11. Physics cases for (active) gaseous detectors
D. Suzuki, O. Poleshchuk, B. Fernandez-Dominguez, A. Corsi, M. Caamaño, M. Cwiok…
Direct reactions, resonant reactions, inelastic to GRs, knock-out reactions, induced fission, photodissociation…
One setup “to rule them all”? Impossible… - Beam detection or not - Charged particles: huge energy range, all angles, PID - 𝛾-ray detection? - Costs!
Specialised designs
Share where possible: Pad-plane detector? Charged-particle array? Electronics?

13. Versatility and specialisation
Pad-plane detector
Depends upon event rate, detection gas → gain, dynamic range…
Amplifiers: Micromegas, GEM, THGEM, combinations… Plane: pads, strips, dots…
Knowledge base: high-energy physics → a lot of work to do for nuclear structure
Charged-particle array
One-stage array ok for some cases: (d,p), resonant reactions, inelastic to GRs
Telescope for light particles at forward angles: FAZIA/FARCOS – start collaboration!
Integration with 𝛾-ray detection: Significant compromises threshold/efficiency Dedicated studies, €€€!

14. Integration: electronics
P. Russotto, G. Jaworski, (M. Caamaño), M. Cwiok, A. Corsi, F. Cappuzzello, S. Capra, P. Ottanelli, S. Valdré, G. Wittwer, A. Laffoley…
GET electronics
Very successful for TPCs!
Integration with GTS with BEAST
Attempts to use it with scintillators and silicon detectors: - in progress (GANIL, KU Leuven) - dedicated preamps: →FARCOS, →TRACE, …?
Other dedicated (front-end) electronics
NEDA, MAGNEX, EXOTIC, GARFIELD, FAZIA… Different philosophies (store samples or final number)
Are we duplicating work? Several person × year engineering efforts!

15. Conclusions Do we need/want a universal detector?
In most cases we do not. [Diversity is a resource] We (GDS) want re-configurable detectors made of standard, well-tested elements But some aspects need to be coordinated
Are we ready for a coordinated approach to electronics for nuclear structure experiments?
NuSpIn NA in ENSAR2?
Dedicated preamplifiers + GET?
Dedicated preamplifiers + Commercial digitisers?
Common ASIC and ADCs, custom preamp and FPGA?
Where does the progress come from, then?
Mostly from other fields (high-energy, medical, home security, aero/astronautics, telecommunications) We have to be alert, exploit and adapt
