- **White Rabbit Network at GSI - stretching WR switches**: A number of White Rabbit timing system instances are currently employed for acceleration control by GSI. Each instance is application-specific, but they all are maintained uniformly. In addition, common systems for WR network management, monitoring and diagnostic are co-supervised by the control system administration with less effort. These are mostly brought by intensive utilization of networking functionalities embedded in the WR switch. Here, an improved WR network infrastructure, which was re-built last year, is presented.

- **WR deployment at LHAASO and other works**: The LHAASO experiment has been fully operational since last June and discovered PeVatrons from our Galaxy. The more than six thousand detector units are synchronized to sub-ns level with the help of WR technology. The deployment of the WR network and some running status will be given in this report.

-**Porting SPEC drivers to current Linux kernels and embedded ARM boards for WRTD applications**: In the context of distributed multistatic RADAR systems, we are considering using White Rabbit for synchronizing radiofrequency receivers. Starting with an initial demonstration receiving the continuous wave emitted by GRAVES from Eastern France at 143.05 MHz, multiple Ettus Research X310 are synchronized for complementing Doppler target velocity measurement with direction of arrival and hence location of the target. Sub-degree phase resolution along the distributed receiver array requires sub-20 ps phase alignment of the clocks driving the receivers as provided by a White Rabbit Switch associated with each X310. In order to increase the number of receiving sites by decreasing cost, size and consumption, running SPEC boards fitted with analog to digital converters on embedded boards is considered. With the wide availability of the Compute Module 4 OEM version of the Raspberry Pi 4 and its PCIe slot, the White Rabbit Trigger Distribution (WRTD) framework was ported to Buildroot used to cross-compile the embedded image. Doing so required tuning some of the driver functionality to match ARM-architecture requirements in addition to adapting to current Linux kernel API. Thanks to these efforts, runnig WRTD on embedded ARM-based boards is now functional. Perspectives include disciplining the ADC clock on White Rabbit to synchronize data sampling.

- **The future of White Rabbit**: An open discussion session with the aim of identifying past and current successes and issues and finding the best path forward for the WR community. In particular, we will discuss the latest draft of the [WR Collaboration proposal](https://cernbox.cern.ch/index.php/s/PPUdASzjKyDBVXU) and try to decide if there is enough support to launch the effort in 2022.

- **White-Rabbit-powered applications that will transform telecommunication networks (as well as White Rabbit itself)**: In this talk I will consider several emerging applications of White Rabbit, such as quantum communication and terrestrial networked positioning systems, which have the potential to transform the very nature of existing telecommunication networks. To make this real, however, continued research and development of White Rabbit is going to be crucial, and I will discuss a number of possible White Rabbit upgrades that will be essential for future high-impact applications.

- **White Rabbit applications at CERN**: A summary of some of the most important WR applications at CERN, including White Rabbit Trigger Distribution (WRTD), the BTrain system for real-time fixed-latency distribution of magnetic field values and the use of WR to distribute RF signals. All these applications benefit from the combination of excellent synchronisation and upper-bound in message latency provided by WR.

- **New White Rabbit developments for Low Level RF systems**: In 2021, a new Low Level Radio Frequency system has been commissioned for the Super Proton Synchrotron at CERN, relying entirely on WR for ultra-low-jitter RF distribution. The presentation describes the WR components developed within the scope of the LLRF project (eRTM14/15, WR2RF-VME, WR Switch Low Jitter), thanks to which WR can achieve performance (phase stability and phase noise) previously reserved for analog RF distribution systems. A brief description of the hardware, firmware and software as well as the techniques used to improve the WR performance will be also provided. |
