The big, active and very communicative WRcommunity has made the White
|
|
|
|
Rabbit system a well debugged and calibrated system. In particular, for
|
|
|
|
high demands on longterm precision and stability, the extensive usage
|
|
|
|
and debugging of the WR-key components make it very reliable. ([ICRC2013

We acknowledge very helpful discussions, technical advices and support
|
|
|
|
from the White Rabbit community (in particular the CERN based team and
|
|
|
|
A. Rubini) during all phases of this project. The technical support from
|
|
|
|
both SevenSolutions and Creotech \[companies- ED\] was very helpful.
