
suited design within one year is very challenging:
It is agreed that better coordination of the work distribution within
existing manpower would be sufficient.
· key
experiments :
- First experiment (Day1) most probably at S3
and with a gaseous beam?.
-The spokesperson of the experiment should
ensure with the “Simulations” WG’s that realistic
simulation is done for this experiment.
- In the perspective of the technical report
(to be written soon), it is recommended that several key experiments are
proposed to be run at the early stage of the development of
· mechanical
design :
- Some money will be available from the
SP2PP/FP7 to be spent rather soon (2010) in
- It was
agreed that it is too early to decide on how/for what this money can be used.
· detector
testing :
- IPHC Strasbourg is waiting for the detector
delivery. It was suggested that the project leader will help finding the needed
detector
- Measuring properties of the phoswich (energy and time resolution of the LaBr part of the phoswish)
remains the most burning priority.
· PROVA by M.Rousseau :
- Goal : R&D of
à Test
new and original phoswich concept
à Build a
prototype made of 3´3 detectors
- Steps of how to proceed already well-defined
- Half of the budget for equipment, electronics, …
Half
of the budget for 6 year post-doctoral positions (3´2years)
- Simulation of transport, reflection,
collection of light, …
· discussion :
- Important :
O.Stézowski and O.Dorvaux,
for the “Simulations” and “Detectors” WG, respectively, should write and send a
protocol on how to proceed.
Conclusion
- Next collaboration meeting in
