Digital Feedback System : The Studies
A journal about the design of digital feedback technologies that promotes new forms of citizen engagement in the production of public services has been carried out. The study used public policy documents, health and social care literature and case studies to come up with its findings. The study found that its designed to increase the level of innovation and creativity within the public service sector. Additionally, the study found that it can help improve communication between public servants and citizens.
A research about a digital feedback system for the proton linac of J-PARC found that a stability of ±1% in amplitude and ±1° in phase is necessary to produce RF radiation compatible with the proton accelerator's electric field. One way to achieve this stability is by using a digital feedback system that registers and Stores energy in a Digital electronic bitstream.
A paper about a digital feedback system to control self-bunching of electron-cooled coasting ion beam in ion-storage rings has been made. Such a system would be used to cure self-bunching of the beam.
A study about the Beam Feedback system has been done on the International Linear Collider (ILC) which is an experimental particle collider in Europe. The study is looking at how the digital beam feedback system can improve the overall operations of the ILC. The ILC is a giant international linear Collider that has the ability to collide particles at many different energy levels. This will provide scientists with a unique opportunity to study a wide range of particles and experiments that they may not be able to do with traditional particle colliders. Thebeam feedback system is an important part of this research and it should be improved so that it can better help researchers achieve their goals. The beam feedback system is composed of a personalisation processor, FPGA-based digital signal processing board, and additional back-end components including an ADC/GPRS module and acoustic transducers. When using the beam feedback system, researchers can adjust all aspects of their experiment (speed, Energy, Position). This allows researchers to track their particles in real-time and allow for more accurate simulations of how particles are interacting with each other. Overall, the beam feedback system should help researchers achieve better accuracy in their experiments and improve overall operation of the ILC.
A review about the RF system needed for the JaERI and KEK Joint Project found that an electric field stability of +-1 % in amplitude and +-1 degree in phase is required. In order to accomplish these requirements, a digital feedback system is needed.
An evaluation about the improvement of the electron beam closed orbit at the Elettra storage ring has recently been conducted. The study found that an improved feedback system is necessary to stabilize the system and ensure a reliable feedback. Review of the current orbit measurement system is ongoing in order to make this requested improvement.
A study about the Burris gravitymeter has shown that it can produce accurate measurements of gravity and displacement. The zero-length spring principle is used in theBurris Gravity Meter, which produces results that are True to Weight, allowing you to accurately record data.
A study about the role of feedback technologies in care organisations has been conducted. Feedback technologies are used in many different ways in care organisations, but the main purpose of these technologies is to allow people to give positive or negative feedback to one another. This way, care organisations can learn from their users and make changes that will improve their services.
An inquiry about the increase in feedback system response time in a high energy electron beam application was conducted. A digital feedback system was used to monitor and control the orbit and stability of a high energy electron beam. Results showed that increased feedback system response time can lead to decreasediband formation, errors in data acquisition, and shorten the overall beam life.
A study about a digital orbit feedback control for spear was done. The system was found to be useful when working with smaller step changes with and without feedback. It also worked well during experiment cycles where large changes occurred quickly.
An analysis about the digital global feedback system (DGFB) was conducted to suppress orbit drift, low frequency beam motion, and orbit perturbed by insertion devices. Measured response matrix and singular value decomposition (SVD) [1, 2, 3] techniques were used to analyze the results. The results showed that theDFFB was effective in suppressing orbit drift, low frequency beam motion, and orbit perturbed by insertion devices.
A study about a digital feedback system for transverse orbit stabilization in the NSLS rings has been conducted. The system will use a nolinear eigenvector decomposition algorithm. It will have a wide dynamic range, and will be able to stabilize transverse orbits in the Rings very accurately. This innovation is very important for the NSLS, as it will give scientists more accurate information about their spacecraft orbits.
An article about a potential upgrade to the transverse feedback electronics in the PEP-II B factory at the Stanford Linear Accelerator Center (SLAC) requires 12-bit resolution and a minimum sampling rate of 238 Msps. The new electronics require a response time of only 2 ns, making it possible to accelerate beams using 12-bits of resolution. This would allow scientists to measure subatomic particles with unprecedented accuracy.
An inquiry about a digital feedback system for orbit stabilization has been completed and preliminary results show that it is a promising technology for construction of the NSLS. The algorithm uses a nonlinear eigenvector decomposition to stabilize the rings within their orbits. This technology should have great potential for solving many issues associated with space transportation.
A study about a digital feedback system used in homes right now is quite Limited. In order to increase the knowledge about this technology, we have created an overall control and analysis system that is based on the Texas Instruments TED FPGA The system can be broken down into four main parts: a processor, general purpose input/output controller, sample coordinator and Banditulator. The processor can run two types of software applications: real time and delaymented programming. The real time application is used to read data from a DVR or any other digital device; the delaymented programming application handles all the post processing for TV signal planning and then sends these signals to the Banditulator at precise timing intervals.
