- Real-Time Protection System that will prevent the MAST-U machine’s magnetic coils from damage. The White Rabbit collects the signals read from the coils and measure the level of electrical current passing through them during a plasma pulse. If the current gets too high, the Real-Time Protection System automatically kicks in – gradually winding down the power supplies so the pulse can be stopped without harming the machine.

- Real-Time Protection System that will prevent the MAST-U
|
|
|
|
|
machine’s magnetic coils from damage. The White Rabbit
|
|
|
|
|
collects the signals read from the coils and measure the level
|
|
|
|
|
of electrical current passing through them during a plasma
|
|
|
|
|
pulse. If the current gets too high, the Real-Time Protection
|
|
|
|
|
System automatically kicks in – gradually winding down the power
|
|
|
|
|
supplies so the pulse can be stopped without harming the
|
|
|
|
|
machine.
|
|
|
|
|
- This particular version of the switch has been adapted from one
|
|
|
|
|
used for data synchronization at CERN, so MAST-U is getting a
|
|
|
|
|
device with tried-and-tested performance in a ‘big science’
|
|
|
|
|
setting. Uses Xilinx Aurora streaming (no packets) at 1.25Gbps,
|
|
|
|
|
latency 0.5us.

- After an extensive study, White Rabbit has been chosen as the most promising option for the synchronization network at ESS Bilbao, a light ion linear accelerator. Therefore, first [SPEC](https://www.ohwr.org/project/spec/wiki) to SPEC tests have been performed. Now, with a [White Rabbit switch](/Switch) a new set up will be tested to provide synchronization signals for ESS Bilbao's hydrogen positive ion source (ISHP) in the near future. For 2013 ESS Bilbao is planning to test PXI SPECs ([SPEXI](https://www.ohwr.org/project/spexi/wiki)) which is the most suitable platform for the integration of White Rabbit into ESS Bilbao's general control system.

a new set up will be tested to provide synchronization signals

for ESS Bilbao's hydrogen positive ion source (ISHP) in the near

future. For 2013 ESS Bilbao is planning to test PXI SPECs
|
|
|
|
|
([SPEXI](https://www.ohwr.org/project/spexi/wiki)) which is the
|
|
|
|
|
most suitable platform for the integration of White Rabbit into
|
|
|
|

order to provide better timing signals than currently

100 km the JRP aims to improve the accuracy down to about

100 ps. Furthermore, the feasibility of a European fibre

*Following a recommendation of the international advisory

|
|
|
|
board to investigate the possibility of a time link between
|
|
|
|
|
radio-observatories at Metsähovi (Finland) and Onsala
|
|
|
|
|
(Sweden) a study on feasibility of a standard
|
|
|
|
|
uni-directional network for long-haul timing dissemination
|
|
|
|
|
using PTP-WR (Precision time Protocol- White Rabbit) was
|
|
|
|
|
initiated. We have focused on **long distance testing of
|
|
|
|
|
White Rabbit equipment**. A test link of about 1000 km
|
|
|
|
|
distance between MIKES sites at Espoo and Kajaani has been
|
|
|
|
|
set-up. This was achieved in close collaboration with the
|
|
|
|
|
Centre for Scientific Computing Ltd. (CSC), the Finnish
|
|
|
|
|
University Network and CERN, with support by VSL and SP. In
|
|
|
|
|
a 120 day comparison between GPS-PPP time transfer and the
|
|
|
|
|
1000-km long link White Rabbit time link in a live DWDM
|
|
|
|
|
network, the performance and reliability of the fibre link

were found to be excellent where the results were limited by

_Following a recommendation of the international advisory board to investigate the possibility of a time link between radio-observatories at Metsähovi (Finland) and Onsala (Sweden) a study on feasibility of a standard uni-directional network for long-haul timing dissemination using PTP-WR (Precision time Protocol- White Rabbit) was initiated. We have focused on **long distance testing of White Rabbit equipment**. A test link of about 1000 km distance between MIKES sites at Espoo and Kajaani has been set-up. This was achieved in close collaboration with the Centre for Scientific Computing Ltd. (CSC), the Finnish University Network and CERN, with support by VSL and SP. In a 120 day comparison between GPS-PPP time transfer and the 1000-km long link White Rabbit time link in a live DWDM network, the performance and reliability of the fibre link were found to be excellent where the results were limited by the statistics of the GPS–PPP link._
