Robustly non-hyperbolic transitive symplectic dynamics
We construct symplectomorphisms in dimension having a semi-local
robustly transitive partially hyperbolic set containing -robust homoclinic
tangencies of any codimension with .Comment: This article is the second part of arXiv:1509.0532
A 1 GHz RF Trigger Unit implemented in FPGA logic
Applications of Trigger Units (TU) can be found in almost all accelerators at
CERN. The requirements in terms of operating frequencies, configuration or
modes of operation change from one application to another, how-ever, in terms
of design requirements for the Trigger Unit, the operating frequency is
probably the most demanding one. In this work, we present an implementation of
a Trigger Unit almost fully embedded in the FPGA logic operating at a maximum
frequency of 1 GHz using the internal serializer/deserializer circuitry to
simplify the timing constraints of the design. This implementation allows easy
reconfiguration of the module and the development of new modes of operation,
which are described in this paper.Comment: Poster presented at LLRF Workshop 2017 (LLRF2017, arXiv:1803.07677
