From DESY: Record wavelength at FLASH – First lasing below 4.5 nanometres at DESY's free-electron laser
A recent record at DESY's FLASH accelerator is a direct result of the TESLA Technology Collaboration a new cryomodule built at Fermilab brings the energy of the electron beam right up and the size of the laser beam right down.

The spectrum of the record laser pulse peaks at a wavelength of 4.45 nanometres.
For the first time, FLASH produced laser light with a wavelength of 4.45 nanometres; thus, DESY's free-electron laser for soft X-ray light considerably beat its previous record of 6.5 nanometres. At the same time, the peak intensity of single light pulses nearly doubled, with 0.3 millijoule. Prior to this, there was a five-month machine upgrade, above all with a significant improvement of the superconducting linear accelerator and the installation of a seeding experiment together with the University of Hamburg.

Jie Gao, professor at the Institute of High Energy Physics (IHEP) in Beijing, China, has been appointed by the Asian Committee for Future Accelerators (ACFA) to be the new chair of the Asian Linear Collider Steering Committee (ALCSC) for a term of three years. The appointment occurred during the First International Particle Accelerator Conference, IPAC'10. “I feel that it is a great honour for me to serve as the new chairman of ALCSC, and at the same time I feel a great responsibility to fulfil this role of promoting and coordinating ILC activities in Asia with good accordance and communication with other regions,” said Gao.

Director's Corner
Flexibility in the ILC design
Today's issue features a Director's Corner by Ewan Paterson, member of the Global Design Effort Executive Committee.

Schematics of the ILC with the Reference Design Report layout on the left and one "SB2009" version, which is under study, on the right.
In a new large accelerator complex which will take years to get approved and constructed, one must maintain some degree of flexibility in its design as many things can change before a construction start. The accelerator physics and technology that constrains the performance will advance and the knowledge of the physics which determines its future physics programmes will be better known and continually evolving. At the same time a complete baseline design and associated cost estimate is needed to support the many technical and cost reviews that will be required to obtain the necessary global support and funding.
