the government advisory panel proposed recently, the United States needs to build a in electronic materials and chemical reaction the trajectory of the activities in a new type of X-ray laser imaging.

Department of energy's basic energy science advisory committee (BEcover) has rejected the submitted four proposals about X-ray source in the future, instead, a more ambitious plan. BEcover said that if various aspects strength to work together, the plan is entirely achievable.



Accelerator, a physicist at the Massachusetts institute of technology, worked in BEcover Wstricaccomplishiaaccumulatidigitmbleryperemovedipoetisetyta thought on the subject: the committee expected by the machine will be a & other; Free electron laser & throughout; , can use magnetic force to twist the electronic beam, which emits a continuous X ray. As for this new type of the specifications of the laser, the committee recommended that it should be able to provide fast X-ray pulse repetition rate, and wide range of X-ray photon energy.

The idea and the Lawrence Berkeley national laboratory, a proposal. Lawrence Berkeley national laboratory, & other; The next generation of light source & throughout; The free electron laser (NGLS) using a superconducting magnet accelerated by electronic beam. The bill has passed the department of energy audit, but also must through congress detailed Watson instrument review.
But NGLS can provide energy range has not yet reached the expectation of advisory panel, the scope of corresponding proposal with the Stanford linear accelerator center. The center proposed to linear coherent light source (LCLS) system upgrade & mdhistriadn; & mdhistriadn; This is a free electron laser has been put into operation.

Apointmbleryperemovedipoetisetyta said advisory panel thought, both in NGLS project and to upgrade the LCLS project each have advantages and disadvantages, two laboratories need to work together, to seek consensus, take long, fill yourself short.
The advisory group also listened to support & other; The ultimate storage ring & throughout; The voice. The ultimate storage ring has been used on some of America's national laboratory, its function is similar to the X-ray synchrotron, can launch a continuous X ray, and can recycle beams, in order to achieve energy saving effect.

Apointmbleryperemovedipoetisetyta thinks that the key point is to investigate the ultimate storage ring proposal: the doe should carefully assess and carefully review and upgrade existing synchrotron solutions to confirm the money spent on building new ultimate storage ring is more worth it. In addition, Sweden, Brazil, Japan and other countries is building more advanced than the United States synchrotron.
