Summary
CMS is in the end of R/D and in the beginning of production
Most Front-End electronics for test beam is dedicated
Very often UUT
Electronics to “connect” to test facility needed

Conclusion 1
Keep NIM as is, but make sure that crate PS get serviced
Get rid of CAMAC
CBD weak point, getting old, fragile, less supported (soft)
Replace with equivalent VME modules in some cases
Examples: (used by CMS ECAL and others):
TDC Lecroy 2228 ( clock-trigger )
TDC Lecroy 2277 ( multi hit trigger counters )
Scalers Lecroy 2551
Pattern units
Output registers.
Sometimes ADC Lecroy 2249, ADC Lecroy lg8252

Conclusion 2
Develop VME
Buy or Develop “Stupid modules”, i.e. No Soft…
Level shifters
NIM – ECL, ECL - NIM
NIM – TTL, TTL – NIM
ECL – TTL, TTL – NIM
Be careful with short life equipment
Software obsolescence
PCI-VME interfaces, etc.
Study “new” standards
Compact PCI
3U, 6U, 9U, …
Develop serial transfers
gigabit Ethernet, USB2, FW, FW2, or similar

Conclusion 3
Provide a set of high performance laboratory instruments
Oscilloscopes, pulse generators, TDR, optical, etc.
High rental fee
Probably not possible to get to pay off for the pool, but for the organization…
Promote user friendly high performance instruments
Enable short rental periods hence sharing
Coordinate purchase of instruments
Coordinate service of instruments
